- Description: Volcanic rocks are found associated with several of the late Mesozoic basins of southern South Africa. Bentonites are known from Plettenberg Bay and, according to an unconfirmed report, they are also found in the Worcester Basin, while vitric tuffs have been recorded from east of Oudtshoorn. The most extensive occurrences, however, are those of the Suurberg Group, which crops out sporadically around the margins of the Algoa Basin.

- Description: The sudden expulsion of the Xhosa across the Fish River in 1811–12 created a practical and conceptual crisis which the traditional political authorities were unable to resolve. Two commoners, Nxele and Ntsikana, emerged in this vacuum, each proposing his own solution to the problems posed by the white irruption. Although these responses were religious responses, they were neither irrational nor incomprehensible. Xhosa religion had long functioned as an instrument for the control of the material world. By incorporating selected Christian concepts with the Xhosa world-view, Nxele and Ntsikana were able to provide the Xhosa with acceptable explanations of past events and prescriptions for future action. Nxele urged resistance and Ntsikana preached submission, but an examination of their personal histories shows that these final conclusions were more the product of exterior pressure than interior revelation. It may be suggested that the future reputations of the two men, like their past actions, will be determined more by the popular mood than by anything they themselves did or said.

The role of art and the art work itself are inextricably linked. If we look at the role of art as analogous to a wheel we can look at the argument thus : the wheel exists in order to roll. Its function is to roll. The wheel's function of rolling informs us about its existence. Function and the wheel's existence cannot be separated. The role of art and the art work itself are inextricably tied. Intro. p. 1.

- Description: Selected species of two South African rutaceous genera, Agathosma Willd. and Zanthoxylum L., were phytochemically studied. Two species of the former genus, A. puberula (Steud.) Fourc . and A. elavisepala R. A. Dyer, yielded a novel O-prenylcoumarin, puberul in, the structure of which was fully elucidated as 6,8- dimethoxy-7-prenyloxycoumarin. This represents the first report of a coumarin from that endemic genus. In another study the alkaloids in three species of Zanthoxylum, Z. davyi (Verdoorn) Waterm., Z. thorneroftii (Verdoorn) Waterm. and Z. humile (E .A. Bruce) Waterm . , were investigated. Chelerythrine, nitidine, (-) -α-N-methylcanadine, (+)-laurifoline and (+)-magnoflorine were isolated and characterized in the stem and root bark of Z. davyi, while the root bark of Z. thorneroftii contained skimmianine and decarine in addition to the alkaloids present in Z. davyi. Skimmianine, decarine, N-norchelerythrine, chelerythrine, (-)-α-N-methylcanadinc, candicine and tembetarine were identified in the root bark of Z. humile. The chemotaxonomic significance of these alkaloids occurring in the South African taxa in relation to other African Zanthoxylum taxa, is discussed. Several non-alkaloids (lupeol, β-sitosterol and (-)-sesamin) were also isolated and characterized in Z. davyi and Z. humile.

- Description: The Ciskei was gradually ‘consolidated’ by a process of geo-political gerrymandering that included the incorporation of black dormitory townships dependent on ‘white’ cities outside the homeland for survival. By 1973, the Ciskei homeland’s de facto population was estimated at 602 000.4 Since then, the overcrowded rural population has been forced to absorb thousands of refugees removed from South Africa’s ‘white’ areas — including several ‘black spots’ now outside the boundaries of the homeland — and migrants from two districts (Herschel and Glen Grey) formerly in the Ciskei which were ceded by the South African government to Transkei. Any attempt at measuring the extent to which communication affects the political credibility of the present Ciskei homeland in the eyes of its inhabitants must be weighed against these historical realities. This monograph is divided into three parts: 1. An outline of the political system in the Ciskei. 2. The role of the mass media in determining attitudes towards homeland news. 3. Some observations on the status accorded oral channels of communication in the transmission and validation of political news in selected rural and urban areas of the Ciskei. In obtaining data for this study, five surveys were conducted in two rural villages, the biggest urban area in the Ciskei and the Ciskei Legislative Assembly. The villages of Gobozana (or Xengxe) and Nyaniso formed the basis of the rural surveys conducted in April — June 1976. Fifty heads of homesteads in each village, in a universe of about 500 homesteads, were selected at random. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

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.

- 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.

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: 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.

- 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.
