M THE LIFE OF PASTEUR 



The old professors, whose career had been built on a com- 

 bination of theories which they were pleased to call medical 

 truth, dazed by 6uch startling novelties, endeavoured, at did 

 Piorry, to attract attention to their former writings. "It is 

 not the disease, an abstract being," said Piorry, " which we 

 have to treat, but the patient, whom we must study with th> 

 greatest care by all the physical, chemical and clinical me 

 which Science offers." 



The contagion which Pasteur showed, appearing clearly in 

 the disorders visible in the carcases of inoculated guinea-pigs, 

 was counted as nothing. As to the assimilation of a laboratory 

 iperiment on rabbits and guinea-pigs to what occurred in 

 human pathology, it may be guessed that it was quite out of 

 the question for men who did not even admit the possibility of a 

 comparison between veterinary medicine and the other. It 

 would be interesting to reconstitute these hostile surroundings 

 in order to appreciate the efforts of will required of Pasteur to 

 enable him to triumph over all the obstacles raised before him 

 in the medical and the veterinary world. 



The Professor of Alfort School, Colin, who had, he said, 

 made 500 experiments on anthrax within the last twelve years, 

 stated, in a paper of seventeen pages, read at the Academy of 

 ■ Medicine on July 31, that the results of Pasteur's experiments 

 had not the importance which Pasteur attributed to them. 

 Among many other objections, one was considered by Colin as 

 a fatal one — the existence of a virulent agent situated in th< 

 blood, besides the bacteridia. 



Bouley, who had just communicated to the Academy of 

 -ciences some notes by M. Toussaint, professor at the Toulouse 

 veterinary school, whose experiments agreed with those of 

 Pasteur, was nevertheless a little moved by Colin's reading. 

 He wrote in that sense to Pasteur, who was then spending his 

 holidays in the Jura. Pasteur add:- seed to him an answer as 

 vigorous as any of his replies at th< lezny. 



" Arbois, August 18, 1877. — My dear colleague ... I 

 hasten to answer your letter. I should like to accept literally 

 honour which you confer upon me by calling me 'your 

 master,' and to give you a severe reprimand, you faith-
