- Description: From Introduction: Thus for the black South African, the act of creative writing is inescapably a form of political action, and unless he turns his back on the reality which confronts him and retreats into a private imaginary world, it is also a form of social action, Yet Ezekiel Mphahlele has rightly cautioned that "creating an imaginary world" can never be an effective substitute for social act ion . Composing fictions about social and political problems is an indubitably oblique way of seeking a solution to them, and even the tendentious recreation of reality is only a metaphor for its actual transformation. Protest writing in South Africa is paradoxically a form of social action which is also only a parasitical imitation of social action, and therefore its avoidance . The freedom of literary creation described above is ambiguously not only a freedom to express reality, but also a freedom from the constraints of reality. And this suggests why the outlaw was such an important symbol to an earlier generation of rather more self-conscious writers.

Satan and Lucifer: a comparison of their metamorphoses from Angel to Devil in Milton's Paradise lost and Vondel's Lucifer and Adam in Ballingschap

- Description: The aim of this thesis is to compare the poetic delineation of the character of Satan in Paradise Lost with that of Lucifer in Lucifer and Adam in Ballingschap, and to consider the influence of the genre in each case , not in order to prove similarities or differences , but rather to allow the characters to illuminate each other. Both Satan and Lucifer develop progressively from angel to devil in the course of the poem or play. However, this process is more than just a physical metamorphosis, or even a moral degeneration. It is in each case a process of identity change, intensely and consciously experienced by the character. The fall is a movement from God to Self. The unfallen creature's integrity consists in his submergence in the Being and Will of God; for the fallen creature integrity means a separate, independent self-hood. In rebelling against their role and duty as Archangel, Satan and Lucifer rebel against submergence in the Being of God and thus against their very nature and the order of things. Consequently they experience personal and psychological disintegration. From this condition of imbalance and uncertainty they both develop to a new state of personal reintegration and unequivocal identity, now as Arch-fiend. In neither case is the process instant or entirely concurrent with the physical fall into Hell. Rather, it is protracted, hence the division of this thesis into sections that focus on the different stages in the development: Archangel, Arch-rebel and Arch- fiend (introduction, p. ii-iii).

