OPEN JOINTS-ANOTHER TREATMENT.

twice a day, which, with what grass she could get, consti¬ 
tuted her rations till the fifteenth of last June, when she gave 
birth to a healthy, well-developed horse colt, which com¬ 
menced thriving better than the average foal under the cir¬ 
cumstances ; the mother doing fairly well with her feed, in¬ 
creased with the different kinds of easily digestible food; but 
the injury still seemed painful, and she still refused to put 
much weight on the injured leg. On the tenth of August 
two more abscesses were noticed forming on the outside of 
the leg, one opposite the joint and the other five inches above 
the joint; it was then evidently a hopeless case, but the 
owner now wished us to do the best we could for her until her 
colt was old enough to wean. So the abscesses were opened 
and the pus allowed to escape. Cleansing them daily with 
carbolic acid solution one to twenty, the lower one healed up 
nicely, but the upper one was slow to heal. So on the 18th 
of September, the colt being old enough to wean, the mare was 
destioyed, the leg amputated above the injury, and the soft 
parts removed. Found the bony parts considerably enlarged 
and of a porous nature, with almost complete anchylosis of the 
entire hock except very limited action in the tibio-tarsal ar¬ 
ticulation. The diseased bone resembles Fig. IV., Plate II., 
in Williams’ Surgery, sixth edition. 
Another case, that came under our treatment July 19th, 
was a medium sized black mare that had been kicked three 
days previous on the same leg and in the same place as the 
preceding case, the opening being straight into the joint and 
the synovial fluid escaping as fast as it formed. We gave the 
opening an injection of an alcoholic saturated solution of 
bi. chlo. of mer, and applied a canth. blister. On the nth the 
owner brought her back to the hospital, and left her for 
us to do the best we could for her; so we commenced 
the peroxide of hydrogen treatment, giving the opening an 
injection twice daily of one to five solution in aqua distillata. 
The constitutional disturbances noted in this case were about 
the same as in the preceding case, but this case not being so 
heavy and not with foal could get up and down at will, the 
discharge from the joint at no time being unhealthy since we 
began the use of peroxide of hydrogen solution. But ten
