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: 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: A plug-like intrusion of Karroo dolerite, near Dordrecht in the Eastern Cape of the Republic, is described. Field mapping with the, aid of aerial photographs has revealed that the contact of the intrusion, for the most part, dips very steeply outwards. In the south- eastern and eastern areas, however, sheet- or sill-like forms appear to be given off from the main intrusion. In plan view the intrusion is roughly oval shaped, its longer axis being aligned in a north-westerly direction. Its surface area measures approximately 60 square kilometres (24 square miles). A large number of xenoliths composed exclusively of Stormberg sediments, pyroclastic rocks and minor lavas, are to be found cropping out within the dolerite intrusion. These xenoliths, many of which occur in positions far above or below their normal stratigraphic elevation, are extremely variable in size - the largest having an area of approximately 15 square kilometres (6 square miles). The xenoliths represent fragments of the original "roof" of sediments and pyroclastics which have collapsed into and been engulfed by the dolerite magma. This type of dolerite intrusion is known as a "belljar" intrusion. A superficial classification of the dolerites, based chiefly on textural and certain mineralogical features, is presented. In the area surrounding the main intrusion are a number of dolerite dikes and sheets. The youngest phase of igneous activity is represented by the Dragon's Back dike, which cuts across the complex in a north-westerly direction. Several veining phenomena, as well as an interesting variety of metamorphic and metasomatic rocks, are associated with the main dolerite intrusion. Six diatremes are situated in the vicinity of the intrusion. Pyroclastic rocks are represented by a variety of types, and are to be found outside the area of the intrusion, and as xenoliths within it. A tentative interpretation of the mechanism of formation of the intrusion, which appears to be related to volcanic activity and cauldron subsidence, is presented.

Description: From Preface: As a teacher with experience in competitive sport, the author became interested in the topic of athletic competition when joining the staff of an all-boys' school. The competitive aspect of sport at such a school can make quite an impression on an inexperienced teacher. The question then arose; Is this competitive atmosphere universal? Is this type of competition acceptable and desirable in our schools? Being a teacher of Physical Education as well as other subjects and also being actively involved in the coaching of senior sports teams the author regarded himself suitably qualified to investigate the matter of athletic competition in our schools.

Description: From Introduction: That bilharziasis an important public health, social and economic problem in the tropical and subtropical countries of the world is well appreciated. (WHO, 1965) Bilharsiasis is the disease caused by parasitic worms of the genus Schistosoma having certain fresh water snails as the intermediate host. In South Africa the more important snails are Bulinus africanus and B. globosus, the secondary hosts of Schistosom haematobium. (WHO, 1965) One method of controling the disease is to reduce the numbers of the intermediate host snails to such a low level that transmission cannot occur (WHO, 1965 and Macdonald, 1965) This has led to a strong interest in those substances that kill snails. The first recorded use of a molluscicide, copper sulphate, was during the first world War in Egypt. (De Villiers, 1965) More recently, the more or less random testing of large numbers of compounds led to the discovery of a large number of molluscicides. These were the heavy metal compounds such as the salts of mercury and arsenic, the substituted phenols such as pentachlorophenol (PCP) and the 2-substituted 4:6-dinitrophenols. (De Villiers, 1965) These compounds are good molluscicides but suffer from a number of disadvantages. The use of copper compounds in hard waters is impractical as the copper precipitates out as the less effective carbonate. The heavy metal salts are expensive and biocidal thus making the treated water unsuitable for human or agricultural use. The phenolic compounds are unpleasant and dangerous to handle and the hydrolysis of PCP is catalysed by sunlight in clear waters. High concentrations of these compounds are required, thus increasing transport and handling costs, particularly in inaccessible areas.

Effects of vigilance decrement on the recognition of embedded figures

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.

Description: Maurice was a man who solicited both keen support and bitter opposition, both during his life time and after. It is only within the last twenty or thirty years that his true worth has begun to be recognised and appreciated. The aim of the thesis is to show that his contribution to the Christian Socialist Movement was an invaluable one. Chapter two describes the working-class conditions and their causes during the first half of the nineteenth century, as well as the role the Church played in social improvement. Chapter three deals with Chartism and the European Revolutions of 1848, and the effect of the Revolutions on Chartism. Chapter four gives an account of the man F.D. Maurice, as well as some of his thoughts and aims. Chapter five is a detailed account of Maurice's contribution to Christian Socialism, showing that he was not the 'practical' leader, and emphasising the importance of his theological beliefs in governing what to do.

Description: From Preface: A preliminary survey of the history of the Wesleyan Methodist Church in the Transvaal revealed that the period of the early missions, before the formation of the Transvaal and Swaziland District, required research into the documents of other Districts for the purpose of writing a detailed history. 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.

Description: From Introduction: Frederick Denison Maurice is generally remembered in connection with the rise of Christian Socialism. That his activities in this Movement were the most important aspect of his career is doubtful. ... Maurice's fundamental theological principles were: first, the idea of unity - unity in the Godhead, "Unity in Trinity", and unity among men in the human family; secondly, the Fatherhood of God - a Fatherhood which had at its heart the principle of sacrificial love. The events of Maurice's life proved to be fertile ground for the growth of these convictions. It was these convictions which shaped his whole understanding of the Atonement. Davies (3) points out that, in his teaching on the Atonement, Maurice turned away from the Western and Augustinian insistence that the basis of man's relationship to God was the Fall, and held, with the theolo Gians of the Eastern Church, that Christ's redemption of man is best understood as a restoration of man's relationship to God in Creation.

An investigation into religious instruction in state high schools in the Cape Province

Description: From Preface: The question of religious instruction in Cape Schools first aroused my interest when I was subjected to anything but religious tnstruction during my own high school years. My desire to enquire into the whole position of religious instruction in the high school curriculum grew out of an essay on the role of religion in the education of the child which I wrote whilst reading for the B.Ed. degree. As background, I read Harold Loukes' classic Teenage Religion, and from then onwards, I felt that it was necessary to undertake an investigation of this kind in the Cape Province. My aim was not only prompted out of a desire to expose what I already knew to be an educationally and religiously unsound and unhealthy state of affairs, but more deeply because I, although an ignorant amateur in theology, am aware that too often the traditional religious foundations, poorly built by unintelligent teaching, are shaken, if not destroyed, by scientific discovery and material advancement.

A contribution to the biology of warthog (Phacochoerus africanus, Gmelin) in the Sengwa region of Rhodesia

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.
