THE BACTERIA IN CONTAGIOUS MALADIES. 163 
(July 50 of the same year), recognizing that the 
persistence of the virulence is due to spores (cor- 
puscles germes) which resist all the causes of de- 
struction. 
Quite recently, finally, Toussaint, while studying 
the mechanism by which the bacteria cause the 
death of rabbits, horses, and sheep, arrives at the 
conclusion that it is because of asphyxia of me- 
chanical origin, — embolism of the pulmonary ca- 
pillaries. 
The phlogogéne action of the vibrionien is some- 
times such that, in addition to embolism, there is a 
rupture of the capillaries, and even lesions graver 
still. 
“The phlogogéne material is more active, accord- 
ing to the subjects from which the bacteria are 
obtained. The animals which I have studied may 
be arranged as follows: the rabbit, guinea-pig, 
sheep, ass, horse, dog.” As to the hog, it is not 
at all susceptible. 
In the last place, Toussaint has presented, through 
Bouley, a note upon a form of charbon caused by 
a Vebrion aérobie. This affection was already 
recognized as contagious, but the agent of conta- 
gion was not known. ‘Toussaint has found that it 
is caused by a Bacterium, differing in certain char- 
acters from Bacillus; he has cultivated this mi- 
crobe, and has seen it reproduce itself under the 
microscope, in an apparatus invented by Ranvier. 
The malady has been transmitted to rabbits in the 
same burrow without inoculation. 
By taking the excrement, reduced to powder, of
