- Description: The study of administrative processes is a relaltively new one both in the field of history and sociology. In both disciplines what is required is study of the sructure and growth of adminstrative systems and of the impact of administrative action on the community it seeks to serve and which it often provokes. In the field of history, Professor F. Tout in his chapters on administrative history ... gave new vitality and understanding to medieval studies. In the main, South African history, though probably not more so than other Commonwealth countries, has been less fortunate. Preface, p. 1.

- Description: INTRODUCTION. The fact of the Risen Christ is the focal point which gives meaning to the Christian faith as a whole. Modern thought, while not denying the Resurrection, tends to confine it to its doctrinal or credal significance. In contrast, the early Christians were conscious of the presence of the Risen Lord and consequently the Resurrection was a fact of living experience. As mere history it loses its moral significance; as mere faith it becomes vague belief in deathlessness, and undermines the reality of the Atonement. The Resurrection is both fact and faith.

- Description: As the title indicates, this is a study of the historical emergence of geography as a subject in Cape schools, and covers the period 1772-1951. The account is not merely descriptive and factual, for wherever possible an attempt is made to assess the nature and scope of the geography which was taught at different periods in relation to modern, authoritative ideas concerning the pedagogic application of the subject in the school. The work as a whole is predominantly concerned with the historical development of geography in the secondary school. However, in the initial four chapters the slight and insubstantial nature of the available data precludes the possibility of differentiating between geoeraphy of primary standard and that of secondary standard, and in these early chapters all references to the subject are consequently generalized. In Chapter 5, which deals with the period during which Langham Dale was Superintendent-Genera l of Education, geography of secondary standard becomes distinguishable from that of primary standard for the first time, and from this point onwards the two are differentiated to the fullest extent possible, and the former is chiefly emphasized. The entire study is presented against a broad background of relevant, educational developments of a general nature.

- Description: [From Introduction]. In 1955, Dry and Gledhill, both formerly of this Department, published their paper on the Solubility of Mercurous Chloride in Water at 25°0, and it was originally intended that this thesis should be an extension of the study to cover the temperature range from 5 t o 55°0. A preliminary investigation at 25°0, however, failed to yield results which were consistent with their findings, even though their apparatus and experimental technique were used. In an effort to resolve these difficulties their method of saturating the calomel in the conductance cell was thoroughly investigated, and as this procedure was found to be responsible, it was necessary to evolve an entirely new approach. The technique finally adopted was to saturate the mercurous chloride solutions by mechanical stirring in siliconed vessels and to carry out the conductance, pH, and total mercury concentration measurements on the filter ed solution. This method gave good results, and was free from the many extrapolations prevalent in the original procedure.

- Description: The main object of the present investigation has been to establish a titration curve for mohair keratin and to compare it with similar data for wool, to determine whether the differences in physical and chemical properties could be attributed in any way to the acidic and basic character of these fibres. As shown in subsequent discussion such measurements provide extremely useful information regarding the chemical structure of proteins in general, and in the technical fields involving processes such as wool scouring, carbonizing and dyeing. The study has been extended to include certain modified wools, i.e. photochemically damaged, and oxidized keratin. The most successful contribution to the titration data of wool keratin is the work of Steinhardt and Harris and subsequent authors have tended to adopt their procedures without modification. In the present study attempts have been made to obtain a clearer understanding of the fundamental processes. New techniques and analytical methods have been introduced to improve the accuracy of the measurements.

- Description: The thermal decomposition of silver permanganate, pre-irradiated in BEPO and in a ⁶°C₀ Ϫ 'hot spot' has been investigated in the temperature range 100 - 125°C. The results are similar to those for irradiated KMn0₄ and the mechanism proposed for the latter is again suggested. The activation energy for the migration of point defects over the induction period is 1.03 ev. The decompositions of unirradiated and irradiated crystals differ in that the latter undergo physical disintegration over the acceleratory period. X-ray studies immediately prior to disintegration show strain and fragmentation in the irradiated crystal. An explanation involving the annealing of point defects at dislocation is advanced to explain the changes produced in the p/t plots with increased dosage, and fixed decomposition temperature. Summary, p. 94.

