- Description: Using an experimental pressure chamber the rates of descent and the maximum depths of buoyancy equilibrium of some cichlid fishes were tested. Tilapia mossambica juveniles could descend to depths greater than 30 metres very rapidly. At 22°C small sub adult male fish (length ± 160 mm) could descend to a maximum buoyancy depth of 20 metres, small sub adult females to 13 metres while large adults (length ± 200 mm) of both sexes could descend to 11 metres. The fish generally take 4 to 5 days to reach their maximum equilibration depth. At 30°C mature adult male and female T.mossambica increased their maximum equilibration depth to 20 metres and at 15°C showed a decrease to a maximum depth of 6.7 metres. Temperature affects the rates of descent in a similar manner. T.rendalli can descend to 7.5 metres at 22°C. T.sparmanii can descend to 15 metres at 22°C. Hemihaplochromis philander fry and young juveniles are not affected by pressure. Adult males can descend to 16 metres at 22°C and 20 metres at 30°C. Adult females can descend to 26 metres at 22°C and 27 metres at 30°C. In T.mossambica oxygen appears to be the only gas secreted into the swimbladder to compensate for buoyancy loss. The haemoglobin of T.mossambica showed a marked Bohr and Root effect. Increased rates of descent with increased temperature are believed to be due to increased O₂ uptake, heart output etc. rather than as a direct effect of blood chemistry. The swimbladder wall of T.mossambica is extremely thin (2.8 ∕∪ m) and consequently a large amount of gas is lost through passive diffusion. Diffusion is not affected by temperature, consequently the increased secretory rates at higher temperatures are not balanced by a proportionately higher diffusion loss, thus enabling the fish to maintain a deeper buoyancy equilibrium at higher temperatures. Summary, p. 62-63.

- Description: From Introductory note: The Complete Poems of W.H. Davies (London: Jonathan Cape, 1963; rev. 1968) has been used throughout this study. Accordingly, unless otherwise stated, all citations of poem numbers and pagination refer to this text. Critical literature on the work of W.H. Davies is restricted in quantity and limited in scope. There are few comprehensive assessments of Davies as poet, autobiographer, novelist, or raconteur. Apart from such sources as Richard J. Stonesifer's full-length critical biography (1963), Lawrence Hockey's biographical monograph (1971), and Thomas Moult's anecdotal and historical appreciation (1934), critical material must be drawn from contemporary reviews, isolated articles in magazines such as The Catholic World and Fortnightly Review, and specific chapters in surveys of the poetry of the early twentieth century, although Davies is frequently alluded to passim in literary histories which deal with this period. Many of these studies favour biographical exposition and evaluation rather than descriptive analysis and discursive interpretation. A detailed chronology of Davies's works is included in Stonesifer's discussion. This thesis is not attempting to trace a line of development for two reasons. First, the Complete Poems gives no indication of date of composition or publication of particular poems, and the present writer has access only to the dates of publication of individual volumes as external evidence of a chronology, internal evidence being confined to such infrequent references as "the birds of steel" in Poem no. 236, p. 260. Secondly, the lyrics themselves do not, on the whole, evince much stylistic and thematic development, and the concern of this study is with recurrent themes and techniques dispersed throughout the oeuvre.

- Description: Poetry, like every other form of art, reflects the values of the artist himself as well as the values of the age in which he lives. "I would say that the poet may write about anything provided that the thing matters to him to start with, for then it will bring with it into the poem the intellectual or moral significance which it has for him in life". (Louis MacNeice). This thesis sets out to uncover some of the things which, in the long pageant of English poetry, have "mattered" to poets to such an extent that they have felt compelled to voice their protest against any violation of such things perceived by them in life around them. The basic study has been a search for the different kinds of values and codes of conduct, in social, political and moral spheres, which have been unacceptable to some of the major poets in English, and to examine particularly the manner and the tone of voice in which each one has expressed his disapproval. "Poetry was the mental rattle that awakened the attention of intellect in the infancy of civil society." (T.L.Peacock). English poets who have protested against whatever they regarded as worthy of protest have continued up to the maturity of civil society to be rattles (some soft and mellow, others loud and harsh), to awaken both the intellect and the conscience of their readers.

