166 PHYSIOLOGY OF THE BACTERIA. 
tion of the bacteria, brought to light by Toussaint, 
is necessary in order to explain the production of 
the tumors of charbon.” 
Davaine, in consideration of the immobility of 
the Bacillus anthracis, admits that. every tumor 
results from a local inoculation. We have called 
attention to the fact that the virulent agents of 
variola and of rugeola, although motionless, pro- 
duce nevertheless local manifestations. In the 
second place, the charbon of the horse is often 
accompanied by internal tumors of which the or- 
igin evidently cannot be an external cause.  Fi- 
nally we have pointed out by Bouley some horses 
of La Plata in which the local manifestations 
did not appear until after the general symp- 
toms. ‘This view had already béen sustained by 
Chabert. However, notwithstanding all the proofs 
furnished turn about by experimental pathology and 
clinical study, one desideratum still remains. It 
is necessary to verify the presence of the spores 
of Bacillus anthracis in the lands where charbon 
prevails as an epizootic and to discover its means of 
transportation. 
Before abandoning this question, we think it 
proper to examine the efficacy of antiseptic treat- 
ment. Carbolic acid, studied by Koch, has been 
employed with success; boracic acid, which acts 
upon the bacteria by depriving them of oxygen, 
has been utilized by Decroix, veterinarian of the 
army; tincture of iodine, employed, like carbolic 
acid, — by subcutaneous injections,— has given 
rise to grave accidents. Beside these general
