70 PASTEUR AND AFTER PASTEUR 



scientific research, men and cattle can now live 

 there." 



From anthrax, Pasteur went on to the study of 

 swine-erysipelas, rouget, mal rouge. Thuillier, in 

 March, 1882, had discovered the germs of this 

 disease: and, in November of that year, Pasteur 

 and he began to work out a method of protective 

 treatment. But the rush of graver affairs in Paris, 

 and the death of Thuillier he went on the cholera- 

 expedition to Egypt, and died of cholera, in Alex- 

 andria delayed the study of rouget. Still, by 

 1886, the work was done. Chamberland in 1894 

 reported as follows : 



" Some years after the discovery of vaccination 

 against charbon, M. Pasteur discovered the vaccine 

 for a disease of swine known under the name of 

 rouget. From 1886, these vaccines were sent out 

 under the same conditions as the vaccines against 

 charbon. . . . The total average of losses during 

 the past seven years is 1*45 per cent., or about 

 1J per cent. This average is appreciably higher 

 than the average for charbon. But it must be 

 noted that the mortality from rouget among swine, 

 before vaccination, was much higher than that from 

 charbon among sheep. It was about 20 per cent. ; 

 a certain number of reports speak of losses of 

 60 and even 80 per cent. : so that almost all the 

 veterinary surgeons are loud in their praises of the 

 new vaccination." 



More than 10 million doses of this vaccine have 

 been sent out from the Institute. (See the Revue
