- Description: From Introduction: The use of chemical molluscicides in the control of schistosome transmitting snails has been largely based on empirical studies of toxicity, rather than on a clear understanding of basic physiology and biochemistry of snail hosts. It is therefore possible that purely physiological studies may in themselves provide information which could be of value in the development of more effective mollucicides. In this investigation an attempt has been made to understand some aspects of the respiratory physiology of three species of fresh-water pulmonate snails, all of which are of medical and veterinary importance in the Republic of South Africa. Bulinus (Physopsis) africanus (Krauss) is the intermediate host of Schistosoma haematobium, the causative organism of human schistosomiasis (Bilharziasis). Bulinus (Bulinus) tropicus (Krauss) is the intermediate host of the conical flukes Calicophoron calicophorum and Paramphistomum microbothrium and of the liver fluke Fasciola hepatica, while Lymnaea natalensis Krauss is the intermediate host of the liver fluke Fasciola gigantica.

- Description: In the early 1950’s the area of the eastern Cape Province adjoining the Transkei was the object of an intensive study known as the Border Regional Survey and five volumes have already been published. This work is a more detailed investigation of one aspect of the economy, namely the growth of manufacturing industry. Its importance lies in the fact that not only is the African population increasing rapidly, but that effective rehabilitation of peasant farming in the Transkei and Ciskei must necessarily displace large numbers from the land. Expansion of manufacturing industry would appear to be the most effective means of providing remunerative employment for these people, Moreover, the government has embarked upon a policy of encouraging the establishment of factories on the periphery of the Bantu areas, and the eastern Cape is an important area in this general scheme. It may well be the most crucial testing point of the whole policy of border industries', because with its large Transkeian hinterland it is the area most in need of expanding employment opportunities; but, at the same time, by reason of locational and other disabilities, it is the area in which industrial expansion may be most difficult to achieve. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: From Preface: In this age of ecumenical discussion it has becone necessary for all Christian communions to examine afresh their traditional beliefs. This has frequently led to restatement and reformulation of such traditional beliefs. It has also driven us back to seek new light from the Biblical sources. It seemed that such a re-examination of the traditional doctrine of the priesthood of all believers was necessary so that those who claim to hold it know what they hold, and so that those who do not may know what it is that their fellow-Christians believe, and why. This was the first reason for this study.

Proportional distribution of predominant rumen bacteria between the solid and the liquid portions of ruminal ingesta

- Description: That certain bacteria in the rumen of sheep and cattle are attached to solid particles in the ruminal ingesta has been known for many years. In 1942 Baker published direct microscopical evidence that bacteria were attached to cellulose food particles and to starch granules in the rumen. The sites of attachment of these bacteria corresponded to sites of disintegration of the particles when viewed by polarised light. This indicated that at least bacteria attacking solid substrates such as cellulose and starch were attached to particles of ruminal ingesta. Van der Wath (1942) found rumen bacteria attached to particles of chemically pure cellulose and of crushed maize which he suspended in separate compartments of a pure silk bag inside the rumen of sheep. The bacteria associated with the particles of cellulose were mainly Gram negative rods , while clusters of iodophilic cocci were observed in most instances around the maize kernels . The latter organisms were isolated in pure culture and found to be heat-tolerant, short-chain, Gram positive cocci fermenting glucose, maltose, and other soluble sugars as well as starch. It was thus not surprising that many years later Schwartz et al (1964) obtained evidence which suggested that bacteria metabolising soluble substrates such as glucose also showed marked attachment to solid particles of ingesta.

