THE BACTERIA IN CONTAGIOUS MALADIES. 160 
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 phlogogeéne ac-
