Finally, we Lave not merely confined ourselves to the ordinary 

 cultivation tests for ascertaining the vitality or otherwise of the 

 anthrax organism, under these several conditions ; hut we have also 

 submitted the virulence of the infected waters under investigation to 

 the direct test of inoculation into animals. 



Inasmuch as the investigation of the above points has been con- 

 ducted by each of us to a certain extent independently of the other, it 

 has been proposed to record our experiments separately also, as in this 

 manner the course of the two investigations is most easily followed, 

 and the results obtained most readily surveyed. In the following- 

 pages, therefore, will be found a separate account of the independent 

 inquiry pursued by each of us, the report closing with a number of 

 conclusions which we have together drawn from the experimental 

 material collected by both.