- Description: Transport undoubtedly occupies a most important place in the economic and commercial life of all countries. In this respect South Africa is no exception, and very briefly, the principal economic functions of transport are enumerated below. 1. Transport establishes communication between consumers and the producers of goods or services. 2. Transport facilitates the movement of persons between the place where they live and the place where they work - usually this is a daily procedure, but in South Africa it also entails the movement of large numbers of Natives from the Native Reserves to work for some months at a time either in the gold mines or in the several urban areas of the Union. 3. Transport makes geographical specialization possible, for agricultural or mineral resources will only be exploited, or specialized industries established, in a particular area, if the commodities produced can be transported to other parts of a country, or the world; and other capital and consumer goods brought to the producers living in the area of specialized production. 4. Transport faciitates industrial production because, of raw materials which come from many sources. Furthermore, transport enables the finished products of industry to be distributed to the markets in which they are sold. In all these cases, the efficiency of transport has to be measured not only in terms of its cost, but also in terms of its efficiency, which includes, inter alia, the time taken, the frequency of services, the safety of goods and passengers while in transit and the provision of various special services, such as the provision by railway undertakings of private siding facilities. This thesis will be divided into five parts, the first dealing with the technical and commercial development of the Buffalo Harbour. It has been decided to deal with the Harbour first because, not only has it been the focal point of the transport system of the Border Region since the latter part of the nineteenth century, but it has dominated the economic and commercial development of East London, as well as that of the Border Region as a whole. The second part deals with the evolution of the railway system from the 166 mile long East London and Queenstown Railway, to the present 1,110 miles of the Cape Eastern System. This historical chapter is followed by an analysis of the traffic of the Cape Eastern System. Part Three deals with the theory, practice, and economic consequences, of railway rating policy. Part Four is a detailed analysis of the goods traffic forwarded from, and received at East London in the period from 1st April, 1953 to 31st March, 1956. Part Five deals with roads and road transport. Finally, certain conclusions are offered, based on the significant points revealed by the investigation on which this thesis is based. In this thesis the theory of transport will not be dealt with in detail for it is essentially a factual account of the development of the transport system of the Border Region and an analysis of the present situation. It has unfortunately not been possible to make in this thesis a study of railway finance or railway economics with regard to the Cape Eastern System, for the data upon which to base such an investigation are not available for the Cape Eastern System in isolation. No attempt will be made to assess either the technical or the operating efficiency of the railway system for not only would this require more data than are available, but also a technical knowledge not possessed by the writer.

A brief description of some aspects of solar physics relevant to the study of solar noise is given, and the literature relating to the correlation of radio effects with solar disturbances is reviewed. Chapter II. A concise description of the apparatus constructed for the continuous recording of the flux density of solar radio noise at a frequency of 300 Mc/s is given, with some mention of difficulties experienced, and how these were overcome. Full circuit diagrams of electronic apparatus, and illustrative photographs, are supplied. Chapter III. The development of theories of the origin and propagation of solar noise radiation is historically reviewed and the success of each theory in explaining or predicting observed phenomena, is assessed. A working model is chosen from among these theories, and reasons for its adoption are given. Chapter IV. Observations made by the author of solar radiation at a frequency of 300 Mc/s are described, together with a description of the objects and methods, of analysis of the records. Chapter V. Phenomena observed by the author are compared with those observed by other workers. It is concluded that storm bursts are caused by transients similar to those producing Type II and Type ITI bursts, and a model for the production of storm bursts is tentatively suggested. Chapter VI. Suggestions for further research, including suggestions for methods of testing the author's conclusions, are made.

- Description: The work described in this dissertation was undertaken in an attempt to obtain a better understanding of the causes and relationships of insecticide resistance in Blue Tick, Boophilus decoloratus Koch, which has become an acute problem in some localities of the country. The work was undertaken at the Research Department of African Explosives and Chemical Industries Limited over a period of six years from 1953 to 1958. An attempt has been made to keep up to date with the published literature on the various aspects of these investigations up until the end of 1958. Information gained from the literature subsequent to end of 1958 has been made use of but it has not been possible for a number of reasons to follow all recent developments in the various aspects of insecticide resistance published during 1959. In the execution of this work assistance has been obtained from colleagues better equipped in the field of organic chemistry, biochemistry and statistics, than the author. Where information so gained has been used it has been duly acknowledged. Considerable assistance was rendered by laboratory assistants who were responsible for performing the considerable amount of routine collection, breeding and testing of the biological material. The blue tick is not a convenient experimental organism for studies on insecticide resistance. Even with the best facilities the tick cannot be bred satisfactorily and in consequence all supplies had to be collected from naturally-occurring populations. Although this had decided advantages in some aspects of the work, a great deal of useful information might have been obtained if certain strains of ticks could have been maintained. The lack of a standard sensitive reference strain has been a considerable disadvantage which could not be overcome and which has influenced the manner in which this work has been carried out. Because the tick could not be bred artificially the work could only be undertaken with unfed larvae and fully engorged adult females . Larvae are extremely small and in consequence could only be handled in batches while the fully engorged female is sluggish and contains a large quantity of semi-digested mammalian blood which invariably interfered with chemical or biochemical studies.

