ON THE RE-ABSORPTION OF PUS. 251 
fluid of very bad character runs from most of the buttons that 
have been cauterized. 
—The animal is in a state of extreme emaciation. He 
no longer feeds. Another swelling, with deep fluctuation, an¬ 
nounces a fresh abscess in the very substance of the parotid. The 
animal was destroyed, the consent of the owner being obtained. 
Examination ,—Every lesion characteristic of farcy was found 
in the cellular tissue, the vessels, and the lymphatic ganglions. 
The lungs contained a great quantity of small purulent masses, 
in every point resembling the buttons of subcutaneous farcy. 
Some of these little masses, softer and consequently older than 
the others, had begun to surround themselves with cysts; others, 
the consistence of which was yet caseous, were surrounded by 
hepatized pulmonary tissue. For the most part the smallest of 
them were surrounded by tissue either entirely sound, or simply 
ecchymosed. 
CASE III. 
An entire draught horse, ten years old, was brought to the in¬ 
firmary to be treated for a suppurating wound of the withers. 
History ,—Twelve or fifteen days before, a voluminous cyst ap¬ 
peared on the withers, the consequence of rubbng it. A veteri¬ 
narian, called in a few days afterwards, instead of treating the 
tumour by resolutives, punctured it at once. The wound sup¬ 
purated abundantly, and the skin peeled off for the space of nearly 
a foot from the superior part and right side of the withers. On 
the left side there was a slight engorgement, with a little fluctua¬ 
tion ; but there was no communication between the two abscesses. 
From the 6th of January to the 2d of March various means 
were tried ; but the cicatrization w'as not more advanced than on 
the first day. More than once during that interval the attendants 
thought that the cure would soon be complete, for the fistula dimi¬ 
nished in depth ; the skin appeared to adhere to the parts beneath 
over almost the whole of the withers; the quantity of pus dis¬ 
charged diminished, and it became very thick, and the swelling 
had nearly subsided, when, taking advantage of a moment 
during which he was not watched, the animal rubbed it again : 
every precaution and every care that had been taken was de¬ 
feated, and the evil reappeared worse than ever. 
March i\lh .—On sounding the right fistula anew, it appeared 
that it extended on the left side at least four inches from the 
median plane. A counter overture was made on that spot, and 
a seton was passed through it and carried to the inferior portion 
of the right side. 
Until the F3th of April the horse was alternately better and
