  • Description: Description on the back of published version (published in 1982 by Africasouth Paperbacks by David Philip): "Of Chocolates for my wife, first published in 1961 (and 'banned' in South Africa until July 1982), Matshikiza said, "This is a book about real people, many of them my friends, and about a few of the experiences I have share with them." It tells in his own wry, vivacious, coruscating style of black life in the Johannesburg of Orlando, Sophiatown and Alexandra Township when King Kong was in rehearsal - and in sharp contrast to this, of the adventures of the Matshikiza family in London." This book was first published by Hodder & Stoughton, London in 1961.

  • Description: (1) Developments in a.c. conductance techniques during the past ninety years have been reviewed, and a brief outline is given of the older theories regarding electrolytic polarisation. (2) A conductance bridge - incorporating the double heterodyne principle - has been constructed, capable of giving resistance readings to an accuracy of 0.01% over a range of frequencies covering the best part of 100 kc/s. It has also been found possible to calibrate the oscillator so that frequency settings can be guaranteed to an accuracy of , at least, 0.1% in the range: 2 kc/S to 50 kc/S. (3) The Wheatstone Bridge Network has been slightly modified to enable measurements at the high frequencies. (4) Resistances in the measuring arm of the bridge have been calibrated 'in situ' by the method of intercomparison. (5) A brief description is given of the modern theories regarding electrode processes and modern methods of eliminating electrode effects. (6) Two types of conductance cells, with bright Pt electrodes, have been used to carry out measurements on potassium chloride solutions: (a) Thomas- Gledhill Cell (b) Nichol-Fuoss Cell. The latter incorporates concentric, cylindrical electrodes with the lead to the outer electrode acting as an electrical shield for the lead to the inner electrode. This cell was constructed and used for the first time in this laboratory. (7) From resistance-frequency graphs plotted, it is shown that the Jones and Christian extrapolation procedure cannot be applied (with any degree of confidence) to obtain the true resistance, when measurements are effected over an extended range of frequencies. (8) The method of resistance-reactance diagrams is discussed and applied to various networks of resistances and capacitances. (9) By drawing resistance-reactance diagrams for the experimental readings obtained, equivalent circuits have been derived - for all the solutions investigated in the N-F cell, and for the approx. O.OlD solution in the T-G cell - which approximate to cell behaviour in the range: 500 c/s to 75 kc/s. The less concentrated solutions in the T-G cell show peculiar behaviour at the high frequencies. (10) Probable reasons are advanced for deviations from linearity on resistance-frequency graphs. (11) A new method is proposed for determining the true resistance of solutions measured in cells of the N-F type. Summary, p. 166-167.

  • Description: These fishes are generally assigned to the family Serranidae, one of the most diverse and cumbersome groups of fishes. Containing numerous ill-assorted types this family for convenience at least merits sub-division. One of the natural sub-groups, generally given sub-family status as the Anthiinae, but here given full family rank, consists mainly of small, brilliant, free-swimming coral haunting types confined almost exclusively to tropical seas. These d iffer from the Serranidae proper in the absence of a supramaxilla, in having larger scales, in the dentition, and mostly in the concave or lunate caudal. Although by most workers assigned without question to the Serranidae (sensustricto) the monotypic genus Variola Swainson, 1839 has distinct affinities with the Anthiidae. The dentition, lunate caudal and the brilliant colouration accord better with the Anthiid than with the Serranid fishes. , Rhodes University Libraries (Digitisation)

  • Description: Fishes of the family Apogonidae of the Western Indian Ocean and the Red Sea. Small and relatively feeble as most of these fishes are many cover an astonishing range. Some are found over truly vast areas of the Indo-Pacific, ranging from Southern Africa to the mid-Pacific. As a result, workers on even mid-Pacific Apogonidae need to give heed to the fauna of the Red Sea and of the Western Indian Ocean, from where, as in the case of the Parrot fishes, many early types were described. Failure to do this has caused species from the Pacific described as new, later to be proved identical with those long known from the Red Sea or the Indian Ocean. , Rhodes University Libraries (Digitisation)