- Description: The Katberg Sandstone is an arenaceous formation occuring stratigraphically three querters of the way up in the Beaufort Group in the south-eastern part of the main Karoo basin. A sedimentological study was carried out on the Katberg Sandstone and adjacent formations, in a 2 000 km² area south of Queenstown. Stratigraphic sections were measured and lithofacies based on the style of Miall (1977) were established for the Katberg Sandstone, Balfour and Burgersdorp Formations. Stratigraphic relationships show that the Burgersdorp Formation in the study area, is the lateral (distal) equivalent of the Katberg Sandstone. The changeover from sandstone to predominantly shale lithology occurs roughly east-west between Cathcart and Whittlesea. Stream hydraulic theory is discussed and the sedimentary structures of the various lithofacies are explained in terms of this theory. An analysis was done of thirty-four palaeochannels, and their various ancient flow characteristics were derived via multiple regression equations and a FORTRAN computer program. A statistical analysis of bedform structures, showed that flat-bedding of the upper flow regime is the dominant sedimentary structure of the Katberg Sandstone. Trough cross-bedding originating in aqueous dunes and planar cross-bedding of transverse bars, are fairly well represented while ripples are virtually absent. The opposite applies to the Balfour Formation where lower flow regime structures, viz., ripple cross-lamination and trough cross-bedding predominate. There is an even spread of (upper) flat-bedding, trough cross-bedding and ripple cross-lamination in the Burgersdorp Formation. Detailed measurement of typical short sequences from sections of the three formations, and transition matrix analyses, showed the facies assemblages to be of three stream types: (i) Katberg type: similar to Platte type of Miall (1977). Sediments were deposited by swiftly flowing, low sinuosity, braided, ephemeral streams with a predominantly sand bedload. Each flow started with preconsolidated silt and mud (flakes), and movement of exogenetic pebble lags. Channel avulsion and deposition of mud drapes in higher topographic levels of the stream were common phenomena. (ii) Balfour type: characterised by lateral accretion point bar type sequences of high sinuosity streams, and vertical accretion floodplain deposits. Lower flow regime dune and ripple bedform structures overlying (upper) flat-beds indicate a loss of stream power with channel migration. (iii) Burgersdorp type: similar to Katberg type for sandstone units, also crevasse-splays onto thick subaerially exposed floodplain aggradation reddish shales. Conventional microscopy and SEM studies showed tremendous diagenetic effects mostly in the form of secondary quartz growth in the sandstones of the three formations. Electron microprobe analyses were done on titanomagnetite grains from heavy mineral layers of the Katberg Sandstone, so that thermometric predictions could be made on provenance rocks. Palaeocurrents of the Katberg Sandstone are mostly Rank 4 and 5 types (Miall, 1974), i.e., they were generated within bars with not much change in stream orientation. Burgersdorp and Balfour formation palaeocurrents are Rank 1 - 3 types. In the case of the former this is owing to directional changes in channels as a result of frequent crevasse-splays, and in the case of the latter owing to differences in orientation between entire tracts of highly sinuous palaeostreams. Palaeocurrent directions in the Katberg Sandstone indicate a southeasterly provenance which accords with the findings of other Beaufort Group workers. Bed relief index calculations (Smith, 1970), made on Katberg rocks, considered together with the abundance of planar cross-bedding (of transverse bars) and apparent absence of longitudinal bars, testify to the deposition of the Katberg Sandstone in the distal parts of the braided stream environment. The Beaufort sediments of the study area have the sedimentological characteristics of a molasse sequence, but a different implied tectonogenesis. During Balfour sedimentation the equilibrium base was being raised very slowly at the source and complete fluvial sequences were deposited under a humid temperate climate, on a slowly subsiding plain. During Katberg/Burgersdorp times, source area tectonism was pronounced but interrupted and incomplete sequences were deposited under an arid climate. Provenance rocks for the formations studied included biotite mesoperthitic granite, granulite, charnockite, granite porphyry, granophyre, metaquartzite, greenschist and possibly diorite, epidosit e and alkaline volcanic rocks. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: A study of the story of Cupid and Psyche within the context of the Metamorphoses as a whole reveals a recurrent pattern of themes, motifs, and images, which indicates that the story symbolises the experiences of Lucius. The Judaeo-Christian Greek meaning of psyche, oneself, implies that Psyche is a symbol of Lucius. This is borne out by the similarity of their experiences, and by the fact that they both have the same character traits of simplicitas and curiositas. Cupid's warnings to Psyche concerning the control which Fortuna has over her life further establish the connection between Psyche and Lucius, whose life is controlled by blind Fate. Military imagery, and images of light and dark, which occur in connection with Cupid and Psyche, also describe the experiences of Lucius. Venus symbolises Isis, as is indicated by Isis' identification of herself as Venus, in addition to many other deities, at the end of the Metamorphoses. Once again imagery, this time of the sea, makes this relationship clear, while military imagery implies a parallel between the relationship of Psyche and Cupid, and that of Lucius and Fotis. Jupiter intervenes in Psyche's misfortunes, just as Isis saves Lucius from his hardships. Juno and Ceres are also identified with Isis at the end of the Metamorphoses, thus linking the story of Cupid and Psyche with the life of Lucius.

