GENERAL ROUTINE WORK 53 



the siluroid fish, which appear there in the rain pools. At other times they he 

 perdu in the sun-baked mud. I do not know if they serve as food. Scai'ification 

 is practised as a remedy. Very few attempts at segregation have been made, but 

 lepers labour under certain restrictions. 



Yaws. — Captain 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 ( Harrara). — 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 vdcerations. 

 The Sudanese seem specially liable to such disfiguring overgrowths. 



K or do fan 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 Dellii boils, to see if Leishmania Donovani exists in 

 the basis of these sores. 



Myiasis. — The larva? 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. 



Leucoderma. — 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. — Occm's. I saw a case in Omdurman which I suggested might be 

 beri-beri. Dr. Christopherson 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 nem'itis, known by the 

 Arabic name for a haltered camel. Is this beri-beri, lathyrism, or the akatama 

 described by Welknan' amongst the Bantus? 



Sleejnng 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 

 Khai-toum 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 Jiarrarar). — Not very common, but may be fatal, as 

 in the case of a British soldier last summer. Red or rather orange covering
