- Description: The cicada genus Tugelana Distant 1912 and its only species are redescribed. The genus is best characterized by the shape of the male urite. T. butleri Distant 1912 is found on the coastal plateau of southern Mocambique and the adjoining tropical part of South Africa. Tugelana is most closely related to the genera Azanicada Villet 1989, Systophlochius Villet 1989 and Platypleura Amyot and Serville 1843, which form a clade within the tribe Platypleurini Schmidt 1918.

- Description: The case study has its source in the author's attempt to translate his novelette Alitshoni lingaphumi (Waiting for sunrise) into English. Current developments in the sociopolitical arena make it increasingly important for linguists to focus on the interchange between the indigenous languages and the two dominant languages, English and Afrikaans. This would break down the artificial baniers so enthusiastically maintained in the past. Secondly, such an exercise would also help to overcome prejudicial ignorance. Some of the issues highlighted include culturastructural, lexicsyntactic, and semantic differences between Xhosa and English, as exemplified in the text in question.

- Description: The monotypic genus Bavea Distant 1905 and its constituent species are redescribed. The forewing venation, tymbal structure and aedeagal structure are diagnostic. Bavea concolor (Walker 1850) is endemic to the eastern Cape province of South Africa. The closest affinities of the genus appear to lie with the genera Xosopsaltria Kirkaldy 1904 and Tettigomyia Amyot and Serville 1843, and less closely with Stagira Ståi 1861.

- Description: Release of betamethasone valerate (betamethasone 17-valerate) from 3 extemporaneous cream formulations (1 control, 1 containing propylene glycol, and 1 containing \b/-cyclodextrin) and a commercial cream formulation (Betnovate) was compared using the human skin blanching assay in 12 healthy male volunteers. All 3 extemporaneous formulations showed similar drug release rates, equivalent to or better than the commercial preparation containing betamethasone in a 10 fold higher concentration. Electron microscopic examination showed considerably finer dispersion of the oil phase in the extemporaneous formulations. It was concluded that the increased surface area available for partitioning of betamethasone between the cream and the skin is responsible for the improved topical availability of the drug from the extemporaneous formulations.

- Description: Brown trout were introduced to the Van den Boogaard River on subantarctic Marion Island in 1964, and a small population became established. The last individual was seen in 1984, and the species is now considered to be extinct on the island. Their diet was exclusively allochthonous, with snails and spiders predominating. Ages estimated at six to eleven years showed that spawning must have occurred since the original introduction. Since the Van den Boogaard River enters the sea via a waterfall, it is postulated that trout were not able to practice an anadromous life-style, and that this, as well as other factors connected with the impoverished nature of the stream, led to dwarfing of the resident population. No further introductions of alien fish to Marion Island should be contemplated.

- Description: Dated distribution records of the Wattled Starling Creatophora cinerea have been assembled from the literature, museum specimens, atlas records, and other unpublished observations. The bulk of these records are from the period 1980–89. Breeding records are sparse, but breeding appears to be seasonal in the winter rainfall area. In summer rainfall areas nesting occurs from spring through to autumn, dependent on the presence of abundant insects. In most areas winter records (June to August) predominate, but in the eastern lowveld areas of South Africa Wattled Starlings are recorded most often in spring and summer. The species is correctly described as nomadic, and the pattern of occurrence does not suggest regular migration.

- Description: Juvenile African Pied Starlings (Spreo bicolor) have a dark brown iris, but after the first year iris color changes progressively until adult birds have a creamy-white iris. Using light and electron microscopy, we found that the pigment epithelium of the iris remains pigmented, while changes occur in the pigmentation of the anterior border layer and the stroma of the subadult and adult iris. In the juvenile iris the anterior border layer is darkly pigmented, but in the subadult iris this pigmentation is lost progressively, while pigment granules are deposited in the stroma. In adults, the stroma is heavily pigmented with a solid refractory pigment, and the anterior border layer is clear.

REE, Y, and to a lesser extent Cr, are mobile and redistributed within the profile without a net loss of these elements from the profile. Large positive Ce anomalies are developed in oxidized weathered products by preferential leaching of the other REE's. Negative Ce anomalies and REE enrichment is a feature of less altered dolerite.

This political maturity of the comrades went as far as to give a proper critical analysis of the structures of our organisation. The analysis accepted that the functioning of some of our organisation’s structures is not up to standard. The congress also noted that the participation of the general membership in the activities of the organisation is not satisfactory. As it is typical of matured comrades, the congress realised that such problems are not peculiar to Potwa. Shortcomings such as these are indicative of a huge and growing organisation. Because of this, the comrades explored ways and means of solving these problems. The congress concluded that the opening of a regional office combined with effective usage of our Potwa newsletter would go a long way in solving some of our problems.

- Description: A lack of agricultural marketing facilities is generally seen as one of the major obstacles to agricultural development. However, subsistence producers in southern Africa are influenced by certain exogeneous factors, such as competition from commercial production, the well-developed marketing system, and off-farm employment opportunities in South Africa. This paper studies the effect of the institution of an organized marketing system in Ciskei on the level of agricultural production. This is found to have had no significant effect because the majority of the able-bodied males are working in the metropolitan areas of South Africa. This has resulted in agriculture becoming a part-time supplementary activity for women, old men, and children in the rural areas.

- Description: The possibility of an effect of zinc on the rate of tumour cell division, mediated through a regulation of cellular cAMP concentration, was investigated in the present study in rats. Dietary Zn deficiency (< 1·5 mg Zn/kg) but not Zn excess (500 mg Zn/kg) resulted in an increased cAMP concentration in transplanted hepatoma cells. Neither treatment had any effect on the cAMP concentration in regenerating liver or normal resting liver. Both the deficient and excess Zn diets resulted in a small reduction in tumour growth (not statistically significant). The results seem to indicate that the relation investigated in the present study does not apply in the cell line used.

- Description: I want to start at what may seem an unfair distance from the kind of view Colin Gardner has put forward. Early in 1947 the date is signifi-cant-a group of science students at Cambridge asked that some lec-tures on English Literature be organised for their special benefit. TR Henn responded and versions of his lectures were later published as The Apple and the Spectroscope (1951). In the book, Henn records the reaction of one of his students to Macbeth's speech at 1.7. 16-25: Be-sides, this Duncan Hath borne his faculties so meek, hath been So clear in his great office, that his virtues Will plead like angels, trumpet-tongu'd against The deep damnation of his taking off; And pity, like a naked new-born babe, Striding the blast, or heaven's cherubin, hors'd U pan the sightless couriers of the air, Shall blow the horrid deed in every eye, That tears shall drown the wind.
