Extension of 



In the bacteriological laboratory attention has been chiefly directed to the question of 



trypanosomiasis in equines and cattle and to the discovery uf a new blood parasite, a 



IIaino<jrcijarine, in the jerboa or desert rat. A somewhat similar parasite has also been 



found in the Norway rat. A full account is given of these researches. Mosquito work has 



been steadily continueil, some attention has been paid to bilharziosis in the Sudan, and there 



has been a great deal of clinical work for the hospitals and sanitary work for the town 



generally. Insect pests and grain diseases have also come under notice and the value of 



zeers as bacteriological filters is at present being determined. 



I have to report that there has been an extension in tjie i)reiiiises. The Director of 



premises 



Education kindly granted tlie use of two extra rooms. One of tliese has been converted into 

 the Director's office and accommodates the library ; to the other which adjoins it the 

 laboratories' museum has been transferred. It is thus next the kitchen and preparation 

 room and is more conveniently situated, while the re-arrangement has enabled the old 

 museum room to be attached to the Chemical Department. Dr. Beam has fitted it out as a 

 water analysis room ami place for standing apparatus, and there is no doubt it was urgently 

 needed. He has also altered and re-furnished the main Chemical Kooni to meet his 

 requirements. 



This year the laboratories were fortunate enough to receive a grant of £E 322, which Special grant 

 enabled special chemical apparatus to be obtained and new books and periodicals purchased. 

 Some bacteriological equipment was also added and breakages were made good. Our small 

 annual contingent was quite insufficient to meet these necessities. 



The library, though still far from perfection, is fairly well supplied, ami the number of '^'"'^ library 

 scientific journals taken in or presented has undergone considerable addition. 



The museum has markedly increased in pathological material, biting flies, ticks 

 and mosquitoes. Not many new native drugs have been added. A few were sent by Museum 

 Captain Ensor from Suakin. It is impossible to mention all those who have benefited the 

 museum, but I would like specially to thank Colonel Penton and Colonel Hunter, the past 

 and present Principal Medical Officers, JIajor Bray, Captain Nickerson and Captain Hughes 

 for specimens of biting diptera, and Major Dansey Bro%\-ning, Mr. Crispin, Mr. Waterfield, and 

 Captain P. E. Yaughan for valuable pathological material. Mr. Crispin has also furnished 

 interesting photographs of various diseases. I regret that the beautiful series given by 

 Dr. Christopherson during the first year of the laboratories' existence has not been further 

 augmented. 



Colonel Griffith, Captain Head and Mr. Thomas have continued generous donors 

 and there is quite a respectable veterinary pathological department now in existence. 

 Mrs. Broun has rendered much valuable help in the identification of ticks, many of 

 which were sent by Mr. Gorringe. Sir Rudolph von Slatin kindly presented a goat 

 showing an interesting malformation. 



Other gifts have to be recorded. Besides elastic dust-proof Bookcases for 

 the library Mr. ^Yellcome presented a valuable Stereoscopic Camera — a most useful 

 apparatus, in view of Dr. Beam's ability as a photographer, while the outfit which he 

 provided for Dr. Neave's expedition was most complete and comprehensive in every respect. Gifts to the 



Mr. Macmillan, at the close of his Expedition, very kindly handed over a fine Zeiss ''^b"^*'""" 

 microscope adapted for photographic work. It has proved of great service. 



It is again a pleasure to state that medical officers stationed in Khartoum have freely