A comparative developmental study of the fear of snakes

- Description: This study was conducted to determine the influence of age and culture on the fear of snakes. Five age groups, consisting of 20 White and 20 Xhosa subjects each, were tested. In addition to a behavioural and a GSR measure of fear, questionnaires were applied to determine the extent of the subjects' personal and vicarious aversive experiences of snakes and attitudes towards snakes. The behavioural measure showed a significant decrease in the fear of snakes between the 9 - 11 year and the 14 - 16 year White groups, while, for the Xhosa subjects, the fear of snakes increased significantly between the age groups 14 - 16 years and 18 - 20 years. The GSR measure showed a consistent level in the fear of snakes for White subjects. For the Xhosa subjects the mean GSR score for the 18 - 20 year .group was considerably higher than the means for the other age groups. The intensity of the fear of snakes for White and Xhosa subjects of the same age was remarkably similar. Xhosa subjects had significantly more negative attitudes towards snakes than white subjects. This finding was explained in terms of Whites having had greater opportunities to obtain factual information about snakes. No significant relationships were found between (a) the measures of the extent of the subjects' aversive experiences of snakes; (b) the degree of negative attitudes towards snakes; and the measures of the fear of snakes. On the basis of these measures, the etiology of the fear of snakes cannot be explained in terms of aversive experiences with snakes per se. The striking similarity of responses to a live snake by subjects from two widely different cultures suggests caution in an over-hasty dismissal of the theory of an innate fear of snakes.

These preparations have a great reputation in curing diseases of the kidney and urinary tract, and in addition are employed as local applications to bruises, and for the relief of rheumatic pains. We owe its introduction into medicine to the Hottentot, who gave the name "buchu" or "bookoo" to any aromatic herb or shrub which they found suitable for use as a dusting powder.

- Description: An interest in colonial literature is relatively new in the study of English. English-speaking South Africans especially, cut off as they are, a minority group in a new republic, have begun to re-assess their identity through a study of their existing literature. When asked what South African verse there was beside his own, Kipling remarked, "As to South African verse, it's a case of there's Pringle, and there's Pringle, and after that one must hunt the local papers." This thesis is the result of such a hunt - the hunt being limited to the years 1824 to 1851 - and on occasion, the writer has been tempted to conclude rather unfairly, "And there is only Pringle." It cannot be claimed that every poem ever printed during the period under review has been collected and examined, for the reason that many volumes of old newspapers are no longer available. Nevertheless, it has been possible to make a representative selection, which could provide the raw material for several theses to come. A detailed study of critical criteria prevalent at the Cape during this period, or public taste and the influence especially of the lesser British poets are some of the topics which might repay study. Intro., p. 1.

More than one head prefect that I have known has appeared to fade into anonymity after apparently leading his peers at school. I wondered if this was perhaps because at school he was not really a leader but simply an efficient policeman. Conversely, people who were not prefects at school often appeared as leaders in their chosen post-school careers. It seemed as if for some reason the prefect system at the schools concerned did not appreciably aid many pupils to develop their leadership potential or the selection procedures were inefficient. On investigating further I became more and. more interested in this topic until eventually, on discovering that the Rhodes University Education Department had a set of leadership scores, (calculated from a personality test) I undertook this investigation.

- Description: This work encompasses an inquiry into the role of the entrepreneur in economic development, and a report of interviews with eighty African businessmen in the Transkei, Ciskei and some urban locations. South Africa provides a particularly interesting field for the study of African enterprise insofar as it is possible to examine the evolution of entrepreneurship in two fundamentally different environments - namely rural reserves and large urban areas. Furthermore, there has been a substantial increase in the number of African entrepreneurs during this century. The study achieves added significance in view of the wide racial income differentials which are an endemic feature of South African socio-economic existence; moreover, there is a great deal of evidence to suggest that, despite the high real growth rates during recent years, the racial income gap is widening. A corollary to this is the worsening of the relative - though not necessarily the absolute - economic position of the Black population.

Information indicative of the extreme racial inequality of property ownership in South Africa is given by Spandau, who has shown that in 1960 'other income' (i. e. rent, interest and profits) formed 119% of work income of Whites, and only 19% of the work income of Africans. 2 In the absence of cataclysmic social change, the development of African entrepreneurial talent emerges as a possible means of escaping from this apparent impasse. This does not of course imply that even a fairly large increase in the number of African entrepreneurs would automatically result in raising the living standards of a substantial portion of the Black population. Nevertheless, it would represent a positive move towards redressing the inequalities in property ownership and facilitate the acquisition of organizational skills, which in turn implies a better utilization of human resources than exists at present.

