THE BACTERIA IN CONTAGIOUS MALADIES. 163 



(July 30 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 phlogogene 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 phlogogene 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 Vibrion aerobie. 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
