living organisms. This mode of inoculation has not allowed us 
yet to produce abscess in the viscera. But, as well as in injecting 
directly in the blood inert bodies, one may stimulate the formation 
of metastatic abscesses, as well is it easy to obtain similar abs¬ 
cesses either by the living or dead microbe, by injecting them 
into the jugular vein. 
In tins case the lungs, and principally the liver are filled in 
twenty-four hours with large numbers of metastatic abscesses in 
all stages of developement, from the simple inflammatory spot to 
the smallest white pustule filled with pus; but in the point of view 
of cure, that is the disparition of the abscesses, the facts are dif¬ 
ferent in the two modes of inoculation. Often the animal inocu¬ 
lated with the living microbe, dies rapidly, and any portion of the 
liver and lungs sown in an inert liquid, will reproduce the micro¬ 
be. If the sequelae of the inoculation is not fatal, the disappear¬ 
ance of the abscesses and of the microbe in the viscera is slower 
than in the case of the animal inoculated with the dead microbe 
But we must from the preceding experiments remember that 
the pus, loaded with microscopic living beings, whose life may go on 
in the animal economy, brings on greater disorders and more dif¬ 
ficult resorption than what we understand generally by pure pus. 
We have given in the proof of a prevalent infection localized 
in viscera, and produced by foreign bodies or by pus entirely free 
from living organisms, a queer coincidence. A foreign body 
brings on suppuration; the globules of pus have the same power. 
Metaphorically speaking we may say : pus engenders pus. 
If I had time, I would go on and describe the resorption of 
metastatic abscesses. It is a phenomena curious to follow in its 
details, and in which, what is most interesting to observe, is the 
facility with which nature rids itself of the prevalent collections 
which are sometimes so numerous in all the lobes of the liver. 
There is another part of our studies which I would like to 
present to the Academy—that is, the formation proper of the 
pus. But here we arrive at results so contrary to those admitted 
in scientific circles, and it is so difficult to come to a conclusion in 
K 
these very delicate researches, that I may postpone this demon¬ 
stration to another time, For us, actually, the red corpuscles of