This situation prompted the present study on the elements Ni, Co, Cu, Pb , Zn , Au, Ag , Mo , Sn, W and U. The behaviour of the elements Ni, Cu, Pb , ZN, Au, Sn , W and U has been studied experimentally in some depth. Ag has been moderately studied, but there is very little information about Co and Mo. Studies on the complexes formed by the elements within the hydrothermal and aqueous environment are often inconclusive and controversial , but conclusions are drawn as to the more likely complexes formed . A genetic classification of ore deposits is used as a framework for the discussion . The source of the elements is regarded as being the mantle, and therefore discussion on other possible sources is beyond the scope of this dissertation. The crystal chemistry and geochemistry of the elements are presented and the essay concludes with a discussion on the elements within their depositional environments

- Description: The primary production of Spartina maritima, the dominant macrophyte of the intertidal salt marshes of the Swartkops estuary, was determined for inclusion into the proposed ecosystem model. Several methods for measuring net production devised for North temperate Spartina species were used, as no single method was considered reliable for the local species. In addition, a new method was devised to take into account the aseasonal growth behaviour of S. maritima . Most energy for growth appears to be directed into leaf production, rather than shoot growth. Live net production values were 523-680 g m⁻² yr ⁻¹, which are generally lower than estimates of N. American Spartina species. Total Live production of S. maritima for the whole Swartkops estuary was 495,6 x I0³kg yr ⁻¹, which is an estimation of potential food resources. Formation of S. maritima detritus by decomposition was significantly related to air and water temperatures. Thus detritus production showed a wide seasonal variation about a mean of 374 g m⁻² yr⁻¹. The total S. maritima detritus production of 307,5 x I0³kg for the whole Swartkops estuary was determined as an estimate of available food resources. Export of detrital material from Spartina marshes to estuarine waters was negligible. Even during a maximal Equinoctial tide, only 6,26 dry g m⁻² detritus was exported from the creek catchment area of Spartina stands. This study has shown that concepts evolved for North temperate estuaries should be carefully considered before being applied to local situations, particularly in view of the relatively low, aseasonal production of S. maritima and the negligible contribution of its detritus to estuarine waters. Furthermore, it is essential that utilisation of primary production by secondary producers be determined before the function of the estuarine ecosystem may be understood

- Description: This study embraces two aspects of closed system culture: (a) a comparative study of four different biological filtration treatments, and (b) a quantitative determination of the nitrogen flow in a particular biological filtration system. Twenty 0,5 g juvenile Penaeus indicus Milne Edwards were cultured for approximately two months in four different kinds of sea water recirculatory systems with bacterial filtration, algal filtration, algar plus bacterial filtration and water exchange (25% every 3 days). Growth was comparable to that found in the literature for P. indicus. Nitrification occurred in all systems irrespective of the type of biological filtration employed. Ammonia, nitrite and nitrate levels were reduced by the algae, but nitrate accumulated to approximately 30 mg NO¯³ -Nℓ¯¹ in those systems without algae. Depletion of trace elements (Cu, Fe, Zn, Hn and Co) by the algae did not occur due to trace metal replenishment from the addition of food. No marked changes occurred in the concentrations of the major cations (Ca⁺⁺, Mg⁺⁺, Na⁺ and K⁺), but a small increase in Ca⁺⁺ levels was detectable in those systems with oyster shell chips in the filtration medium. Only minor changes occurred in oxygen or pH values in the various systems tested. Inorganic carbon levels showed major increases in the algal filtration systems, while a slight drop occurred in the bacterial filtration systems. The increase in the algal filtration systems was thought to be due to the formation of carbonates and bicarbonates by the reaction of respiratory CO₂ with unionized ammonia and water. Suggestions are made as to how closed systems can be improved upon. By determining the rate of excretion of P.indicus as related to size and temperature, its faecal production, and the nitrogen content of P.indicus, its food and faeces, the nitrogen flow within a system could be calculated. P.indicus was found to have an assimilation efficiency of 88,93% and a food conversion ratio of 3,49:1. Of the total dietary nitrogen input into the system, P.indicus ingested 69,02% - 19,80% of which was used for growth, 41,58% excreted and 7,64% lost as faeces. The remaining 30,98% of the total nitrogen input can be regarded as excess food nitrogen. The total nitrogen loading on the biological filtration system was found to be 80,20% of the total input of dietary nitrogen. The ability of various types of filamentous algae to remove these nitrogen compounds was determined. Suggestions are made as to the application of this information on nitrogen flow to the culture of P.indicus

