the very rapid tympanitic swelling of animals dead with septicae¬ 
mia and the emphysematous state of the cellular tissue, especially 
in some points of the body, the groins and axillas, where the in¬ 
flammation is sometimes excessive. 
I must add, without waiting any longer, that all of the vibrios 
are not anaerobic; that one of the most common, for instance, 
which is frequently found at the surface of the infusions of the 
vegetable organic substances exposed to the contact of the air, 
vibrio very fluxuous and very quick in its motions, is exclusively 
aerobic. It absorbs oxygen and exhales carbonic acid nearly in 
equal quantity, thus reversing the physiology of the carbuncular 
bacteridie. 
Short of time, I will only mention, in passing this vibrio— 
because it has been for us the source of very interesting observa¬ 
tions—it is inoffensive. Introduced under the skin, it gives rise 
only to local troubles of little importance. Comparing its inno- 
cuity to the virulency of the septic vibrio, one might believe that 
the mode of life, so different for both, as one is aerobic and the 
other anaerobic, would explain the opposition of the actions upon 
the economy. But the effects of the carbunculous bacteridie 
which, also, is essentially aerobic and nevertheless terrible, would 
not permit to accept this proposition. If this aerobic vibrio is 
harmless, it is because it cannot live in the temperature of the 
body of the animals. Towards 38° already, its motions and its mul¬ 
tiplication are suspended, and once inoculated it disappeared 
under the skin—digested, we might say. 
Scientific novelties often come against prejudices. Well, some 
will say, what of your bacteries affid vibrios ? What are those infi¬ 
nitely small to us? Are they not seen swarming everywhere ? Are 
they not seen in abundance upon the linen of dressings, covering 
even the wounds granulating fast towards cicatrization ? Is there 
any danger ? 
To these I would ask, of what infinitely small do you speak ? 
We have seen that alongside the ipost dangerous vibrios, tliere 
exists very harmless ones, and certainly these last are far from 
being the only microbes free of all virulency. 
Brought by the proof of the cause of the iifhocuity of the