A study of irradiation effects in solids

- Description: One of the primary objects of this research was to determine, if possible, the nature of the radiation damage prior to thermal decomposition. The X-ray study has not wholly achieved this although more information has been derived from it than from similar work on AgMnO₄ However, the diffuse reflections obtained do indicate, quite strongly, the creation of point defects during irradiation. This is of value since such assumptions have been made in the explanation of the kinetics of decomposition of a number of irradiated solids (BaN₆,CaN₆). In addition the X-ray work has suggested future research which should produce useful information; namely, a precise study of the diffuse reflections. Another object of the research was to attempt to determine what characteristics, if any, of the kinetics of the decomposition of an unirradiated solid would predetermine a marked irradiation effect. It is obvious that the type of nuclear growth which occurs e.g. branching chain, or power law, does not characterise a substance with regard to a possible irradiation effect . The photosensitivity, or otherwise, also does not determine whether there will be an irradiation effect. However, the one property that the substances which have been studied, have in common, is a polyatomic anion, but here again ammonium dichromate does not show an acceleration of the decomposition after irradiation. Consequently it is considered that it is not possible to say, a priori, whether a solid will undergo an accelerated decomposition after irradiation. Each new solid, unless it belongs to a particular class e.g. the alkaline earth azides , must be considered afresh. Nevertheless it does appear that the irradiation effect can take two forms: - (i) the production of an unstable compound e.g. nickel oxalate, the decomposition of which affects the normal pyrolysis; and (ii) the production of point defects which determine the nature of the subsequent thermal decomposition e.g . CaN₆ . It is possible that the effect requires an interaction of the created point defects with the existing line defects.

- Description: [From Preface].

The immemorial figure of the Wandering Jew, to cite a sIngle instance, has for the past two decades, attained his country and place of destination - history no longer condemning him to tarry until the Second Coming of the Messiah. Even the deicide Jew has been granted complete absolution, by an offlcial decree from the Vatican, for his complicity in the killing of Christ. It would seem, moreover, that the atrocities perpetrated against the Jews during the course of the Second World War have resulted in an alteration of the Jewish image radically transforming It from one of contempt into one of compassion a living symbol of "man's inhumanlty to man"; and the modern European dramatist has revived the Jewlsh figure on the stage as an instance of almost personal atonement or, alternatively, as a means of scourging the state of middle-class mind which abetted the persecution of the Nazi regime, attacking state policies of inactio and deploring the failure of influentlal powers to resist the blatant inhumanlty perpetrated within Its boundaries. Max Frisch's Andorre and Rolf Hochhuth's The Representative embody, each in its own way the 2Oth century's sense of shame and horror at those events with which the century has yet to come to terms. They are both extreme reactions agalnst the image of the Jew whlch the Nazi propogandized in the 1930s.

- Description: The tolerances to sea water, sodium chloride and sodium sulphate of various cichlid, cyprinid and anabantid species which occur naturally in or near the Eastern Province region of Southern Africa, were determined, and correlated with their distribution ranges. Of the nine freshwater species tested, only Tilapia mossambica is able to disperse through the sea and is therefore the only member of the secondary division (Myers 1937) present in this region. The remaining species are possibly all limited to the use of freshwater links for dispersal between river systems. Death of fish in sea water and in sodium chloride is chiefly due to loss of osmotic control, but in solutions of sodium sulphate a pronounced toxic effect is responsible for death. In all the solutions used, an inverse relation between survival time and concentration is present. No evidence of any cells specialised for salt excretion was found in the gills of fish exposed to various salt concentrations.

