Abstract
THE eighteenth report of the Director of Veterinary Services and Animal Industry, Onderstepoort, Pretoria, contains matter of value to the veterinarian and agriculturist. Several papers deal with parasitic and virus diseases of animals, and considerable space is devoted to the subjects of mineral deficiency and metabolism and to plants poisonous to stock. Mr. Bedford contributes an exhaustive synoptic check-list and host-list of ectoparasites found on South African mammals, birds, and reptiles, and Mr. Steyn has continued his observations on the effect of sulphur on merino sheep. A ration of 5 gm. of sulphur thrice weekly improves the condition of the sheep and increases the wool yield from an average of 8–4 Ib. to an average of 11–625 Ib. It also increases resistance to prussic acid, and may be of value in reducing ‘geilsiekte’, a poisoning that arises from ingestion of certain plants in which a cyanogenetic glycoside is present. The report, in two parts, is admirably produced and illustrated (Government Printer, Pretoria, 20s.)
