VETERINARY SCHOOL AT ALFORT.

otherwise to possess a good constitution, M. Renault, after making 
the owners perfectly aware of the danger of the case, and of the 
operation, attempted and executed the excision of the ganglions 
of the groin. They were more or less reddened and infiltrated ; 
and some of them were filled with pus, a portion of which 
escaped from the ulcerated buttons. A month afterwards, one 
of these horses was perfectly well, and resumed and continues 
his work. The other seemed to be going on well, but unfortu¬ 
nately received a w ound which penetrated into the chest, and of 
which he died. 
Mange. —In pursuing his inquiries into the pathological effect 
of purulent re-absorption, M. Renault felt assured, that in many 
horses and dogs mange, more or less extensive, and almost 
alway obstinate, arose from the cessation of discharge from suppu¬ 
rating wounds of some depth and extent which had been 
inflicted on the animals. 
Surgical Operations. —The great number of operations 
performed in the school during the last year have convinced the 
Professor of the truth and importance of a principle not suflScicntly 
appreciated, namely, the advantage which, in most cases, is de¬ 
rived from free incisions, prolonged, if possible, to the most depen¬ 
dent part of which the wound is capable. Attending to this, the 
Veterinarian will not only operate better, but more quickly and 
easily; while the accumulation of pus in the w'ound wall be pre¬ 
vented, and the cicatrization will be hastened to an extent that 
would scarcely be thought possible. 
Thrombus. —Several very serious cases of thrombus have 
been treated with perfect success. One in particular was accom¬ 
panied by local gangrene, hemorrhage repeated almost every 
minute, arachnitis, and an aflection of the lungs, in which the 
fetor of the breath threatened a speedy termination of the case 
in gangrene. We regret that we have not space for the inser¬ 
tion of this case. 
Carditis. —Some veterinarians of much deserved repute 
have spoken of inflammation of the membrane lining the cavities 
of the heart. This, however, is a morbid lesion accompanying 
various diseases, and particularly maladies of a typhoid cha¬ 
racter. 
A horse was brought to the hospital exhibiting a series of 
symptoms which evidently betrayed an aflection of the heart. On 
opening him, we found all the lesions characteristic of internal 
serous inflammation in yellow membranous productions, soft yet 
well formed, lining a part of the left auricle, and the mitral and 
tricuspid valves. Beneath the serous membrane was a yellow
