studies of the nature of this disease ? Accurate 

 diagnosis has been established; and the treat- 

 ment, worked out by Pasteur, is yearly saving 

 many lives. Every large city now has a Pas- 

 teur institute for the treatment of hydrophobia. 

 Since the inauguration of the Pasteur Institute 

 in Paris in 1886, there have been treated 31,330 

 cases, of which 238 died. The highest mortality 

 was .94 of 1 per cent, at the beginning, which 

 has since been reduced to .18 of 1 per cent. 

 Out of 4516 persons treated, who had been 

 bitten by dogs in which rabies was positively 

 proved, there were 34 deaths a mortality of 

 .75 of 1 per cent. 



In the Pasteur Institute at Baltimore 632 

 of the first 1000 persons treated had been 

 bitten by animals which were proved to be 

 rabid by (a) the development of rabies in rab- 

 bits inoculated from them, or by (b) the de- 

 velopment of rabies in other animals or human 

 beings bitten by them. But two of the patients 

 who completed the treatment for immunity 

 died a mortality of .2 of 1 per cent. At St. 

 Petersburg 2000 people are treated annually. 



Thus on the whole the mortality among 

 persons bitten by rabid animals has been re- 

 duced from 10 or 20 per cent, to a fraction of
