mill other tribes iiihiibitiiig that rugioii. Trnv I liml not fuuml tlic tly in tluso parts, hut my 

 observations hud been very limited, and a thorough examination was most necessary. Tinit 

 sneh was the ease was speedily provid by the news that Captain Greig of tiie Koyal 

 .Society's Coininissiim in Uganda, Inid been deputed to travel iiortli and examine both banks 

 of tile Nile not only in Uganda bnt in the Sudan. It so happened that Dr. Neave was able 

 to meet him at Gondokoro and eo-operate with him. ('aptain Greig being pressed for time 

 did not exteiiil his observations furtlur lliaii Uni-. 1 Ir. Neave made a more lengthy 

 exploration and his results, being negative, coincide with those alreadv published by 

 Dr. (}reig. Dr. Neave then nianhcd tliiough a portion of the ]5ahr-EI-(iliazal province 

 finding (J. morsitaiiK present but no sign (if (i. ji(i/j>ali.i. 



In additidU, Dr. Neave made many bltiod exaiiiinatidiis and (liscovered new 

 trypanosuiiu's in tisli ami lijnls. He aiso f(aniii (itiicr iilooil parasites which are 

 tle.scribed and tigure<l in liis licpurt ; Captain (!nig Idmlly cummitted to his care a 

 Uganda boy sufl'ering from tiypanosomiasis, ami Dr. Neave was able to test the effect of ii 

 new therapeutic agent, wliidi has also been Iried in cases of animal trypanosomiasis in the 

 laboratories. 



Several new mos(]uitoes were taken by Dr. Neave, and he brought back a collection 

 of biting flies, native drugs and other specimens of interest. 



His expedition has, therefore, been product ive of valuable scientific results, and he has 

 obtained useful information for the Government. 



From evidence supplied by JIajor Bray of the Egyptian Jledical Service it is evident 

 that the danger is to be looked for in the direction of the Congo Free State and Bahr-El- 

 Ghazal province, a point to wliirli allusion will be made later. The discovery of d'. .\[nrsiliiiis 

 by JIajor Jlorant in Southern Konlofan is another fact of somewliat ill-omened interest. 

 At the instance of the Sudan Commi.ssion on Sleeping Sickness, JIajor Dansey Browning, 

 of the Egyptian Jledieal Service has been sent in charge of an Expedition to observe and 

 report in the southern part of lln- ISahr-El-Ghazal luovince. These laboratories have 

 supplied the scientific outfit for this work.* 



At the end of 19U4, Jlr. Newluve terminated his connection with the laboratories, being 

 appointed Sanitary Inspector for Khartoum. His work with the mosquito brigade had 

 specially fitted him for sudi a jiost. His place was taken by Jlr. H. K. Fiiedrichs, who 

 came with good credentials from Leith Technical College and elsewhere. 



The stafl" has also been increased by the appointment of a clerk in the person of 

 Mahmoud Etl'. Khalil, a late iiupil of tlie College who has completed his training. This has 

 considerably lightened the ollice and clerical work which was fast becoming a buriKii and 

 greatly interfered with research. 



• Hi» K.xcellency. the Governor Qeiieral of tlie Sudan, has directed that a Commission \k appointed to 

 investi(;ate the possibility of the e.vtension of "Sleepiiii: Sickness" into Sudan Territory. The Coniniission to he 

 as follows:- Lieut.-Colonel O. D. Hunter. D.S.O., P.M.().K..\., Dr. .Vndrew Balfour, Director of the Wellcome 

 Itesearch I.ialionitories, Khartoum, A British Medii-il Ollieer, Eiryptian Army, or Medical Inspector, Sudan 

 Medical Dept., or such nicml)crs as may be hereafter appointed. 



Points to be Investigated. 



1. To ascertain the distribution of various species of t.sciso flies or other biting flies in the Sudan. 



2. To a.s<^-rtain if the disease at present exists in Sudan territory. If sti, to determine the exact areas — 



and to what e.\teut the distribution of the disease coincides with tlie preseiKT of the tsetse or 

 other Hies in these areas. 



3. A systematic investif;atiou of the blood and lymph glands of a population in an infected district. 



4. A thoroutrh and complete research into the character of the disease, especially as regards itsorigin and 



spread.
