- Description: Among the most difficult problems of the systematist are certain groups of tropical fishes, notably the Parrotfishes and the Lethrinidae, whose bright colours fade quickly after death. Both of these groups are especially abundant in the Indo-Pacific. The Parrotfishes are troublesome enough, but the species do tend to retain the same livery fairly constantly in life, and there are several features that provide well defined generic cleavage, as well as useful clues to species. The Lethrinidae are more difficult, having fewer variable features. Even dimensions, e.g. relative depth, are useful only when comparable stadia can be compared, as considerable general change in body shape may occur with growth. Under the water these are troublesome fishes to identify, as most species are camouflaged by an intricate pattern of cross bars, cloudy patches, and reticulations, which make them all look much alike. In addition, they are among the most wary of the reef fishes, and difficult to approach for close scrutiny. Fresh from the water, the concealing, darker, cross markings and reticulations usually fade within a few moments, and some species are not difficult to recognise, since just after death, colour and pattern are normally reasonably constant within one species, a few are almost constant, others show variation round a typical pattern. , Rhodes University Libraries (Digitisation)

- Description: Since the Kennelly- Heaviside hypothesis in 1902 of the existence of a partially conducting layer in the upper atmosphere was proved to be true by the experiments of APPLETON and BARNETT (1925) and BREIT and TUVE (1926), this region has become known as the ionosphere. The ionosphere was soon discovered to consist of, not one but several layers (Fig. 1) (i) A layer at a height of just over 100 km. called the E layer. (ii) A layer at a height of approximately 300km. called the F₂ layer. (iii) A layer at a height of approximately 200 km. called the F₁ layer; this layer differs from the other two in that it is only present during the day time in Summer. (iv) Occasional intense reflections from a height of about 100 km. are found - these cannot be attributed to the normal E layer and have received the name "Sporadic E". The presence of two E layers (E₁ and E₂) has been suggested by HALLIDAY (1936) and BEST and RATCLIFFE (l978) but until recently most workers still seem to attribute these reflections to Sporadic E. Recent measurement by rockets of the electron density at E layer heights still do not confirm whether such bifurcation exists in the E region. The diurnal and seasonal variations of the first three layers indicate that the sun is the chief agent in their production. It is generally agreed that these layers consist of ionised molecules or atoms and free electrons produced by radiation from the sun. The origin of Sporadic E ionisation is still obscure, but it is thought that these sudden increases in ionisation which occur in E layer heights are due to passing meteors. Recently it has also been suggested by SEDDON, PICKAR and JACKSON (1954) from rocket measurements that Sporadic E might be due to a steep electron density gradient above the B layer.

- Description: The aims of this investigation were firstly to find whether 371 subjects, mainly students at Rhodes University, would be able to reproduce target drawings made 470 miles away by an agent in Cape Town, by means of General Extra-Sensory Perception; secondly, to find whether any association existed between any such hit scoring ability shown and personality ratings derived from a battery of personality test material; and thirdly, to find whether providing the subjects with material designed to link them more closely with the agent would increase their scoring rate. The 17,440 drawings returned by the subjects were randomised, and scored against a randomised set of 100 drawings consisting of 50 which had actually been used as targets, intermixed with 50 that were equal in difficulty but which had not been used as targets, and which were inserted merely as controls. Three independent judges assessed the subjects' drawings, and awarded hits in terms of title, shape and association. In the crucial title hits highly significant deviations in favour of the experimental target drawings were found, the control series of drawings showing no such effects. It was found that the subjects' hits were distributed evenly throughout the whole 25 day period of the experiment for each target, and showed no tendency to occur more frequently in the week a particular drawing was being used as a target than in the other weeks when it was not. When the subjects were divided into a high scoring and low-scoring group in terms of their E.S. P. abiility, the high- scoring group proved to be significantly more extraverted (as measured by the Bernreuter B3I scale) than the low- scoring group, confirming a relationship previously reported by Humphrey. In addition the data showed several other relationships, predicted by the work of previous experimenters, although these did not reach the .01 level of statistical significance. To assess the effect of the Linkage Material the subjects were divided into an experimental and a control group. The Experimental Group was supplied with correct Linkage Material, the Control Group with incorrect Linkage Material, which they were led to believe was correct . The two sets of Linkage Material were equated in all other respects. The Experimental Group showed significant improvements in scoring rate when supplied with a photograph and description of the agent, and a probably significant improvement when supplied with squares of handkerchief which had previously belonged to him. When supplied with squares of colour, also appearing on the agent's target sheets, no significant increase in scoring rate took place on the target drawings, but a significant decrease occurred in hits scored on the control targets. By contrast no consistent significant fluctuations were shown by Control Group Subjects, leading to the conclusion that the correctness of the Linkage Material was a factor contributing to its effectiveness. A qualitative examination of the hits scored by the subjects revealed that they tended to reproduce the concepts depicted by the target drawings, rather than the actual shapes drawn by the agent, suggesting that the hits were being produced by a telepathic process rather than a clairvoyant one. The results of the experiment suggest that the subjects were assisted by the Linkage Material to gain access to the agent's mind as a whole, and not to particular items in it. This throws doubt on the correctness of Whately Carington's Association Theory of Telepathy, which the experiment was designed to test.