Of the total dietary nitrogen input into the system, P.indicus ingested 69,02% - 19,80% of which was used for growth, 41,58% excreted and 7,64% lost as faeces. The remaining 30,98% of the total nitrogen input can be regarded as excess food nitrogen. The total nitrogen loading on the biological filtration system was found to be 80,20% of the total input of dietary nitrogen. The ability of various types of filamentous algae to remove these nitrogen compounds was determined. Suggestions are made as to the application of this information on nitrogen flow to the culture of P.indicus

The different types of ionosonde, their prime objectives, and their relative merits and demerits are discussed. The various types of code and their correlation functions are described. The essential requirements of the new system are listed, and suitable codes are found for it. Computer calculations and mathematical derivations demonstrate the (theoretical) suitability of these codes under all conditions. Essentials of the mode of operation of the system and details of its design are specified, and computer simulations are used to examine relevant aspects of its operation. Finally, since the construction of the system is not complete and results cannot therefore be presented, the present state of construction of the system is described

- Description: New geochemical data consisting of major and 15 trace element analyses are presented for 41 rocks from three andesitic and associated basaltic rock occurrences in the North Eastern Cape Province. These include the Pronksberg, Belmore and Roodehoek localities. Field evidence suggests that the three andesites were emplaced during the early stages of Karoo volcanicity. Geochemical variations within the Pronksberg and Roodehoek andesite are small, manifesting the undifferentiated nature of the magmas. Variations within the Belmore andesite are interpreted as representing fractionation of orthopyroxene, accompanied by only minor plagioclase fractionation. Differences in trace element concentrations and inter-element ratios between the andesites and associated basalts of the Pronksberg and Belmore volcanic suites precludes the possibility of the two rock types being genetically related. Geochemical differences constrain the possibility of the three andesites being cogenetic. Magmatic processes resulting in their formation are, however, thought to be similar. The differences in chemistry between the Pronksberg Basalt (High K Type) and Pronksberg Basalt (Drumbo Type) are interpreted as representing the combined influence of weathering, the presence of amygdales and the within-flow variations of alkali elements on the Pronksberg Basalt (High K Type). Similarities in petrography and chemistry justifies a correlation of the Pronksberg Basalt (Drumbo Type) with the Drumbo Basalt Member in the Barkly East area. Data for the Drumbo Basalt (This study) in the Barkly East area confirms and complements previously presented data. Normative chemistry and strontium isotope data indicate a process involving crustal assimilation or melting of crustal rocks as being the most likely explanation for the genesis of the Karoo andesites , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: In this dissertation the use of general systems theory as an aid to knowledge building, and the refinement of intervention in social work, is investigated. It is held that the social work view of man, and the profession's declared objectives, determine a structure and function for the client.which cause the social worker to resort to psychological and sociological perspectives in his intervention programme. However, the two disciplines concerned formulate their respective perspectives without regard to each other. The disparity between these perspectives present problems when they are incorporated into social work knowledge. The latter, as it is, is characterized by an unco-ordinated body of suppositions, facts, thoughts and theories. The social work literature on the use of the systems approach displays a lack of detailed description of general systems theory and the open living system. Because of this shortcoming it was decided to pay particular attention to general systems theory and the concept of the open living system. Since a system's view of man forms a firm basis for the appreciation of systems theory in psychology and sociology it was decided to include such a consideration. Following on this is an analysis of two perspectives held to be particularly relevant to social work, viz. the personality system and the social system. This leads finally to a description of the social work client as a system, as a sub-system and as a supra-system. Provision is made for the incorporation of psychological and sociological perspectives in social work intervention. It is subsequently concluded that the application of general systems theory has advantages for social work. It facilitates the incorporation of perspectives for psychology and sociology without distortion, promotes the integration and consolidation of social work knowledge, and brings the discipline into relation with the disciplines of psychology and sociology

