belongs to the surra group, greatly resembles the trypanosomiasis 

 of the Somali dromedaries, called " salaf " {op. eif., vol. xxi., 

 p. 453). 



An easy way of differentiating the two kinds of Eritrean 

 trypanosomiasis is by inoculation of a full-grown dog and a sheep. 

 The dog will remain perfectly healthy if inoculated with 

 "jahan," but will fall seriously ill if " atteh " be transfused; 

 " jahan," on the contrary, will cause the sheep's death in a few- 

 days, while "atteh" will leave it nearly normal. 



La chasse aux Mouches et les Fumiers. [The destruction of flies 

 in relation to manure heaps.] — Le Monifevr (VRorticvlfvrc. 

 Paris, no. 17, 10th Sept. 1913, p. 194. 



In an editorial, attention is drawn to a circular, issued by the 

 French Ministry of Agriculture to the Directeurs des Services 

 Agricoles Departementaux, enjoining them to take such steps 

 as may be possible to spread a knowledge of the harm done by 

 flies to human beings and simple methods for their destruction, 

 more especially the destruction of the larvae in manure heaps 

 by the use of petroleum, cresyl and other active disinfectants. 

 It is pf)inted out that the lavish use of these disinfectants, 

 though fatal to the flies and their larvae, renders the manure 

 unfit for garden use and especially for the cultivation of plants 

 in frames laid upon hot-beds of such manure; and it is said that 

 it lias been experimentally proved in the neighbourhood of 

 London that manure which has been treated with disinfectants 

 regardless of quantity, is unfit and even harmful for such methods 

 of cultivation. The writer of the article vsays that milk of lime, 

 smnll quantities of sulphate of iron or alkaline solutions may be 

 employed without spoiling the manure, but thnt all petroleum 

 derivatives and the like should be proscribed.

The author considers that in view of the erroneous impres- 

 sions which prevail on the distribution of sleeping sickness in 

 Southern Rhodesia, it is desirable to give a somewhat detailed 

 nccount of it and of the distribution of the fly. 



The only variety of Glossina found in vSouthern Rhodesia is 

 G. morsitans, and its hnbitats are limited in area. Tlie fly- 

 areas are small in extent, as compared with the country. Tliey 

 lie in the northern part of the territory and are widely scat- 

 tered, thus difl'ering from the distribution of the tsetse in Central 

 and Equatorial Africa. Our knowledge of the bionomics of the 

 fiy is still too limited to supply any satisfactory explanation as 

 to v.hy the tsetse should bo confined within tliese somewlmt 

 arbitrary boundaries, when topograpliically and climatically 

 there are stretches of country to all uppearnnce similar, for it
