Tsetse-fly." In. the same year Dr. Max Schoeller [167], writing 

 on German East Africa, suggested that should the domestication 

 of zebras for transport purposes prove feasible, those animals 

 would be of much more use than horses or donkeys owing to 

 their immunity ivom Tsetse-fly disease. Dr. Schoeller also dis- 

 cussed the question of the possible identity with the Tsetse of 

 the " Wandorobo-fly " of the Wadschagga, the bite of which was 

 stated by the latter to have been responsible for the death of his 

 donkeys, though attempts to obtain specimens of the fly proved 

 unsuccessful. The author in question seems inclined to believe 

 that his donkeys really died from a form of the disease known to 

 the Boers as " Dikkopziekte " — the South African horse-sickness. 

 Among other publications of 1901 to be noticed, is a " Report by 

 His Majesty's Commissioner on the East Africa Protectorate" 

 [168], in which it was stated that since the advent of the Uganda 

 Railway horses can be brought up from the coast to Ukamba for 

 travelling purposes, while formerly it was the custom in that 

 country " to make long marches on foot," owing to the impossi- 

 bility of conveying horses from the coast through the intervening 

 Fly-belts. The Commissioner supports Dr. Schoeller [167, vide 

 supra] by advocating the domestication of the zebra and the 

 wildebeeste, and for the same reason, adding that " the pi-osperity 

 of the country is at present sadly hampered by want of eflicient 

 transport." In the same year Mr. and Mrs. Hinde [169], in 

 "The Last of the Masai," expressed the fear that the establish- 

 ment of the Uganda Railway might contribute towards the final 

 extinction of big game " in the last stronghold left in Africa," 

 since now that the barrier formed by the Tsetse-fly was no longer 

 an obstacle it was possible for " vsportsmen " to enlist the aid 

 of the horse. Towards the end of 1901 Dr. Schilling [170] 

 recorded the presence of a disease which is fatal to horses and is 

 called by Schilling "Surra" (no doubt in agreement with Koch, 

 who pronounced Tsetse-fly disease in East Africa to be identical 

 with Surra in India), in the German Protectorate of Togo, on 

 the Slave Coast, West Africa, where, as is shown in Chapter IV. 

 of the present work, Glossina morsitans occurs, as well as GL 

 palpalis and GL fusca. Schilling was unable to make experiments 

 with the fly, but described the Trypanosoma which causes the 

 disease. 



Turning to the year 1902, an important work by MM. 

 Laveran and Mesnil [171] must be noticed, since besides treating 

 of the hsematozoa of Nagana and kindred diseases, it contains