- Description: For some years the Institute of Social and Economic Research at Rhodes University has been engaged in an intensive study of the area of the Eastern Province of the Union of South Africa known to South Africans as the Border Region. By a singular chance an invitation from the East London Divisional Council to investigate the condition of a Border village arose when, in the course of a visit from its Secretary, sufficient data was shown concerning the conditions of village life in the region, to suggest that a special study should be made of rural problems on an intensive basis. In the first instance the enquiry directed to the Institute was administrative in the sense that difficulties were arising in the villages to warrant the establishment of sufficient authentic facts to point the way to methods of solving the immediate difficulties of the Council. While this object has not been overlooked, and it would have been less than courteous to have overlooked the demand that brought-the research into being, it has been thought necessary to widen the scope of the investigation to include materials that go beyond the administrative needs of the Council. The scope of the investigation has been widened to include an analysis of the village community as well as a co-ordinated body of brute fact. While "irreducible fact" is the basis on which the investigation rests, the attempt has been made to isolate meaning and significance of the data; it is in the latter field that deeper aspects of administrative decisions lie more often than in mountains of fact no matter how reliable. A community is an organised unit; there is no simple explanation of the way in which human social institutions work except by analysing the behaviour of people in their everyday activity. The manner in which the organisation works and be more or less efficient and there was prima facie evidence that the community of Macleantown was not organised to yield maximal efficiency. The causative factors involved in this drop in efficiency thus becomes one of the basic tasks , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: In this paper an analysis is developed of the characteristics of a group of Europeans who have been declared to be living in houses unfit for habitation in terms of the criteria laid down in the Slums Act No. 53 of 1934. It is assumed, for purposes of analysis, that the group will be transferred to municipal housing and that, like the Coloured and Africans in the City of Grahamstown, economic rent scales will be applied. This paper is, therefore, concerned with the present condition of the tenants in the slum but is predictive in terms of what will most probably happen if they are transferred to better municipally owned housing under economic rentals. The specific reasons why economic rent, without subsidisation, is likely to be applied to this group need not concern us in this paper. Even if an economic rent is not applied the discussion is held to be of value so far as sets up standards and techniques by which levels of subsidisation, if applied, might be measured. Further, the data is held to be factually interesting so far as it relates to the poverty of Europeans on which, little has been written for some years. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: Among the most esteemed by the big game angler, these fishes are of world-wide distribution, and the various species (commonly named “Yellowtail” in South Africa), are all built on much the same plan, the caudal lunate, the dorsal and anal fins long and mostly low. All are powerful swimmers, presumably able to cover vast distances, and within each genus and subgenus the different species do not differ widely from one another. As a result, there has been a general tendency for systematists to identify species, even in remote parts, with those already known. The literature reveals astonishingly few detailed original descriptions of these fishes, and there has been a regrettable tendency merely to reproduce early illustrations that are technically good, rather than to provide originals of actual specimens, which has caused widespread confusion. Two genera are treated here, viz. Seriola Cuvier, 1817 and the monotypic Seriolina Wakiya, 1924; Zonichthys Swainson, 1839 is regarded as Atlantic only, while the pelagic monotypic Naucrates Rafinesque, 1810 is so well known as scarcely to need inclusion here. , Rhodes University Libraries (Digitisation)

- 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.

The fact and meaning of the resurrection : a study in emphases

- 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: Family Eleotridae - The Gobioid fishes are one of the major trials of ichthyologists, and when general regional collections are worked up, these fishes tend to be pushed aside, and are apparently often identified with some impatience by those not especially interested. It is not indeed uncommon for later workers to find several species in a bottle supposed to contain only one, or to find one and the same fish in the same collection labelled with different names. All this is understandable, for not only are there numerous species, but almost all are small to minute, so that accurate description and especially illustration are no light undertaking. In addition, they are generally covered with mucus, so that two exactly similar living specimens, preserved in different media, e.g. alcohol and formalin, can emerge looking so completely different, that the purely museum worker may be forgiven for considering them different species. , Rhodes University Libraries (Digitisation)

The historical development of geography as a subject in the schools of the Cape Province (1772-1951)

- Identifier: vital:1974 , http://hdl.handle.net/10962/d1012702 , Geography -- Study and teaching -- South Africa -- Cape of Good Hope
- 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: Parrotfishes have long been one of the major problems of the taxonomist, largely as a result of classification based on preserved material. Workers such Bleeker, who handled fresh specimens, provided useful descriptions and at least passable illustrations of Parrotfishes. There has, in consequence, been a general tendency to use such names in preference to those of earlier workers, notably Lacepede and Valenciennes, most of whose descriptions, based on long dead specimens, not only lack accurate, or indeed any, illustration, but rarely contain critical diagnostic data. In consequence, the nomenclature has been in a state of utter chaos, and any worker privileged to travel and examine early type specimens incurs a good deal of responsibility, since the majority of other workers are usually not in a position to query his opinions about their identities. , Rhodes University Libraries (Digitisation)

- 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.
