Cure for Sleeping Sickness. — M. Danyez, in a 



paper recently presented to the Academy of Sciences, points out 

 the advantage, in treating trypanosomijisis. of using several 

 medicaments, no one singly being energetic enough to effect a 

 cure. Thus, in trypanosomiasis occasioned by the spirilla of 

 Rhodesia, very remarkable results have followed upon minute 

 doses of arseno-benzol and silver nitrate. A single injection of 

 one-twentieth of a mgrm. has cured a mouse ; similarly rabbits 

 have been cured by single injections of five mgrms. 



TRAXSACTIOXS OF SOCIETIES. 



South African In.stitute of Elkctktcal EiNcinekrs. — Thursday, 

 May 15th: J. W. Kirkland, President, in the chair. — "Water Power plants; 

 with special reference to the Belvedere Power plant, Pilgrim's Rest, Trans- 

 vaal" : W. Elsdon-Dewr. The author traced the development of electricpower 

 transmission in the Pilgrim's Rest District from 1890 up to tgio. when 

 the Belvedere Power scheme was decided on. The water race and power 

 station, completed in July, 191 1, were described. The intake is situated on 

 the Blyde River, above the Dientje Falls, which are 120 feet in height 

 The whole water race was designed for a flow of 160 cubic feet per second 

 at a velocity of two to three feet per second. From the gates the water- 

 way passes through an intake tunnel 445 feet in length through solid rock. 

 Three other tunnels are subsequently traversed, the longest being 1,090 

 feet in length. The power line, which is 19 miles in length, traverses 

 broken country for five miles after leaving the power house, varying 

 about 800 feet in altitude in that distance. 



Thursday, June 26th : J. W. Kirkland, President, in the chair. — "Notes 

 on the construction of the Victoria Falls Power Company's 80,000-volt 

 station at Vereeniging" : R. B. Canning. A detailed description of the 

 new power station at Vereeniging, comprising notes on the water supply, 

 method of handling coal, the boiler plant with economisers and super- 

 heaters, the boiler feed system, the steam ranges, steam and electrically 

 driven auxiliaries, the main turbo-generators, and the switch gear.