- Description: The work described in this dissertation was undertaken in an attempt to obtain a better understanding of the causes and relationships of insecticide resistance in Blue Tick, Boophilus decoloratus Koch, which has become an acute problem in some localities of the country. The work was undertaken at the Research Department of African Explosives and Chemical Industries Limited over a period of six years from 1953 to 1958. An attempt has been made to keep up to date with the published literature on the various aspects of these investigations up until the end of 1958. Information gained from the literature subsequent to end of 1958 has been made use of but it has not been possible for a number of reasons to follow all recent developments in the various aspects of insecticide resistance published during 1959. In the execution of this work assistance has been obtained from colleagues better equipped in the field of organic chemistry, biochemistry and statistics, than the author. Where information so gained has been used it has been duly acknowledged. Considerable assistance was rendered by laboratory assistants who were responsible for performing the considerable amount of routine collection, breeding and testing of the biological material. The blue tick is not a convenient experimental organism for studies on insecticide resistance. Even with the best facilities the tick cannot be bred satisfactorily and in consequence all supplies had to be collected from naturally-occurring populations. Although this had decided advantages in some aspects of the work, a great deal of useful information might have been obtained if certain strains of ticks could have been maintained. The lack of a standard sensitive reference strain has been a considerable disadvantage which could not be overcome and which has influenced the manner in which this work has been carried out. Because the tick could not be bred artificially the work could only be undertaken with unfed larvae and fully engorged adult females . Larvae are extremely small and in consequence could only be handled in batches while the fully engorged female is sluggish and contains a large quantity of semi-digested mammalian blood which invariably interfered with chemical or biochemical studies.

- Description: [Summary] Some properties of zirconium compounds in aqueous solution have been determined using physico-chemical techniques. Zirconium oxychloride was used as the source of zirconium in all detailed investigations; zirconium sulphate was used in a few cases for comparative purposes. The Stokes diaphragm cell method has been used to determine the diffusion coefficient of zirconium in hydrochloric acid solution. It was found that the diffusion coefficient fell progressively with time, a limiting value being reached 4 to 5 weeks after dissolving the salt, and it was demonstrated that particles in the aged solutions were more homogeneous than in freshly prepared solutions. The limiting values were concentration dependent; dilute solutions had a lower diffusion coefficient than the more concentrated solutions when measured at the natural pH. In the presence of added acid the rate of diffusion was increased until a limiting value was reached in 0.5 M acid. The addition of alkali or complexing acids reduced the rate of diffusion.