- Description: This study examines the settings in Jane Austen's six novels. Chapter I introduces the topic generally, and refers briefly to Jane Austen's aims and methods of creating her settings. Short accounts are given of the emphasis put on setting in the criticism of Jane Austen's work; of the chronology of the novels; and of the use made of this aspect of the novel in eighteenth-century predecessors. Chapter II deals with the treatment of place in Northanger Abbey, Sense and Sensibility, Pride and Prejudice, Mansfield Park and Emma. The consideration of five novels together makes it possible to generalize about aspects of place common to all , and to discuss particulars peculiar to individual novels without, I hope, excessive repetition. The chapter may be thought disproportionately long, but this aspect of setting is most prominent and important in the delineation of character. Chapter III discusses the handling of spatial detail and time in these five novels. Chapter IV offers a fuller analysis of what is the chief concern of this thesis, the nature and function of setting, in respect of the single novel Persuasion, and attempts to draw together into a coherent whole some of the points made in Chapters II and III. Persuasion separates conveniently from the other works, not only because it was written after them, but more importantly because in it there is a new development in Jane Austen's use of setting. Some critics, notably E.M. Forster and B.C. Southam, have found startlingly new qualities in the setting of Sanditon, and, certainly, the most striking feature of the fragment is the treatment of place. But Jane Austen left off writing Sanditon in March 1817 because of illness, and the twelve chapters make up too small and unfinished a piece to be considered in the same way as the other novels. The Watsons, too, except for some references to it in Chapter I, does not come within the scope of this dissertation. Another introductory point needs to be made briefly. Where it is necessary, the distinction between Jane Austen and the omniscient narrator is observed, but generally, partly because it is clear that Jane Austen's values are close to those of the narrator, and partly because it is convenient, traditional and sensible to do so, the name "Jane Austen" is used to refer both to the actual person and to the narrator of the novels.

But, as Roland Barthes has pointed out: "How can we tell the novel from the short story, the tale from the myth, suspense drama from tragedy ... without reference to a common model? Any critical attempt to describe even the most specific, the most historically orientated narrative form implies such a model. "I Hence, because phenomenology is somewhat alien to the Anglo-American critical sensibility, I must temporarily reverse this emphasis and discuss the phenomenological "model" that underlies my investigation of James and the nouvelle form. Elsewhere phenomenological theory will take precedence only when it throws light on what is a highly elusive genre.

War is one of the most violent of man's past-times, yet many of the atrocities committed are termed heroic deeds.

Scientlsts and philosophers have puzzled these paradoxes for centuries, and this effort to unravel the mystery of violence and aggression bears a fateful significant.

In London, violent crimes increased by 39 per cent in three years. Even sports events (the soccer fans stage gang wars at most soccer matches nowadays, especially in England,) and entertainment ---books, movies, television--- have become permeated with violence.

