566 VETERINARY SURGICAL THERAPEUTICS. 
to have obtained good results with puncture and the injection of subli~ 
mate corrosive 1 p. 1000 followed by a blister. 
Laffitte in 1886 has said much in favor of a mixture equal parts of 
solutions of ergotine and muriate of morphia. His Observation I relates. 
to a bull which had a large thoroughpin which had resisted blistering ;. 
the injection made, the wound was closed with a stitch, a compressive: 
bandage was applied on the joint ; a month later, recovery was complete.. 
A heifer and a mare were cured by the same method. 
The “baring of the veins” has been advised. 
-—-a fantastic operation consisting in ligating- 
the vein: 1st, below the bony projection where: 
spavin grows; 2d,on the inside of the leg, im-- 
mediately below the small venous branch coming- 
from the anterior tibial muscles. When both. 
ligatures are applied the vessel is open in its. 
whole length between them. A quite abundant. 
hemorrhage takes place, which when it stops- 
indicates the end of the operation, Slight pres- 
sure and tepid lotions on the joint continue the: 
treatment. 
This fantastic operation is said to have been. 
successful in colts. But it must be remembered 
that with them thoroughpins disappear as the 
animal gets old. If the treatment has any effect: 
it must be only by the local irritation it produces. 
Gloag has treated hydarthrosis of the hock by- 
acupuncture: two seatings, five days apart; the- 
last followed by an application of tincture of 
iodine and a compressive bandage. 
Puncture followed by lines or penetrating- 
pointed firing is the select mode of treatment.

sis of the fetlock. Articular Windgalls. 
The articular synovial of the fetlock is strongly protected in front and’ 
on its lateral faces. Its hydarthrosis is accused by two dilatations, sit~ 
uated above the sesamoids, between the cannon bone and the suspen-- 
sory ligament; one on the inside, the other on the outside. These- 
tumors, whose dimensions are rarely larger than that of a large nut, are- 
hard when the leg is at rest, soft and fluctuating when it is raised. With. 
profuse dropsy there is also in.the pastern, along the middle and super-