The cost of discipleship and the reward of righteousness

- Description: CHAPTER ONE. In the Old Testament we meet with the problem of suffering and reward, and the attempts made to resolve it. It becomes the one great problem after the time of the Exile. Most commentators are agreed that it grew to hold that place in relation to the increase of importance of the individual in Hebrew thinking. While certain aspects of the problem are presented in Jeremiah, Ezekiel, Isaiah, and Psalm 73, the most important contributions are made by the Deuteronomist and the poet who wrote the Book of Job. The Deuteronomist theory presents the belief that there is a rigid correspondence between the sins of the individual and his suffering. The reply in Job makes it clear that this is not so. Job himself passes through the desperate situation of feeling deserted by God to a certain faith that whatever happens to him, God is faithful. CHAPTER TWO. Jesus' teaching on "discipleship". Basically Jesus's teaching centres around Mark 8 : 34, "Whosoever will come after me, let him deny himself and take up his cross, and follow me". The cost of discipleship from this point of view means, then, that even as Jesus Himself bears the cross for the salvation of the world, so the disciple is called upon to bear that cross in association with his Lord. Jesus offers the reward of both a present foretaste and a future consummation of eternal life, as the disciple shares in His resurrection. St. Paul's teaching of "Life in Christ". The central teaching of Paul is found in Romans 6 : 11, "Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord." The cost of discipleship is death, the death of self- will. It means being crucified with Christ. The reward of the righteous man is both a present and future participation in the risen life of Christ. CHAPTER THREE The need of man. Because man is a sinner, being estranged from God in whose image he was created, he stands in need of being reconciled to God. This he cannot do himself because, to his sin, he is not able to make the full sacrifice of his self-will. "Man requires to be put right with God because as a matter of fact he is not right." The Christ. Only in the person of the God-man is God able to effect man's resolution. Jesus, the Christ, who alone of all men did not participate in the sinfulness of man, is this God-man, realising in Himself the fact that salvation can only be wrought by one who is both God and man. The necessity of the Cross. The death of the Christ is seen to be necessary both from the side of man and from that of God. It was essential that the Christ should give His life for man; everything for His purpose of salvation turns on the will to die. He must give himself to reconcile man to God. The sacrifice of the Cross. Seen in the context of the Old Testament sacrificial system, what is important about the sacrifice of the Christ is that on the cross He offered up His life for man. The sacrifice of the Christ is both in the category of divine revelation and that of human response. It is the love of God in its utter self-offering making a way whereby the sinner might be reconciled to Him. The use of the Ransom Theory of the atonement is regarded as inadequate for expressing this cost. Basically it is a costly sacrifice because it is the self-offering of the Son of God upon the cross. CHAPTER FOUR The New Testament picture. A closer analysis is made of the New Testament teaching of discipleship, where it is seen that it is required of men that he should make, like the Christ, the costly sacrifice of himself. Soren Kierkegaard. This existential thinker felt the need of awakening men to a full recognition of the costliness of life. Despair. Man, due to his state of sinfulness is in despair, for "sin can be defined as despair at not willing to be oneself or not willing to be oneself before God." It is necessary to make the leap of faith to pass from this despair. The Three Stages. These are the aesthetical, ethical and religious stages. The individual must enter the last by making the leap of faith out of his despair; and this leap means the costly commitment of the self to the Christ. "Purify your hearts." In this book, Kierkegaard analyses man's double-mindedness. He comes to two conclusions. "If anybody would will the Good truly, then he must with knowledge of himself be ready to renounce all double-mindedness. If anybody would will the Good truly, then he must be ready to do all for the Good, and suffer for for the Good." His teaching on the cost of discipleship could be summed up thus : "The negating of one's finite self, or the negating of one's finitude means for him nothing less than the conscious sacrifice of all that is finite." Paul Tillich. Tillich deals with the ultimate problem of being and non-being, and in the "Courage to be" he develops the reactions of the individual when he is faced with the possibility of his non-being. The individual can either lose himself in his world by the courage to be as a part, or lose his world in himself by the courage to be as himself. These two forms of courage are transcended by the courage to accept acceptance, which is the ultimate courage to be, in which the individual accepts the fact that though he is sinful, yet God accepts him. This courage is the outcome of faith, which is found in an encounter with the New Being, in which the self is lost in the Christ, being found also in the Christ. The disciple surrenders himself that he may be made more truly himself. CHAPTER FIVE In this chapter an attempt is made to analyse the reward of righteousness. This reward is firstly seen to be the outcome of the life of discipleship and not its motive. Basically it is found in the new quality of life which is called eternal life. It is a reward both in the future and in the present. In the future it is the fullness of life in communion, peace and joy in the presence of God. In the present it is a foretaste of that life which is to come, a present possession in the midst of finitude of communion, peace and joy with God. Ultimately this means participation in the resurrection of the Christ. CHAPTER SIX We can conclude from this thesis, then, that Jesus the Christ is the prototype of the Christian. Discipleship is costly because it means participation in His utter self-offering of Himself; and the righteous man, who is the one who by faith commits himself to and in the Christ, is rewarded with the new quality of eternal life. The death and resurrection of Jesus the Christ are the criteria of the cost of discipleship and the reward of the righteous man.

