M.D. (Department of Education, Khartoum.)--Mr. Henry S. Wellcome generously equipped
these laboratories at his own expense. Dr. Balfour arrived to take charge of them in January, 1903. His staff consists at present of an assistant and two Soudanese, " one of them a small boy." A second assistant, a chemist, is to be, or has been, added ; the Director pleads for a, further addition, a collector, "a trained observer whose duty it would be to traverse the country and collect blood films, biting and injurious insects, parasites, photographs of pathological con- ditions among the natives, drugs, poisons, and, indeed, anything having a bearing on tropical medicine in the Sudan." We quote these words because they indicate the nature of the work done. In illustration of the " biting and injurious insects " there is an account of "mosquito work in Khartoum, &c." Mosquitoes are not the only creatures of this kind. There are also insects and vegetable parasites injurious to crops,—these are figured in the Report. Then comes a report on a curious phenomenon, the generation of hydrocyanic acid in fodder (sorghum vulgare). And there are some details of observations of disease.
