of the dog, to retain the head. The percolator' being of glass, 
allows the operator to see how matters progress inside of it. 
The dog usually howls and struggles considerably at first, but 
soon quiets down into an unconscious condition. It is probably 
wise before giving the anaesthetic to have the hostler give the 
dog a short walk out-of-doors, to give her an opportunity to 
empty the rectum and bladder, otherwise she is liable to do so 
while the anaesthetic is being given. The bitch is now hung up 
by the hind legs. 
We have found the following method convenient: Have a 
door about three by six feet, place this on end, leaning from 
you at an angle of about ten degrees. Drive two strong nails 
near the top about two feet apart. Take a cord or piece of tick 
bandage three and a half feet long and make slip knot in each 
end of it. Place the legs through the loops and draw tightly 
around the lower portion of the tibial region. The animal is 
then suspended by placing the cord over the nails mentioned 
above. It will be readily understood that these arrangements 
have been made before the operation began. We have found 
this preferable to having the nails driven into the wall as it 
allows shifting to secure desired light. The operator rinces his 
hands in a baisen of the antiseptic solution. The instruments 
have been placed in a similar vessel of the solution before the 
operation began. We use a two per cent, solution of creoline, 
lysol or thyme-creysol for this purpose. Each has given satis¬ 
faction. The operation is now performed in three steps. 
First Step. —Sponge the abdomen thoroughly from the 
pubes to the sternum with the antiseptic, throw the sponge 
aside. Open the abdomen with the convex bistoury in the 
median line, the lower end of the incision should come to the 
umbilicus. 
SECOND Step. —On examining the cavity the ovaries will 
readily be found. Secure one by the ligament, with the for¬ 
ceps having curved jaws, lock the handles. With the other for¬ 
ceps remove the organ by torsion. Repeat with the other 
ovary. We have never found ligatures necessary.
