56 n: i. he or PASTEUR 



The Academy d 1 that the necropsy and miscroscopic 



examination of the i hen which Pasteur was to bring to 



Colin should take pi • in the presence of a Commission com 



''d of Pasteur, Colin, Davaine, Bouley, ;ind Vulpian. This 

 Commission met on the following Saturday, July 20. in the 

 Council Chamber of the Academy of Medicine. M. Armand 

 Moreau, a member of the Academy, joiin-d the five members 

 pn a partly out of curiosity, and partly because he bad 



special reason! for wishing to speak to Pasteur after the 

 me.-ti' 



Three hens were tying on the table, all of them dead. The 

 first one had been inoculated under the thorax with five dropi 

 of yeast water slightly alkalized, which had been given as a 

 nutritive medium to some bacteridia anthraeis ; the hen 

 had been placed in a bath at 25° C. and had died within 

 twenty-two hours. The second one, inoculated with ten drops 

 of a culture liquid, had been placed in a warmer bath. 30° C, 

 and had died in thirty-six hours. The third hen, also 

 inoculated and immersed, had died in forty-six hours. 



I. Bides those three dead hens, there was a living one which 

 had been inoculated in the same way as the first hen. This 

 one had remained for forty-three hours with one-third of its 

 body inm I in a barrel of water. When it was seen in the 



laboratory that its temperature had gone down to 36° C, that 

 it was incapable of eating and aeemed very ill, it was taken out 

 of the tub thai very Saturday morning, and warmed in a stove 

 at 4-2° C. It was now getting better, though still weak, and 

 gave signs of an excellent appetite before leaving the A I my 

 council chamber. 



The thud hen. which had been inoculated with ten drops, 

 was dissected then and there. Bouley, after noting a sen 

 infiltration at the inoculation fo :owed to the judi 



sitting in this room, thus suddenly turned into a testing labora- 

 tory, numerous bacteridia ttered throughout every part of 

 the hen. 



' After those ascertained results," wrote Bouley, who drew 



up the report. " M. Colin declared that it was useless to pro- 

 C 1 to the necropsy of the two other hens, that which had just 

 b u made leaving U0 doubt of the presence of bacilli anthraeis 

 in the blood of a hen inoculated with charbon and then placed 

 un ler the conditions designated by M. 1 - as making 



inoculation efficacioi
