10 DISEASES OF SHEEP AND GOATS.

Sheep Pox.

Cases of this disease occurred amongst sheep imported from Darner, at the Haifa Quarantine, and a few cases were reported amongst Sudanese sheep imported into Egypt.

Contagions Pleuro-pneumonia of Goats.

This disease, known as Abu Neeni amongst the natives, has been the cause of considerable losses amongst goats, particularly in the neighbourhood of Geili in Khartoum Province. Experiments were carried out by the Veterinary Bacteriologist, with a view to obtaining a satisfactory material for preventive inoculation, but without success. Owners appear to appreciate the value of early isolation of the infected from the apparently healthy as a preventive measure.

VETERINARY SURVEY SECTION.

Captain R. H. Knowles, Royal Army Veterinary Corps, has been in charge of tins Section during the time he has been in Khartoum.

He was absent for a considerable period in Kenya Colony, and on leave : but, nevertheless, much valuable work has been done during the year. 585 smears and specimens have been examined and reported on in the laboratory, from horses, mules, donkeys, camels, cattle, sheep, dogs and birds. Various vaccines were prepared, and research work followed the lines of endeavouring to discover a cure for 'Trypano¬ somiasis, for Epizootic Lymphangitis, and to ascertain the cause ot Infectious Pleuro-pneumonia of goats.

Captain Knowles has lately been fortunate in obtaining a despatch of “Bayer 205", the most recent drug for the treatment of Trypano¬ somiasis, from the German discoverers. This drug is not yet on the market, and the quantity being sent is for experimental purposes.

It is hoped that the drug will prove as efficacious as it is reported to be.

Recently some test experiments have been carried out for the purpose of studying the respective immunising powers of Indian and Italian anti-anthrax serum.

Experiments are now in progress in order to discover the suscepti¬ bility of half-bred Sudan cattle to Rinderpest, and to ascertain the possibility of using them as anti-rinderpest serum producers.

Further experiments are following the lines of the manufacture of Contagious Bovine Pleuro-pneumonia vaccine.