- Description: Rocks forming part of the Main-Bird Series and the Kimberley-Elsburg Series of the Upper Division of the Witwatersrand System are found in the mine. The sequence studied starts with the Middle or MB 6 Zone of the Livingstone Stage followed by the Upper or MB 5 Zone. The Vaal Roof, forming the base of the Vaal Stage, rests disconformably on the older rocks. The Stage is subdivided into the Vaal Reef Zone, the Lower Vaal Zone, the Argillaceous Zone and the Upper Vaal Zone. The lower and upper contacts of the Argillaceous Zone are gradational. The Kimberley Stage follows unconformably and comprises the basal Gold Estates Conglomerate Zone, the Denny's Zone and the Gold Estates Zone. The overlying Elsburg Stage may be subdivided into the Bastard Zone and the Upper Elsburg Zone on lithological grounds. Most of the rocks are indurated quartz wackes with only a few orthoquartzite horizons such as the Denny's Zone and the immediate hangingwall of the Vaal Reef. Microscopically the rocks consist of detrital quartz and chert grains in a fine-grained sericitic to partly siliceous matrix which may constitute more than 50 per cent of the rock. Heavy minerals, such as zircon, chromite, rutile, leucoxone, pyrite, tourmaline, epidete, apetite and magnetite, occur in most of the zones. The Vaal Reef, the economic horizon, is of small-pebble, oligomictic conglomerate, often containing thucholite seams and granules, and varying in thickness from a mere parting to more than five feet. There appears to be a correlation between greater pebble size and higher ore grade but no correlation of sorting coefficients and gold value. The mineralogy of the Vaal Reef was studied by means of polished sections and heavy mineral concentrates. The minerals identified include gold, pyrite of several ages, pyrrhotite, chalcopyrite, uraninite, galena, brannerite, gersdorffite or cobaltite, skutterudite, linnacite, danaite, niccolite, pentlandite, magnotite, zircon, chromite, rutile, leucoxine, monazite, sphalerite, tourmaline, and fluorite. From a study of the silver content of gold in the Vaal Roof it is concluded that the variations in apparent fineness are a reflection of the composition of the gold in the original source rocks. There is a definite uranium-gold relationship in the Vaal Roof. With increase in grade the amount of U₃O₈ increases but the U₃O₈:AU ratio decreases. Use of these reations may indciate the payability in cases of incomplete core recovery.The intrusive rocks were studies in detail. Six types of intrusive rocks were found. From oldest to youngest those are quartz diabase (of three varieties), amygdaloidal diabase, ilmenite mela-microdiorite, mottled microdiorite, olivine lamprophyre and ankeritic beforsite, ranging in age from Lower Ventersdorp to post-Karroo. Most of the intrusives are highly altered due to the effects of regional metamorphism and deuteric alteration. Later formations, such as the Langgeleven and Allanridge Formations of the Ventersdorp System and the Black Roof and Dolomite Series of the Transvaal System, occur on the property. The various formations have been subjected to faulting and folding.

- Description: Rocks forming part of the Main-Bird Series and the Kimberley-Elsburg Series of the Upper Division of the Witwatersrand System are found in the mine. The sequence studied starts with the Middle or MB 6 Zone of the Livingstone Stage followed by the Upper or MB 5 Zone. The Vaal Roof, forming the base of the Vaal Stage, rests disconformably on the older rocks. The Stage is subdivided into the Vaal Reef Zone, the Lower Vaal Zone, the Argillaceous Zone and the Upper Vaal Zone. The lower and upper contacts of the Argillaceous Zone are gradational. The Kimberley Stage follows unconformably and comprises the basal Gold Estates Conglomerate Zone, the Denny's Zone and the Gold Estates Zone. The overlying Elsburg Stage may be subdivided into the Bastard Zone and the Upper Elsburg Zone on lithological grounds. Most of the rocks are indurated quartz wackes with only a few orthoquartzite horizons such as the Denny's Zone and the immediate hangingwall of the Vaal Reef. Microscopically the rocks consist of detrital quartz and chert grains in a fine-grained sericitic to partly siliceous matrix which may constitute more than 50 per cent of the rock. Heavy minerals, such as zircon, chromite, rutile, leucoxone, pyrite, tourmaline, epidete, apetite and magnetite, occur in most of the zones. The Vaal Reef, the economic horizon, is of small-pebble, oligomictic conglomerate, often containing thucholite seams and granules, and varying in thickness from a mere parting to more than five feet. There appears to be a correlation between greater pebble size and higher ore grade but no correlation of sorting coefficients and gold value. The mineralogy of the Vaal Reef was studied by means of polished sections and heavy mineral concentrates. The minerals identified include gold, pyrite of several ages, pyrrhotite, chalcopyrite, uraninite, galena, brannerite, gersdorffite or cobaltite, skutterudite, linnacite, danaite, niccolite, pentlandite, magnotite, zircon, chromite, rutile, leucoxine, monazite, sphalerite, tourmaline, and fluorite. From a study of the silver content of gold in the Vaal Roof it is concluded that the variations in apparent fineness are a reflection of the composition of the gold in the original source rocks. There is a definite uranium-gold relationship in the Vaal Roof. With increase in grade the amount of U₃O₈ increases but the U₃O₈:AU ratio decreases. Use of these reations may indciate the payability in cases of incomplete core recovery.The intrusive rocks were studies in detail. Six types of intrusive rocks were found. From oldest to youngest those are quartz diabase (of three varieties), amygdaloidal diabase, ilmenite mela-microdiorite, mottled microdiorite, olivine lamprophyre and ankeritic beforsite, ranging in age from Lower Ventersdorp to post-Karroo. Most of the intrusives are highly altered due to the effects of regional metamorphism and deuteric alteration. Later formations, such as the Langgeleven and Allanridge Formations of the Ventersdorp System and the Black Roof and Dolomite Series of the Transvaal System, occur on the property. The various formations have been subjected to faulting and folding.