- Description: The Xhosa people of the south-eastern part of South Africa have been involved in migratory labour for three generations and more. This study is concerned with the experience of migrant labour among the Gcaleka, who form part of the Xhosa cluster, and who reside in the Willowvale district of the Transkei. It is primarily an attempt to examine and understand the ways in which conservative ("red") Gcaleka society has adapted to the institution of large scale, oscillating labour migration, by looking at the "meaning" of migrant labour to the people involved, and in terms of the relationship between rural social structure and going out to work in town or mine. Much of this meaning and of the relationship between structure and migration is evident in certain ritual and symbolic actions which are associated with a labour migrant's departure from and return to the community. The bulk of the study, therefore, is taken up with a description and analysis of these "rituals of labour migration". An attempt has been made also to relate the rituals of labour migration to the structural principles of society and to underlying moral and religious beliefs and values, and also to the wider Southern African socio-political framework of which the Gcaleka are part. During fieldwork constant reference was made by informants to (ukwakh' umzi) the importance of "building the homestead" and the role of migrant labour in this. The procedure followed here, therefore, after having dealt with basic "background" material and having given an indication of the economic dependence of Gcaleka on migrant labour, is to take the individual homestead as a central reference point. Certain important aspects of social and religious life (kinship, ward section organization, economic relationships and the ancestor cult) are discussed from the point of view of the homestead and the relationships between homesteads in order to outline basic social organizational principles and to identify the socio-economic importance and cultural meaning of migratory labour to conservative Gcaleka. This leads into a discussion of Gcaleka morality in an attempt to demonstrate that the two basic organizational pr inc iples, patrilineali ty and neighbourhood, and their interrelationship, have a counterpart in moral thought. This discussion involves also some tentative ideas regarding the nature of the relationship between morality and religion in this society. All this, it is hoped, provides a basis for the description and analysis of the rituals of labour migration, which follow and which express, inter alia, the importance of the homestead, the organizational importance of kinship and neighbourhood, and certain basic moral precepts. Particular attention is paid to the most elaborate and spectacular of these rituals, the umsindleko beer drink. A separate section is devoted to an attempted analysis of the rituals in terms of Van Gennep's well known schema of rites de passage. Here the absent migrant is viewed as being one who has been separated from society and who has entered a liminal state, to be incorporated back into society once he returns from work. The extent to which liminality is accompanied by the experience of what Victor Turner calls "communitas" is also considered. The general conclusion is that the rituals of labour migration serve as a cultural device to rigidly separate the world of work from the morally superior home reality, to reinforce acceptance of the culturally determined role of migratory labour and migrant labourers and to relate the migratory experience to rural social structure in such a way that the threat of migrant labour is overcome and the rural structure strengthened. To answer the question of why this standpoint towards labour migration has been adopted, it is necessary to outline the position of the Gcaleka within the political economy of Southern Africa, and it is argued that the maintenance of conservatism and the interpretation of migrant labour in terms of the rural structure is largely a response to this position

- Description: Introduction: The macroporous Amberlite XAD resins were coated with LIX-64N and examined for the rate of uptake of copper . XAD-7 was by far the best support and gave a satisfactory rate of uptake up to loadings of 60% (w/w). The specific surface area of XAD-7 was measured by the adsorption of methylene blue from aqueous solution. The area of the wetted resin was five times less than that of the dry resin. LIX-65N was purified and the anti isomer characterised using spectroscopic techniques . The rate of uptake of copper was not improved by use of purified LIX-65N or by addition of LIX-63. XAD-7 coated with LIX-65N was used in columns. Elution curves for copper showed negligible tailing, and rapid separations of copper from iron (111), nickel, cobalt and magnesium by selective absorption were achieved. Copper was concentrated from very dilute solution at a flow rate of 50 ml min -1 ,and a 99% recovery was obtained. The method was applied to the rapid determination of copper in brass and bronze. A series of long-chain hydroxamic acids were synthesised and tested for suitability as stationary phase on XAD-7. Oleohydroxamic acid and naphthenohydroxamic acid were the most promising. The r ate of uptake of copper was reduced by the use of nonylphenol or amyl alcohol as a diluent. The capacities for copper of the hydroxamic acids were less when supported on XAD-7 than when used as liquid ionexchangers. The distribution coefficients of cobalt, nickel, zinc, lead, vanadium, uranium, iron (111) and copper were measured as a function of pH. XAD-7 coated with oleohydroxamic acid was used in columns for the rapid separation of iron (111) from copper and of copper from nickel, cobalt, lead and zinc. Copper was concentrated from very dilute solution at a flow rate of 45 ml min -1 and a 100,8% recovery was obtained. Copper was successfully separated from nickel by selective elution. The elution curves obtained show negligible tailing. The resin loaded with oleohydroxamic acid lost capacity due to chemical instability. Naphthenohydroxamic acid supported on XAD-7 was not suitable for use in columns, because it was physically unstable.

