II. — Diseases Appearing from an Examination of the Faeces 



DifHentery [Dorontana) is not very frequently seen. It is probably most 

 common in young British officers. Slight forms, the so-called dysenteric 

 diarrhoeas, occur. It seems to be more frequent in the hot Aveather, when there 

 is a greater change between the day and night temperatures. It is probal>ly 

 amojbic in type, though it is likely that irritating sand particles and chill ]>lay a 

 more important part in its production than does the Amoeba coli. 



Ankijloatoinia'iiv [Ankylo-'^toiiia). — Common amongst the Egyptian soldiers, 

 and often very severe. Does not seem to be indigenous in the Sudan. 



Ascarifi himbricoides [Tahaan el buttu). — Common, especially amongst 

 Egyptian soldiers. These fellaheen seem to be very favourite hosts for parasites 

 of all kinds. 



Tcenia [Douda icakeeda). — I have only seen T. .sayinata. Multiple infection 



OCCUl'S. 



Oxyuris cer/nicidaris ( Wooda Kliatya). — Very common. Its ova are very liable 

 to be confounded with those of the Ankvlostomum. I have found the difference 

 in the shape (the ova of Oxyuris being more curved on one side than the other) 

 to be the best guide. 



Trichocephalus dispar has not been met with. 



Schistosomum hcematobium. — Ova with laterally ^slticed spines are conmion in 

 the fasces of Egyptian soldiers. 



Chronic Diarrhoea. — Xo opinion can be given. 



Sprue. — Apparently imknoAvn. 



III. — Diseases Appearing from an Examination of the Urine 



Hcentoglobinuric Fever (Huiiunet el mayiah el isvid ). — I have only seen one 

 case, and that Avas in a Greek at Gondokoro, in Uganda; but at Kejaf (Lado 

 Enclave) I met a yotmg Scotchman who had just recovered from a second attack. 

 Although not charted in Scheube's map, blackwater fever does occur in the Sudan. 

 Capt. Rivers, E.M.C., reports that no case has yet occurred north of 10° N. lat. 

 The disease seems confined to the White Nile regions south of Fashoda, and to the 

 Bahi--El-Ghazal province. British officers and Egyptians form the majority of the 

 victims, and since the reopening of the country these have been few in number. It 

 is, howe\'er, significant that the natives of the Golo tribe have a special remedy for 

 this disease. 



Endemic Hcematuria (Bilharzia). — Of frequent occurrence amongst the 

 Egyptian soldiery. Was supposed not to exist in the Sudan, save such cases as 

 had acquired infection in Egypt or elsewhere. Recently the urines of three 

 Sudanese boys have been sent to the laboratories. All three showed blood, pus 

 and the characteristic ova. Two were brothers. Xone of the three had ever been 

 out of the Sudan. The chief point of significance lay in the fact that aU three 

 drank water from a school well in Khartoum. So far nothing suspicioits has been
