altogether aerobic and anerobic. By applying this method, by 
associating it with others already known, sometimes taking ad¬ 
vantage of good opportunities, as are sometimes met in long 
researches, we have found that the atmosphere and water, those 
immense reservoirs where all microscopic remains of what lived 
are gathered, contain numerous species of aerobics and anerobics. 
Without entering in the details of our observations, we may say 
in a general way, that the inoculation of these organisms often 
bring on fatal disorders, which even seem to constitute diseases as 
new by the specificity of their actions, as by the nature of the 
inoculated organisms. For instance, the septicoemia of which we 
spoke a moment ago, is not the 3nly one. Air and water con¬ 
tains the germs of a vibrio a little bigger in diameter than the 
septic vibrio, more rigid, less flexuous and with slower motions. 
We will describe its effects in another communication. 
The following experiments show again another method of 
separation of microscopic germs. In few points it resembles the 
one already spoken off. 
Let us take a piece of meat of stated weight; say the leg of a 
large mutton, and after singeing it rapidly over its whole surface, 
let us introduce in the thickness of the tissues the blade of a bis- 
touri also singed ; in the opening thus made, drop a few drops of 
common water and insert over it a little ball of wadding which has 
been exposed to a current of air from the street; then cover the leg 
of mutton with a large glass cover. Again renew the same experi¬ 
ment with another leg of mutton also singed, and some drops 
of water throughly deprived of living germs by being warmed to 
119° to 121°. 
If one considers that the muscular tissue absorbes oxygen 
easily in throwing a volume about equal of carbonic acid, one will 
easily understand that our drops of water may be considered as 
having been soon protected from atmospheric air, in presence of 
an element of cultivation, favorable to the development of some 
germs. Besides, it is easy to fill up the glass globe which covers 
the leg of mutton with pure carbonic acid gas. 
Here is the result: after one or at the utmost two days, with a 
temperature of 39° to 40° the gigot with the pure water shows no
