GENERAL ROUTINE WORK 53 the siluroid fish, which appear there in the rain pools. At other times they lie perdU m the sun-baked mud. I do not know if they serve as food. Scarification is practised as a remedy. Very few attempts at segregation have been made, but lepers labour under certain restrictions.

• ■FaM’'s-‘7CaPtam Ensor, who has had considerable experience of this disease in West Africa, tells me that he has seen one undoubted and one doubtful case at Kassala. In both instances children were affected. He suggests that the introduction of the disease into this part of the Sudan is due to the Hausa pilgrims on their way to Mecca.

Dhobie Itch (Harvard). Quite common, especially in the Southern Sudan. Chrysarobin is found the most effective remedy.

Keloids. Huge keloids occur as the result of syphilitic and other ulcerations. The Sudanese seem specially liable to such disfiguring overgrowths.

Kordofan Sores (Kurrha).—These are stated to be of the nature of veldt sores, and occur chiefly on the hands. It will be interesting, in view of Wright’s discoveries in connection with Delhi boils, to see if Leishmania Donovani exists in the basis of these sores.

Myiasis. The larvas of flies are sometimes found subcutaneously in the Bahr-El-Ghazal. No specimens have been sent me. Myiasis is common in the domestic animals, especially the camel, mule and horse.

Leueoderma. Seems to be rather frequent. May in some cases be the result of syphilitic infection.

VI.—Diseases Detected by a General Examination of the Body Beri-Beri.—Occurs. I saw a case in Omdurman which I suggested might be beri-beri. Dr. Christophers on was inclined to regard it as a neuritis dependent on diet. Captain Ensor tells me that he has seen two typical cases in the Sudan.

In Kordofan there is a peculiar disease, evidently a neuritis, known by the Arabic name for a haltered camel. Is this beri-beri, lathyrism, or the akatama described by Wellman1 amongst the Bantus?

Sleeping Sickness.—So far unrecorded. As stated, Glossina palpalis has not yet been found in the Sudan.

Low Fever.—Occurs. A kind of simple continued fever which is not enteric. May be due to the B. coli communis. During the hot weather there is a so-called Khartoum fever, which is fairly sharp, but only lasts a week or ten days. It is not malarial, but it is amenable to quinine. Possibly exposure to the sun and fatigue are the predisposing, if not the exciting, causes.

Malta Fever.—Has been described, but is certainly very rare, at least in its typical form.

Heat Stroke (Darbit liarrarar).—Not very common, but may be fatal, as in the case of a British soldier last summer. Red or rather orange covering 1 Journal of Tropical Medicine} September 1st, 1903
