GLANDERS *IN ILLINOIS. 
We have' received from Dr. Paaren, State Veterinarian, the 
reports of the proceedings of the Illinois State Board of Health, 
which contain the history of the outbreak of glanders with which 
he had to deal, not without difficulty, in June last; and also the 
various acts amending that already existing, together with the 
official opinion of the Attorney General as tQ the powers and 
duties of the State Veterinarian. We regret that these important 
documents did not reach us in time to allow an earlier publica¬ 
tion, but they will be presented to our readers in our next issue. 
PATHOLOGICAL PHYSIOLOGY. 
UPON THE ATTENUATION OF THE BACTERIDIE OF ANTHRAX 
AND OF ITS GERMS UNDER THE INFLUENCE OF ANTISEP¬ 
TIC SUBSTANCES. 
By M. Chambekland & Roux. 
We have established the fact—in a note presented to the Acad¬ 
emy—that the bacteridie of anthrax is modified in its virulency 
when placed in a medium containing an antiseptic substance, and 
especially phenic acid, or bichromate of potash. We have shown 
that the threads of bacteridie which have been submitted to the 
action of these agents reproduce themselves when in proper mix¬ 
tures, with its diminished virulency, and that it gives their germs, 
which also perpetuate its new qualities. 
In another series of experiments, we have submitted the bac¬ 
teridie thread to the action of the chemical agent in a liquid 
where its reproduction was not possible; we have brought the 
fully formed bacteridie under the action of an antiseptic solution 
in pure water, from which it could not derive any nutritive 
element. 
The bacteridie threads of a drop of virulent anthrax blood, 
placed in phenic water of 1-600, soon die. We have seen, how¬ 
ever, that the bacteridie lives and grows for months in a nutritive 
bouillon containing as much as 1-600 of phenic acid. In a phenic
