  • A routine method for the determination of soluble ash in plant material 
    Louw, J.G.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    A routine method for the determination of soluble ash in plant material is described in detail. Evidence is presented to show that the results obtained by this rapid method compare very favourably with those obtained by ...
  • Echinococcus in dogs from Pretoria and vicinity 
    Ortlepp, R.J.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    The author describes worms of the species E. granulosus obtained by him from dogs in Pretoria and concludes that there are at least two and perhaps three species of Echinococcus in these animals whose description differs ...
  • A search for tick parasites in South Africa 
    Cooley, R.A.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    A detailed account is given of an expedition to South Africa undertaken by the author between 4th June and 17th October 1928 to obtain information on the parasites of ticks [ cf. R.A.E., B 18 1631.] A list is given of all ...
  • Studies on the photosensitisation of animals in South Africa. VII. The nature of the photosensitising agent in geeldikkop 
    Quin, J.I.; Rimington, C.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    The pigment responsible for the photosensitivity in geeldikkop and also that developing after operative ligature of the bile duct in sheep (experimental icterus) has been isolated and identified as phylloerythrin, a porphyrin ...
  • Isolation of the poisonous principle of Dimorphotheca cuneata Less 
    Marais, J.S.C.; Rimington, C.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    The toxic substance present in the plant Dimorphoteca cuneata has been isolated and identified as the cyanogenetic glucoside "linamarin" or acetonecyanhydrin glucose ether. An improved method of extraction has been described. ...
  • Anatomical studies, no. 46 : apus in a pig

  • Plant poisoning in stock and the development of tolerance 
    Steyn, D.G.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    From the results of experiments conducted upon thirty-two rabbits it appears (a) that the continuous ingestion of leaves or underground stems of gifblaar does not induce the development of tolerance to this plant; and (b) ...
  • The influence of feed on the Merino sheep 
    Mare, G.S.; Bosman, V.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    The influence of feed on two groups of Merino hamels which were given different quantities of lucerne, mealies, oats, and saltbush was studied. The body weights of the sheep were reduced by 15.8 per cent when the feed was ...
  • Recent investigations into the toxicity of known and unknown poisonous plants in the Union of South Africa 
    Steyn, D.G.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    The toxicity of fourteen plants were investigated. The symptoms and post mortem appearances caused by three plants, which have previously not been proved poisonous, are described. These three plants are (a) Epaltes alata ...

    This is a review and, as stated in the introduction, the author confines himself to certain aspects of the subject only - the modern conception of the individual identities and interrelationships of the serum proteins apart ...
  • Anatomical studies, no. 43 : two cases of missing incisor teeth in the horse 
    Curson, H.H.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)

  • Anatomical studies, no. 41 : prenatal death in the Merino ewe, associated with deformity of the cervix uteri 
    Curson, H.H.; Belonje, C.E; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    Attention is drawn to the somewhat frequent occurrence of prenatal death in the pregnant Merino ewe, and to a case of unusual cervical dilatation.
  • Handling mosquitoes for experimental purposes under South African conditions 
    Du Toit, Rene-Marie; Nieschulz, O.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)
    In the course of experiments on the transmission of horse-sickness and blue-tongue of sheep [ cf. preceding paper], it was found necessary to evolve methods for rearing mosquitos, feeding them on experimental animals and ...
