(b) . Cattle could be bred from selected parents on an isolated farm with precautions against the introduction of the disease, so that the progeny bred there would be susceptible.

(c) . It the cattle in areas such as the Gezirah were protected as we recommended by double inoculation against Rinderpest, the young stock in these areas could be employed for the production ot anti-rinderpest serum. This is the method used in Kenya. The half-bred cattle from the settlers farms are used, as all the cattle belonging to the settlers are protected by the double inoculation method.

Experiments might prove that the young stock bred at the Dairy tarm in Khartoum would be suitable for the purpose of serum production.

We had the opportunity of studying the technique of the produc¬ tion of anti*rinderpest serum at the institute at Kenya.

3. EAST COAST FEVER.

This disease has not been reported in the Sudan, although it has been reported by Mason as occurring in Sudanese cattle exported to Egypt.

It is hardly conceivable that a few cases of this disease could occur, as a reference to the history of East Coast Fever in Africa shows that on its first introduction into a country the mortality amongst the cattle is enormous.

It first broke out in East Africa in 1900, and rapidly spread. It appeared in the Transvaal in 1905, and in that year 50,000 cattle died of the disease in that country.

It exists now in all East and South African countries and immense sums of money are now being spent on its control.

Our more recent knowledge would suggest that the cases reported as East Coast Fever from the Sudan were cases of Tropical Piroplasmosis, caused by the Piroplasma annulatum, which is reported to be very common in Egypt. The histology and morbid anatomy of these two diseases are very similar.

It appears to us, however, that East Coast Fever is a very important disease to the Sudan, as in Uganda the disease has spread Northwards and now exists on the border between Uganda and the Sudan. One has therefore to anticipate the possibility of its spread Northwards into the Sudan. We lake this opportunity of offering the suggestion that a veterinary survey of the Southern border of the Sudan be carried out,
