presence of a pathological liquid at the surface or at the depth of a 
wound for a certain time. 
Purulent, or putrid infection may also result from the same 
causes, or mechanism, which we have not to consider at present. 
These gourmy abscesses, developed at once under the influence 
of external violence, in a sub-cutaneous part or at a greater 
depth in the lymphatic ganglions, without being very dangerous 
by themselves, may have fatal terminations, by the situation they 
occupy round articular or splanchnic cavities; by the exhaustion 
that they sometimes produce when the suppuration is very 
abundant; and also by the general infection of the economy. 
For these reasons it was important to demonstrate as well as pos¬ 
sible their ordinary causes.

GANGRENOUS MAMMITIS IN A COW—SEPTIC INFECTION—ANTI¬ 
SEPTIC TREATMENT—RECOVERY. 
By M. Gaignard. 
A cow, which had given birth to a fine calf, was about a week 
later found sick. Her right udder was swollen, painful to the 
touch, and from one of the teats ran a bloody serosity. There 
was anorexia, increased respiration and febrile pulse. Two days 
later the symptoms were more serious and more marked, the milk 
had stopped and rumination had ceased. The mammae whs red, 
hard, swollen and painful, the teats hard and stiff, giving only a 
reddish serosity and a grnmous, thick mass. Notwithstanding 
the treatment of local applications, scarifications, etc., the disease 
kept on progressing. 
The next day fluctuation was manifest, and on opening, about 
a quart of thick serosity, of chocolate color, and mixed with thick 
membranous debris from the galactophore sinuses, was allowed to 
escape. Gangrene was rapidly involving the whole organ.