- Description: Marrubiin and the other two diterpenoids, compounds X and Y, which had previously been isolated from Leonotus leonurus have been reinvestigated. Although the structure for marrubiin is well known its stereochemistry has been the subject of protracted discussion and is by no means secure except at C₅ and C₁₀ . N.M.R. spectral evidence showed that the lactone ring was cis-fused and β-orientated. Dehydration experiments carried out by previous workers were repeated, in order to resolve the residual uncertainty regarding the stereochemistry at C₉, an attempt was made to prepare iodoacetyl marrubic acid for X-ray crystallographic studies. Compound Y, C₂₀H₂₈0₃, a triply-unsaturated compound was shown by spectral studies to contain a furan ring and an α,β- unsaturated keto-group. It possesses a hydroxyl group incapable of acetylation, but readily removed by alkali and dehydrating agents to yield a tetraunsaturated compound, anhydro~Y; the hydroxyl is thus tertiary, Isolation of 1:2:5-trimethylnaphthalene on dehydrogenation indicated a relationship with the labdane diterpene group and supported the C₂₀ formula, The position of the α,β-unsaturated keto-group was resolved by interpretation of the ultraviolet spectra of degradation products and also by isolation of 1:2:3:5- trimethylnaphthalene on dehydrogenation of a suitable grignard product, The presence of a β-substituted furan was further indicated by colour reactions and confirmed by mass and n.m.r. spectra. The skeleton of compound Y is correlated with marrubiin via "iso-ambreinolide " and its stereochemistry is discussed. Further stereochemical assignments are postulated from the study of the n.m.r. spectra. Compound X, C₂₀H₂₈0₅, was shown by spectral and chemical evidence to be a diterpenoid dilactone containing an ether bridge between C₉ and C₁₃ Isolation of 1:2:5 trimethylnaphthal ene on dehydrogenation showed it to be closely related to marrubiin, This was supported by n.m.r. spectral results. A structure for compound X is proposed and the stereochemistry discussed. The aerial portions of Leonotis leonitis were also extracted and shown to contain a new compound, compound R. Preliminary investigation showed that it was a dilactone containing a furan ring, The n.m.r. spectrum of the compound is discussed.