- Description: The concept of a distinctively South African poetry in English has been, and still is, derided as a "pipe dream" as part of the fallacy which stems from the desire for a "national" literature. In 1955, for instance, C.J. Harvey (in an article containing much common sense as well as sound literary judgment) denounced the self-conscious hunting for "Local Colour" which engrosses so many South African writers. Harvey claimed: "Our civilization is not "South African", except in trivial details, it is Western European, and more specifically as far as poetry written in English is concerned, English ... ". There is a serious error of emphasis here. It would be more accurate to say that our ancestors brought Western European civilization to this continent. To imagine that this civilisation has not undergone and is not still constantly suffering a subtle but far-reaching metamorphosis in Africa would be to fly in the face of reality. White South Africans do not only carry the same identity-card but they can be distinguished from Frenchmen, Englishmen or Irishmen by more than "trivial details". This thesis is an examination of some af the earliest English written in southern Africa, particularly of the verse produced by our poetasters and near-poets. It attempts, during the course of this examination, to call attention to a few of the more significant changes which have arisen as the result of the importation of Western civilsation to an African frontier. Further I hope to show some at the varying ways in which these differences affected the white pioneer and how this has been reflected in our verse since pioneering times. In this sense the Frontier may be thought of as the background against which South African English writers developed certain characteristic traits. Intro., p. 1-2.

- Description: [From Introduction]. The thermal decomposition of solids is characterized by the formation and growth of nuclei at sites on the surface of the solid or within the crystal lattice. Such nuclear formation is favoured by disorganisation of the crystal either by mechanical damage, or by the presence of impurities. Disorganisation results in positions which have a high thermodynamic instability. The nuclei are likely to be formed initially at the corners and the edges of the crystal since these are more prone to damage. Careful handling and storage in vacuo often leads to a large reduction in their number, while deliberate scratching of the surface facilitates their production. The number of potential sites for nuclear formation is also increased by pre-irradiation with ultra-violet light, though there are indications that a different type of nucleus may be produced. Nucleation can be facilitated by pre-irradiation with electrons, neutrons, X-rays, gamma-rays and atomic particles. The nature of the nuclei is not always clearly defined, but it is generally accepted that they are composed of solid reaction products e.g. in the decomposition of barium azide and silver oxalate, nuclei of metallic barium and silver, respectively, are formed.

- Description: From Preface: In this Ecumenical Age it is necessary that each Christian Communion consider again its particular doctrine of the Church, and restate it for the benefit of the whole Body of Christ. This Thesis is an attempt to show some historical and theological facets of the traditional Congregational doctrine of the Church. However, it must be stated that a full exposition of Congregational ecclesiology is an impossible task for any thesis. Firstly, inherent within Congregationalism is the fear of dogmatizing about matters of faith and practice. It has expressed itself in Statements and Declarations but always with the qualification that these things are 'commonly believed amongst us' Therefore, Congregationalism, while it has a characteristic ecclesiology, has never formulated a rigid pattern of Churchmanship which has to be adhered to by all the Churches. Secondly, a full study of Congregational ecclesiology would entail the study of the practices of every Congregational Church through the ages. That is an impossible task. Therefore, we have been confined to available material; but material which nevertheless expresses what we would regard as traditional congregationalism. Thirdly, a study of this nature must be content merely to state, however critically, what Congregationalists have believed about the Church at various times in the history of Congregationalism. It is impossible to convey the pulse and feeling of the life of a Congregational Church, for it is very important in seeking to understand any Churchmanship, not only to understand its theological form and structure, but also to experience its ' koinonia ' in its common life and worship.

It has expressed itself in Statements and Declarations but always with the qualification that these things are 'commonly believed amongst us' Therefore, Congregationalism, while it has a characteristic ecclesiology, has never formulated a rigid pattern of Churchmanship which has to be adhered to by all the Churches. Secondly, a full study of Congregational ecclesiology would entail the study of the practices of every Congregational Church through the ages. That is an impossible task. Therefore, we have been confined to available material; but material which nevertheless expresses what we would regard as traditional congregationalism. Thirdly, a study of this nature must be content merely to state, however critically, what Congregationalists have believed about the Church at various times in the history of Congregationalism. It is impossible to convey the pulse and feeling of the life of a Congregational Church, for it is very important in seeking to understand any Churchmanship, not only to understand its theological form and structure, but also to experience its ' koinonia ' in its common life and worship.