- Description: This work encompasses an inquiry into the role of the entrepreneur in economic development, and a report of interviews with eighty African businessmen in the Transkei, Ciskei and some urban locations. South Africa provides a particularly interesting field for the study of African enterprise insofar as it is possible to examine the evolution of entrepreneurship in two fundamentally different environments - namely rural reserves and large urban areas. Furthermore, there has been a substantial increase in the number of African entrepreneurs during this century. The study achieves added significance in view of the wide racial income differentials which are an endemic feature of South African socio-economic existence; moreover, there is a great deal of evidence to suggest that, despite the high real growth rates during recent years, the racial income gap is widening. A corollary to this is the worsening of the relative - though not necessarily the absolute - economic position of the Black population. Hence : "the fundamental question for South Africa's economic future revolves around the income relationship between the Whites and the African segment of the non- White group." At present a great deal of pressure is being exerted on White employers to adopt more racially equitable systems of remuneration, and on the Government to relax the industrial colour bar.

- Description: A brief account of the location and physical aspects of the region is followed by descriptions of mapping and laboratory techniques employed. Recent ideas on regional stratigraphical correlation in South West Africa are critically reviewed. Strata lying southeast of the farm Losberg 105 have, on the basis of lithology and copper mineralisation, been correlated with the Tsumis Formation. The Hasib Formation, of predominantly marine character, has on structural grounds been excluded from the Damara System. The latter here has a greater thickness than elsewhere in South West Africa, unless isoclinal folding is much more prevalent than has been assumed. The occurrence on Eintracht 118 of a pebble conglomerate, tentatively equated with the Chuos Tillite, makes possible a subdivision of the Damara strata into the various series established in the literature. It has been found possible to differentiate between Kamtsas and Damara quartzites on petrological grounds. Further, it is concluded that the bulk of Hakos carbonate rocks originated as dolomites and have subsequently been dedolomitized to a greater or lesser extent. The area contains both ortho- and para-amphibolites, as well as one occurrence of intrusive granite. Evidence is given for at least three periods of deformation. It is oonsidered that, if the Hosib Formation was involved in a pre-Damara orogenic episode, later folding must have been co-axial with this. Sedimentation and metamorphism are treated in broad outline. There appears to have been a deepening of the basin of deposition from Hasib to Damara times. Cyclicity in sedimentation is evidenced by lithological associations in the Damara strata. The entire area falls into the greenschist facies of regional metamorphism. Superficial deposits include river gravel and, silt, quartzite- and vein quartz-rubble, calcrete and Kalahari sand. The economic geology is described with special reference to the widespread copper mineralisation.

- Description: The geology of the Shamrocke area is described relative to its regional setting and position within the stratigraphic succession of the Lomagundi System. The stratigraphy in the immediate vicinity of the Shamrocke Mine is detailed and discussed relative to the work of others south of the project area and in other regions. The petrography of the rocks of the Shamrocke Mine area is described and the results of a great deal of mineralogical work recorded. Maps of the project area are presented at various scales from field and photogeological evidence. The thesis area is situated on the South Zambezi Escarpment of Rhodesia, and the geology described included the basaI succession of the Lomagundi System and the pre-Lomagundi Escarpment Series. The Shamrocke Mine is located on a copper orebody associated with a granulite or granofels zone within the Dolomite Series of the Lomagundi System. This ore zone granulite appears to be a metasomatised calcareous grit some 1000 feet above the upper contact of the Deweras Series (basal Lomagundi) and, within the graphitic schist and phyllite, below a dolomitic horizon in the Dolomite Series. The Lomagundi succession in the Mine area unconformably overlies the pre-Lomagundi gneiss and meta-arkose of the older, metamorphosed and deformed Escarpment Series. The basal meta-arkose, meta-quartzite and coarse schist of the Deweras Series ascends southwards through the Dolomite Series (graphitic phyllite and schist, granulite, calcareous grit, dolomite, limestone), and the Argillaceous Series (schist, phyllite, quartzite), the beds dipping steeply to the south at an angle of between 50º and 70º. Post-Lomagundi plagioclase amphibolite (altered, intrusive meta-diabase) forms Iarge semi-concordant and transgressive sills throughout the area, particularly along the contact between the Deweras and Dolomite Series. The Shamrocke Mine is on the northern limb of a large synclinal structure, the Rusere Syncline, which forms a large embayment of Lomagundi rocks into the pre-Lomagundi gneisses and granodiorites northeast from the Mine. The fold is overturned to the east and southeast. The copper mineralisation within the area and in the areas to the south is considered to be invariably associated with the basal rocks of the Lomagundi System. It occurs within both the Deweras and Dolomite Series rocks and more often than not Iies close to the contact between these two Series. The sulphide mineralisation of the Shamrocke orebody is considered, from the results of the present study, to be metasomatically emplaced during carbonate metasomatism, either from an extraneous source or from within the ore zone rock itself. The present writer favours the origin of the copper sulphide to be original syngenetic sulphide of the basal rocks of the Lomagundi depository, which has been mobilised and metasomatically relocated, possibly by the effects of regional metamorphism related to intense deformation. It is perhaps not fortuitous that the majority of the copper occurrences in the area occur where the basaI beds of the succession have been cross-folded. The copper ore comprises a simple suite of minerals, the main constituents being chalcopyrite, cubanite and pyrrhotite. The deposit is compared relative to the other copper deposits of the Lomagundi System.

