general routine work 51 Diseases Appearing from an Examination of the Faeces Dysmtery (Dorontaria) 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 weather, when there is a greater change between the day and night temperatures. It ' is probably amoebic in type, though it is likely that irritating sand particles and chill play a more important part in its production than does the Amccba coll Ankylostomiasis (Ankylostoma).—Common amongst the Egyptian soldiers and often very severe. Does not seem to be indigenous in the Sudan Ascaris lumbricoides (Tabaan el buttu).—Common, especially amongst gyptian soldiers. These fellaheen seem to be very favourite hosts for parasites of all kinds.

Tcema (Dooda walieeda).—I have only seen T. saginata. Multiple infection occurs.

Oxyuns vermicularis (Wooda Khatya).—Yerj common. Its ova are very liable to be confounded with those of the Ankylostomum. I have found the difference m the shape (the ova of Oxyuris being more curved on one side than the other) to be the best guide.

Tricliocephalus dispar has not been met with.

ScJiistosomum hcematobium.—Ova with laterally placed spines are common in the fasces of Egyptian soldiers.

Chronic Diarrhoea.—No opinion can be given. Sprue.—Apparently unknown.

III. Diseases Appearing from an Examination of the Urine Hcemoglobinunc Fever (Hummet el rnayiah el iswid).—I have only seen one case, and that was in a Greek at Gondokoro, in Uganda; but at Rejaf (Lado Enclave) I met a young 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 Bahr-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, however, significant that the natives of the Golo tribe have a special remedy for this disease.

Endemic Hcvmaturia (Billiarzia).—Of frequent occurrence amongst the -SyPan 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. None of the three had ever been out of the Sudan. The chief point of significance lay in the fact that all three drank water from a school well in Khartoum. So far nothing suspicious has been
