- Description: To the AmaZulu a warthog is "inhlovudawana" or "little elephant"; to arrogant hunters it is the "poor man's rhinoceros"; to some writers of encyclopaediae it is a "grotesque and hideous beast"; to stockmen it has long been a carrier of diseases. Injury was added to insult with the discovery that the blood of these self-assured, often comical and certainly engaging animals supports the greater proportion of tsetse flies in the African savannas. Their significance as the primary hosts of Glossina morsitans Westw., the vectors of tryanosomiasis, justified an extended field study of warthog biology. This thesis reports four years of field work on warthogs, together with complementary observations of hand-reared warthogs (and their offspring) which roamed freely in the vicinity of the remote field station on which I live. The Sengwa Research Project, of which this study forms a part, was initiated in 1965 to study relationships between game animals and tsetse flies. One of the main problems investigated in the Sengwa Project is that of "host encounter" (Glasgow, 1961, Bursell, 1970) and how the distribution, abundance and behaviour of game animals may affect their availability to hungry tsetse flies. I have, accordingly, been concerned with discovering how warthog are dispersed in the Sengwa area and have attempted to gain some understanding of the factors, both environmental and social, which may affect or govern their dispersion and possibly population number. Intro. p. 1.

- Description: Enthusiasm for developing creativity in the individual has been remarkably widespread - at least in America - over the past twenty-five years or so. The armed services, the arts and sciences, educational institutions, businesses and industries are recognising to a greater and greater extent, the urgent necessity of developing this relatively neglected aspect of people is personalities. Their reasons differ, of course, and usually the welfare of the individual himself is not the main concern. This is perhaps fortunate, as advances made on philanthropic grounds alone have never progressed very rapidly. In business and industry, new ideas are urgently needed for survival - this was especially evident after World War II which was, in the end, really a battle of ideas. The importance of this implication has not decreased with distance in time from that conflagration, indeed, individuals in the armed services are probably the people most deeply involved in and the most concerned with the problem of developing creative thought. "We are in a mortal struggle for the survival of our way of life", writes Guilford. "The need (for developing creativity) is a national crisis" says Anderson*. Intro., p. 1.

Developmental studies of certain South African Ascostromatic ascomycetes

- Description: From General Introduction: Toward the last half of the nineteenth century, the structure and mode of development of the ascocarp has aroused much interest. De Bary (1887) recognised the fruiting bodies of the Ascomycetes as 'compound sporophores' made up of interwoven hyphae or of pseudoparenchyma consisting of a peripheral layer separate from an inner tissue. These fruiting bodies included the discocarp or apothecium, the pyrenocarp or perithecium and the cleistocarp or cleistothecium. The name, Pyrenomycetes, has been variously applied to a group of Ascomycetes but mainly to the perithecial types, inclusive of the true perithecia and the loculate forms. The perithecium itself was described as a 'cup-shaped discomycetous' sporocarp with margins incurved to form a pyriform structure (de Bary, 1887). The presence or absence of a stroma had been long considered as a basis for the separation of the major groups of the Ascomycetes. Separation on these grounds was found unacceptable as it grouped together clearly unrelated species or separated related ones. As the subdivisions of the pyrenomycetous Ascomycetes are dependent upon the morphological features of the ascocarp, it would be pertinent to discuss the following: a) The Stroma. b) The various forms of ascocarp which mayor may not be associated with such a stroma. i) Perithecia: free or immersed in a stroma. ii) Uni- or multiloculate stromata. c) The centrum, the details associated with the centrum and the use of these details in the taxonomy of the pyrenomycetes.

- Description: The isolation and structure determination of dubiin and leonitin, two new diterpenoid acetates from Leonotis dubia and Leonotis leonitis respectively, are discussed. The compounds are diterpenoids of the labdane type and are closely related to marrubiin. The proposed structures are based on chemical and spectral evidence. Dubiin, C₂₂H₃₀0₆̕ contains a tertiary hydroxy- group, a furan ring and a ó-lactone while leonitin, C₂₂H₃₀0₇̕ is a γ - dilactone. at C-20. Both compounds are unusual in being oxygenated The extraction of three Euryops species and the isolation of euryopsol, C₂₂H₃₀0₄̕̕ are also described. A furanoeremophilane structure containing three hydroxy- groups, one of which is at a bridgehead position, is proposed. Euryopsol is the first furanoeremophilanoid with a substituent attached at C-IO

- Description: Introduction: Neville Clark has rightly warned against the attempt to approach the theology of the sacraments from a broad and general definition of a 'sacrament' from which we 'read off' a Christian doctrine of the sacraments without paying due regard to the biblical statements. Such an approach could not but obscure the essential differences between the sacraments, and the fact that they stem from historical roots. On the other hand, the specialist treatment of the sacraments which begins by making a detailed analysis of the biblical material fails to do justice to the wholeness of biblical theology and tends to treat the sacraments in isolation not only from each other but also from other aspects of Christian theology with which they are inalienably connected. Bearing in mind the difficulties inherent in both of these approaches, a fresh and more systematic approach is required.

- Description: Writing about Eighteenth Century England, and more particularly about the age of Johnson, Trevelyan gives us an admirable definition of a classical age: It is a "classical age, that is an age of unchallenged assumptions, when the philosophers of the streets such as Dr. Johnson, have ample leisure to moralise on the human scene, in the happy belief that the state of society and the modes of thought to which they are accustomed are not mere passing aspects of an ever shifting kaleidoscope, but permanent habitations, the final outcome of reason and experience. Such an age does not aspire to progress, though it may in fact be progressing; it regards itself not as setting out but as having arrived." To apply this definition of a classical age to the protean Nineteenth Century might, at first glance, seem impossible or at least dangerous. Yet it is only when we see this century - and more particularly the period 1871-1914 - as a truly classical age, as the classical age of the Bourgeoisie, that we can understand the direction and meaning of the revolt during the Twenties and Thirties of which Malraux' work is so representative.

It was therefore decided to confine research to the Documents of the Transvaal and Swaziland District and to write introductory chapters on the period of the early missions. The detailed research for this dissertation begins, therefore, with the creation of the Transvaal and Swaziland District in 1880. The natural point at which to finish appeared, at first, to be the beginning of the Second Transvaal War of Independence, but further research indicated that it would be more useful to conclude with the end of the war in 1902.

This study examines the critical reception Auden received from 1930 to 1960; through a close consideration of a selection of the poems written in this period it will be demonstrated that a considerble discrepency exists between Auden's poetic achievement and. the criticism it received. The main reason for this discrepancy is the lack of attention to individual poems in favour of sweeping surveys of a volume of poetry or the poet's total output. The core of the thesis lies here and the thesis as a whole derives from concern for a poet's reputation during his poetic career.