- Description: The two point threshold was studied extensively by the psychophysical experimenters of the last century. More recent formulations in signal detection theory have suggested that the statements of these workers about absolute thresholds should be viewed with caution. This study investigates the two point threshold in the light of these formulations, and has two main aims :- (1) To state and deal with the problem of relating a limitation in perceptual ability, such as that which is represented by the two point threshold, to the receptor organisation of the body. (2) To demonstrate a practice effect on the two point threshold, and to consider this in the light of (1) above. To fulfil these two aims, a model of the neural mechanisms underlying the discrimination of two points applied to the skin is proposed, and this is able to accommodate what is known of the two point threshold. Although the model is simple it explicitly accounts for size transfer and the practice effect, and provides some clues as to the type of neural mechanism capable of producing them. The practice effect is demonstrated experimentally, and the results are then referred to the model proposed. The physiology of an organism sets the limits for its behaviour. 'The first aim is thus an important one, in that it considers a specific case of this general problem. And secondly, the practice effect on the two point threshold is typical of a number of fairly simple "learning" phenomena, which are part of the psychologists' study of learning.

- Description: "Ticks have already been studied in our country and abroad. Progress in the field of taxonomy has probably been the most rapid and has culminated in a large number of papers and excellent monographs, but much more remains to be done. To produce an overall picture of the factors influencing the behaviour of the tick under natural conditions, studies have to be conducted on tick ecology and experimental physiology. We still have a lack of knowledge of host specificity, the selection of feeding sites on hosts and the nature of resistance to attacks by ticks. Because of the varied habits of different species of ticks, the first essential prerequisite is an adequate knowledge of their biology." (Jansen 1969). The above words sum up the position of research on ticks in southern Africa at the present time.

- Description: "Ticks have already been studied in our country and abroad. Progress in the field of taxonomy has probably been the most rapid and has culminated in a large number of papers and excellent monographs, but much more remains to be done. To produce an overall picture of the factors influencing the behaviour of the tick under natural conditions, studies have to be conducted on tick ecology and experimental physiology. We still have a lack of knowledge of host specificity, the selection of feeding sites on hosts and the nature of resistance to attacks by ticks. Because of the varied habits of different species of ticks, the first essential prerequisite is an adequate knowledge of their biology." (Jansen 1969). The above words sum up the position of research on ticks in southern Africa at the present time.

- Description: Field independence was described by Witkin et al (1962) as the ability to separate an item perceived from its context. Here most experiments have used visually presented material where the subject was shown a simple geometrical figure and then a complex one containing the simple figure as part of it: the subject's task was to find and point out where the simple figure was hidden. Recent work has suggested that the skills involved in Witkin's tests might be associated with particular cultural backgrounds. This extension of Witkin's theory of field independence by Wober linked visual phenomena with those of a social and maturational nature: the ability to separate visual items from their context was shown to be aligned with the development of a sense of personal identity ; the person was considered to be an item set in a context or social field, be it family or society around him: an individual, depending on the way he was socialized as a child, may perceive the world analytically, if he did he was labelled field independent, if not he was field dependent. Intro. p.1.