  • Description: As is w ell know n, there is a sharp line of distinction at the Cape between the warmer waters of the east and south coast of Africa, and the cool seas of the western Cape areas, with corresponding cleavage in the marine fauna. It was in this cooler area that a specimen of the first member of this group, Xenopoclinus kochi Smith, 1947, was discovered, and at that time it was given subfamily rank in the Clinidae. Until recently only the holotype was known, but now not only have further specimens been secured, but also a second species in this genus, and even more striking is the discovery of a second genus and a third species from the same locality. These forms all show clear relationship with the Blennioid fishes, but despite the numerous families in that order, I cannot find any among them that are so clearly related to the fishes described here, as to be able to assign this small group with certainty to anyone. The peculiar characters appear to merit full family rank, as is given here. , Rhodes University Libraries (Digitisation)

  • Description: This investigation is concerned with primary variations in the silver content of gold which occurs in hydrothermal deposits, particularly those of hypothermal character which are found in Basement rocks in Southern Rhodesia. The nature of the gold produced by a number of different mines has been studied by reference to production data, and microscope techniques as well as gold and silver assays have been used to determine and to explain the variations in gold fineness. The literature does not contain a great deal of information which is relevant to this topic, but an attempt has been made here to summarize the more important contributions by different writers. From this it emerges that the interpretations given by different investigators are in conflict and that paradoxes may arise when efforts are made to explain observed variations in fineness in terms of certain generalizations which have become entrenched in the literaure. In particular, it is shown that falling temperature alone cannot account for the occurrence of silver-rich gold in certain deposits. The Gwanda district of Southern Rhodesia has been selected as a typical gold belt, and the variation in fineness in 150 producers is described. The deposits are hypothermal in character, and the average fineness of the gold is high but variable, but in a small proportion the fineness is low. It is shown that the nature of the host rock and the distance of a deposit from the granite contact appear to have no influence on the fineness of the gold and that there is no zonal arrangement of fineness values. There is a suggestion that diversity of mineral species in any particular area may be accompanied by rather wide fluctuations in the gold fineness. The variations of fineness in eight typical Southern Rhodesian deposits are studied in detail, by analysis of production data, by assaying specimens of the ore and by the examination of polished specimens of gold-bearing ore. Briefer reference is made to two other deposits in the territory, and to deposits in other countries which appear to bear out the conclusions reached in this section. It emerges that there are two factors which can commonly be correlated with variations in fineness. The first of these is the grade of the ore: high-grade ore generally contains purer gold than low-grade ore. Secondly, the textural evidence indicates that gold which separates relatively early in the paragenesis contains more silver than that which is deposited in the final stages of metallization. A general survey which draws on the literature as well as on the writer's examinations of deposits in the territory indicates that, in general, gold which is associated with late-stage minerals such as tellurides, antimony, bismuth and bismuthinite is silver-poor. Gold associated with galena may be either silver-rich or silver-poor, whereas gold which is of the same age as chalcopyrite or sphalerite is very frequently rich in silver. The difficulty which is encountered in establishing the age of gold which is intimately associated with pyrite and arsenopyrite renders uncertain the correlation between fineness and age of gold in these latter cases. There are, however, indications that gold which is truly contemporaneous with either pyrite or arsenopyrite is silver-rich. In the discussion, the objections to the common practice of singling out temperature as the most potent factor controlling gold fineness are listed. Chief amongst these objections is the fact that gold does not in all deposits increase in fineness with increasing depth: examples are quoted where fineness was found to decrease as deeper levels of the ore body were exploited. It is shown that there is no consistent relationship between the size of gold grains and their silver content. It is the writer's conclusion that in hydrothermal deposits in this territory the high fineness of the gold is due to increasing solubility of silver in the ore fluids in the late states, and that where hydrothermal deposits are characterized by gold with low average fineness, an unusually large proportion of the gold has been deposited early in the paragenotic sequence. In the majority of hypothermal deposits, however, the bulk of tho gold separates late in the sequence and the fineness is accordingly high. It is believed that the relationship which exists between fineness and tenor in many deposits is due to protracted crystallization of gold in those portions of the ore body which remained permeable to the latest stages. These portions of the ore body, which represent either valuable ore shoots or ore shoots in miniature, are likely to contain gold of variable character, but the average silver content will be low because a large proportion of the gold is "late" gold. The factors which might cause epithermal gold to have a lower fineness than mesothermal or hypothermal gold are briefly discussed. Some possible applications of this study are indicated in the final chapter. It is claimed that records of gold fineness might constitute a valuable addition to mill records. Tentative suggestions are made regarding a method whereby the approaching exhaustion of a deposit might in some cases be predicted. With regard to the origin of the gold in the Witwatersrand sediments, it is pointed out that the modified placer hypothesis is not fully equipped to explain certain of the variations in the composition of the gold.