- Description: J,F.w. Kühn, a member of the Moravian Mission Board, wrote in 1871 to the Superintendent at Genadendal that the closed settlements in South Africa were a precious and unique feature of mission work for which the brethren should be grateful. While he had been at the Gape, he had suffered under the difficulties of their management, but from the distance, and in comparison with mission work elsewhere, he had learnt to appreciate them as a great blessing. The questions arise: How dld they originate, develop and survive for so long? What were their characteristics, advantages and limitations? What factors contributed to their development? How did they fit into their milieu and influence it? The following thesis is an effort to give a detailed history of their development and an appraisal. I have endeavoured to give a vivid picture of personalities and events within the limits of historical correctness, because I consider it the noblest aim of historical research to confront us with the past in such a way that personal understanding becomes possible. In as much as we meet those who have made history. or have been part of it, in person, we can arrive at a deeper appreciation of their achievements, problems and failures.

The imagery of night: the significance of night in artistic images and philosophies

- Description: Introduction: At first glance, darkness is merely the absence of light, and is therefore negative; hence the traditional equation of night with death, evil and the creatures of the underworld. But a closer study will reveal that darkness is also a positive force; examples can be cited from various cultures where darkness was thought to have given birth to light. The subterranean is the realm of fertility; the worshippers of Dionysius realised this, as did the followers of the world-wide cult of the Great Earth Mother. The realm of darkness is also the habitat of the mystic. In this essay, we will attempt to define the nature of nocturnal imagery, and to trace the various ways in which mankind has sought to reconcile himself with the powers of darkness.

- Description: The chemical reactivity of a solid is influenced to a marked degree by the presence of imperfections or defects in the solid. Bond strengths are considerably weaker at points of imperfection than elsewhere in the solid, and hence the initiation of reaction is favoured at these sites due to the relative ease of bond rupture. Line defects, such as edge or screw dislocations, jogs, Smekul cracks etc, are of prime importance in such changes. The surface of a solid or in intergranular boundaries, where a state of strain exists, are also favourable places for the initiation of a reaction, Point defects e.g. vacancies or interstitialions or atoms also play important roles in chemical change, often in conjuction with line defects.

The morality play as prelude to Elizabethan drama

- Description: Although it is generally accepted that the Morality Plays greatly influenced Elizabethan drama, this statement is often followed by the rider that they are dull and lifeless and that their chief legacy is a sense of moral earnestness which also characterises the best Elizabethan drama. The aim of this thesis has been to read the Morality Plays closely and in an appreciative spirit in order to find out what significant contribution they do make to the techniques of Elizabethan drama and to a proper understanding of it. Chapter I discusses the earliest complete Morality, The Castle of Perseverance, which is the longest and most comprehensive of all the Moralities. The chapter tries to show what a Morality is about and how it differs from the great mediaeval cyclus, the Mystery Plays. It is also an attempt to relate the early Morality Play to other mediaeval literature and to show that it is closely linked to the homeletic literature of the period. Chapter II is a study of three Moralities of the period 1500- 1520. There are fewer Moralities in this period and the plays chosen show a marked similarity to The Castle of Perserverance in their structure, although they differ from the earlier Moralities in their attitude to their subject matter and in their portrayal of the different allegorical characters. The plays under discussion are Nature, Mundus et Infans and Magnyfycence Chapter III; the period after 1535 was a period of great political and religious upheaval and this chapter discusses the plays written for propaganda purposes in the strife between Catholic and Protestant. John Bale's Three Laws, an anti-Catholic play, was chosen because Bale is a startlingly original dramatist who makes use of techniques derived from the liturgy and from emblematic devices, and because he tries to mould the Mystery Plays and the History Plays into a Morality framework. The other plays The Conflict of Conscience was chosen because of its affinity to Dr Faustus and also because it tries to show the psychomachia in psychological, personal terms rather than in a general allegorical manner. Chapter IV discusses three later Moralities, Cambyses, Horestes and Appius Virginia, which portray historical or fictional characters in situations of conflict. They were chosen because they seem to show that the Morality Plays laid the bases for the Elizabethan tragic situation and the Elizabethan tragic hero. With such diverse material, it is difficult to trace a clear line of development from one play to the next, but each group of plays has its own contribution to make to our understanding of Elizabethan drama.
