EXTRACTS FROM EXCHANGES.

than have recourse to any mild form of treatment, it was de¬ 
cided to perform an operation which the professor had already 
tried, and which, in these days of aseptic and antiseptic meas¬ 
ures, could be given good results. The animal being thrown 
and placed on his back as for castration, disinfection of the re¬ 
gion being thoroughly accomplished, the operation was per¬ 
formed on the left side first. The fistulous tract was enlarged^ 
the spermatic cord severed and drawn out b}-’ an assistant, and 
by careful dissection was isolated from the fistulous structure. 
A double ligature of aseptic silk was applied on the cord high 
up, as near the ring as possible, and the part below them was 
amputated. The cavity left was curetted, and the skin closed 
by sutures, except for the passage of a drainage tube. The right 
side was operated upon in the same way. For both, in fact, 
the interference was similar to that often used in cases of scir- 
rhus cord. The dressings consisted in large irrigations and 
washings through the drainage tube of a solution of sublimate, 
I per cent. Operated upon on November 23, the tubes were 
removed on the 27th, and on December 7th the animal was dis¬ 
charged. The cicatrization by first intention had taken place 
in almost the entire extent of the wound. 
Enormous Swelling of the Great Sesamoid Sheath 
OF THE Left Hind Leg. —This unusually interesting case is 
that of an aged horse which presented on the fetlock of his left 
hind leg at the location of windgalls an enlargement as big as 
a man’s head, occupying the external and posterior part of the 
fetlock, extending a little on the inside and running upwards 
to the lower half of the cannon, where it gradually diminished. 
The horse was very lame even in walking. Satisfied that no 
form of treatment, ignipuncture or any other cauterization, 
could be beneficial, as a last resort extirpation of the tumor was 
decided upon. The animal was cast and by two incisions, one 
vertical and one horizontal, the growth was carefully exposed, 
dissected and removed, without accident, except a small opening 
of the synovial bursa of the superficial flexor of the phalanges, 
which was closed by catgut ligatures. Drainage tubes were 
placed on the upper and lower parts of the wound, which was 
closed by strong sutures with silk of Firenza, and a treatment 
established of large irrigations of solutions of corrosive subli¬ 
mate. After the operation the fetlock had assumed its normal 
proportions and the animal standing well on his leg. After a 
few days, to control the motions of the articulation, a light 
bandage of sterilized gauze was applied. The case progressed
