15— BACILLUS ANTHRACOIDES IN TRANSVAAL 

 WATER SUPPLIES. 



By F. H. Josephs. 



[Abstract.] 



The "■ Bacilhis anthracoides of Huppe and Wood," which 

 Avas originally isolated from soil, and appears to stand midway 

 l^tween B. subtilis and B. anthracis, has been isolated in the 

 Transvaal thirteen times from surface wells, from three different 

 streams, on three occasions from sewage effluents, from soil, from 

 dam water, but only once from water from a deep borehole by the 

 author. 



[The microscopical appearances, cultivations, and pathogenicity 

 of the bacillus, were described.] 



From the knowledge otherwise gained concerning the waters 

 from which this bacillus has been isolated, the author concludes that 

 the presence of B. antJiracoides in a water-supply is stronglv sug- 

 gestive of contamination, and he is of opinion that the detection of 

 this organism may be of considerable importance in the study of 

 water-supplies, especially in those cases in which pollution occurs at 

 comparatively long intervals.
