— 68 — The tour of a Syrian medical officer round all the villages along the river north of Khartoum during January and February was extremely successful, nearly 3,000 cases of malaria were treated and 1,000 cases of other diseases.

The splenic index of 16 villages varied from 65 p.c. to 100 p.c. in one case, a state of affairs which clearly calls for stringent anti-mosquito action and intensive treatment of the carriers.

The dispensary at Geili continues to do most useful work, 6,467 persons received treatment during the year.