- Description: Introduction: The macroporous Amberlite XAD resins were coated with LIX-64N and examined for the rate of uptake of copper . XAD-7 was by far the best support and gave a satisfactory rate of uptake up to loadings of 60% (w/w). The specific surface area of XAD-7 was measured by the adsorption of methylene blue from aqueous solution. The area of the wetted resin was five times less than that of the dry resin. LIX-65N was purified and the anti isomer characterised using spectroscopic techniques . The rate of uptake of copper was not improved by use of purified LIX-65N or by addition of LIX-63. XAD-7 coated with LIX-65N was used in columns. Elution curves for copper showed negligible tailing, and rapid separations of copper from iron (111), nickel, cobalt and magnesium by selective absorption were achieved. Copper was concentrated from very dilute solution at a flow rate of 50 ml min -1 ,and a 99% recovery was obtained. The method was applied to the rapid determination of copper in brass and bronze. A series of long-chain hydroxamic acids were synthesised and tested for suitability as stationary phase on XAD-7. Oleohydroxamic acid and naphthenohydroxamic acid were the most promising. The r ate of uptake of copper was reduced by the use of nonylphenol or amyl alcohol as a diluent. The capacities for copper of the hydroxamic acids were less when supported on XAD-7 than when used as liquid ionexchangers. The distribution coefficients of cobalt, nickel, zinc, lead, vanadium, uranium, iron (111) and copper were measured as a function of pH. XAD-7 coated with oleohydroxamic acid was used in columns for the rapid separation of iron (111) from copper and of copper from nickel, cobalt, lead and zinc. Copper was concentrated from very dilute solution at a flow rate of 45 ml min -1 and a 100,8% recovery was obtained. Copper was successfully separated from nickel by selective elution.

- Description: This study is divided into two parts. The first deals with the taxonomy of the South African fishes of the Tripterygiidae. The second part describes the osteology of one genus of the family, and draws comparisons with the other genera discussed in this study. Five genera of Tripterygiidae are recognized from South African waters. Cremnochorites, a monotypic genus, is described as new. The single species, C. capensis, has been recorded only from the southern and south-eastern coast of South Africa. It is distinguished from other genera by a combination of features which includes scalation, dorsal and anal fin spine counts, and various osteological characters. Three genera, Norfolkia Fowler, Helcogramma McCulloch & Waite, and Enneapterygius Rüppell occur throughout most of the Indo-Pacific. A single species of Norfolkia, N. springeri Clark (in press) is found in Zululand. Two species are ascribed to Helcogramma, H. obtusirostre (Klunzinger) and H. fuscopinna sp.n. Parallels are drawn between two species of Tripterygion Risso, T. tripteronotus and T. delaisi from the Mediterranean. The two South African Helcogramma species show similar depth preferences to the two Tripterygion species, resulting in similar morphological differences between the two species of each pair. The genus Enneapterygius Rüppell is divided into two genera, Enneanterygius and Scoliosolen gen.n. The division is based on the form of the supraoccipital sensory canal and associated osteological characters. Sooliosolen has a crescent-shaped supraoccipital canal and cranial osteology similar to the majority of other tripterygiid genera, whereas Enneapterygius has a 'U'-shaped supraoccipital canal which curves around the first dorsal fin, a comparatively long, concave supraoccipital bone which extends anteriorly between the parietal and between the posterior ends of the frontals. Two species are referred to Scoliosolen, S. abeli (Klausewitz) and S. conspicuus (Clark), and two new species are described for Enneapterygius, E. pulcherrimus and E. trianeulus. A literature survey revealed little consistency in ascribing species to any particular genus. Thus, throughout this study an attempt is made to define the genera so that future confusion can be avoided. In the light of these definitions an assessment is made of the original descriptions of a large number of species to determine which of the species can be ascribed to Norfolkia and to Helcogramrna. This has been possible to a lesser degree for Enneapterygius and Scoliosolen, for the major external feature separating these two genera, the shape of the supraoccipital sensory canal, is described only for Red Sea (Clark, in press) and South African species (this study). This study places four species in Enneapterygius, and six in Scoliosolen. To provide a firmer foundation for defining the genera, an investigation was made of the osteology of Scoliosolen conspicuus. Enneapterygius was originally chosen for the osteolofical study as it is reputedly the largest genus of the family, and thus likely to be the most generalized. Once comparisons had been made with other Enneapterygius species, it became apparent that this genus had to be divided into two genera, Enneapterygius and Scoliosolen. It is not known whether Scoliosolen is the largest genus, but it is likely to be one of the largest once a complete survey of the species originally ascribed to Enneapterygius has been undertaken. Finally, an osteological comparison is made of the five genera which occur in South African waters to provide firmer bases for the generic definitions. Only those characters which appear to be constant within a genus are used. Reference is made to a number of genera which do not occur in South African waters, to ensure that the characters chosen cannot be applied to other genera

