    Sex physiology of sheep
    (Pretoria : Government Printer, 1936) Roux, Lucien L.; Du Toit, P.J.
    The incidence of infertility among domestic animals has been the greatest stimulus towards researches upon the pathology of the genitalia of these animals (Quinlan, 1929, 1935). However, it has been realized for many years that factors also of a non-pathogenic nature are responsible for many irregularities which occur in connection with the functions of the sex organs of farm animals (Heape, 1899, 1901; Marshall, 1903; Hammond, 1914, 1921; Marshall and Hammond, 1926). Detailed studies of sex physiology are elucidating problems which, if solved, would assist farmers in regulating the management and feeding of their stock so as to obtain maximum production during the full length of the normal life of their animals. Any degree of infertility means economic loss; moreover, the presence of inherent low fertility is transmitted to subsequent generations (Crew, 1925).

    The incidence and pathology of tumours of domesticated animals in South Africa : a study of the Onderstepoort collection of neoplasms with special reference to their histopathology
    (Pretoria : Government Printer, 1936) Jackson, Cecil; Du Toit, P.J.
    Since the inception of a routine pathological diagnostic service at Onderstepoort over 18,000 pathological specimens have been submitted for histological diagnosis over a period of some fifteen years. Much of this material had been earmarked as of interest for further examination or for museum purposes and among it occurs a wealth of examples of neoplastic disease in the domesticated animals. The present work is the result of a programme to make this material conveniently available for reference and further study, whereby it is proposed to establish a complete collection of microscopic preparations representative of the pathology of domesticated animals in this country serving at once as a check on the accuracy of the diagnosis of the macroscopic specimens in the extensive museum of pathology which has been built up at this and supplementing the study of this material from the histological standpoint.

    Researches into sterility of cows in South Africa : the Influence of (i) dry rations, (ii) lack of exercise, and (iii) lack of sunlight on reproduction in beef heifers and cows
    (Pretoria : Government Printer, 1936-04) Quinlan, John; Roux, Lucien L.; Du Toit, P.J.
    The effects of a dry ration, high condition, the absence of sunlight, and exercise upon the sexual activity and reproduction of beef females have been studied. The results obtained during six years of observations are reported upon; the period includes four calvings.
