THE BACTERIA IN CONTAGIOUS MALADIES. 165 



and a third, with serum. The result of these three 

 inoculations was completely negative. The micro- 

 scopic examination by Charpy and Colrat did not 

 reveal the presence of any vibrionien. On the 

 16th of July, the patient left the hospital cured. 

 Let us add that the interne of the service, having 

 punctured his finger with a syringe employed in 

 making injections of carbolic acid (twenty per 

 cent), did not experience any ill effects. 



Darreau, veterinarian at Courtalain, attributes 

 to bad food this variety of charbon, in animals, 

 without the presence of bacteria. He has de- 

 scribed an epidemic on a farm where the forage 

 was of bad quality. Charbon is then due, ac- 

 cording to him, to impoverishment of the blood. 

 Decroix, veterinarian in the army, has examined 

 with the microscope the blood of horses submitted 

 to his observation, from the jugular vein, and also 

 the tumors. He has never found any bacteria. The 

 horses have recovered. These experimental and 

 clinical results have permitted Bouley to estab- 

 lish the unity of the charbonneuse malady, contrary 

 to the opinion of Prof. Bouillaud, who renews 

 the hypothesis of a multiplicity of charbonneuse 

 affections. 



In effect we see the same bacterium everywhere 

 producing the same disorders. In the very rare 

 and generally favorable cases of charbon which do 

 not seem to be of bacterial origin, we may say 

 with Pasteur, " When the parasite has not been 

 perceived, it is probably because sufficiently high 

 powers have not been used. The phlogogene ac-