- Description: It has not been my aim to provide conclusive evidence for or against anyone hypothesis regarding Time and Tense. I have simply attempted to collect together and collate much of what has been written on the topic of tense in English, in order to show what the current trends of thought are. In Chapter One I presented a brief survey of some of the more basic notions associated with time and tense, in order to provide a background for the more linguistic approach to follow. I therefore examined such issues as the difference between time and tense, the problem of the passage and directionality of time, of the present moment, time and space , tense as a universal, "and various features of tense systems. I sketched Bull's system of scalars, vectors and axes as representative of our English tense system. Chapter Two dealt with time and logic, but as I am a mere layman in matters logical, I refrained from discussing any individual logical system in depth, and rather discussed various problems which appear to confront the logician in formulating a tensed or tenseless logic. This chapter aimed at providing a better understanding of the linguistic issues to follow, for time and logic are intimately connected with language. Chapter Three was more linguistically oriented, and in it I attempted to provide a broad outline of the development of thoughts about tense before the Transformationalist period (pre 1960). Because of the vast scope involved, I had, perforce, to be brief at times. I gave attention to tense in classical grammatical studies, and summarized how it was seen from about 1500 to 1800. I gave more detailed treatment to the twentieth century, focussing specifically on grammarians like Jespersen (1933), Twaddell (1960), Ota (1963), Palmer (1965) and others - all, writers typical of the structuralist era. At the end of Chapter Three I provided an overall summary of ideas on the main tenses by the end of the structuralist period - ideas which were to change radically within the next few years. In Chapter Four I discussed the ideas of tense of some of the main transformationalist/generativists - Diver (1964), Crystal (1966), Huddlestone (1968), Gallagher (1970), McCawley (1971) and Seuren (1974), in an attempt to show how theories on tense were becoming increasingly abstract, and how most data indicated that it is highly probable that tense is an abstract higher predicate of the sentence in which it appears in surface structure, closely related to temporal adverbs. Chapter Five continued in the same vein. I tried to show, using syntactic tests, that tense is a higher predicate, and used arguments involving Conjunction Reduction (based on Kiparsky (1968)), VP Constituency, Sequence of Tense, Pronominalization, and Quantification. In Chapter Six I focussed more closely on tense-time adverbials, in order to show that they have the same syntactic properties as tense, are also probably deep superordinate predicates, and are closely related to tense. My suggestion was that either tense is derived from temporal adverbs or vice versa, as this would simplify the grammar. The derivation procedures at the end of the chapter (6.8) were largely based on Hausmann (1971). I made no detailed reference to extralinguistic matters which affect tenses, in this study - such factors as are diScussed by G. Lakoff (1971) (presuppositions and relative well-formedness) and by R. Lakoff (1975). Tense is not a matter of pure Structuralism, just as language is not - extralinguistic factors ought to be accounted for before any study can claim to be conclusive. For this reason I do not in any way claim to have made an exhaustive study of time and tense - I have simply attempted to summarize and coordinate thoughts on the subject, and to suggest tentatively that the most adequate grammar of English would probably derive tense from underlying temporal adverbs.
