divided on the standing animal and the clamp removed. It had 
grown in so tightly that it proved quite a task to get it loose. 
The wound was cleansed thoroughly and healed within two 
weeks. 
This operation brought two more and both were successful. 
On the second one the clamp was taken off after six days, but 
with considerable haemorrhage, necessitating tamponing and 
stitching and followed with extensive swelling. 
The third case was treated like the first; the clamp came off 
after 17 days, when the owner pulled the tie string with some 
force.

Evisceration or Exenteration. —This operation has its 
indications and contra-indications. There are numerous cases 
that will do better by enucleation than by evisceration, especially 
when there is danger of sympathetic ophthalmitis. Nevertheless 
there are cases in which the importance of the operation should 
not be overlooked. The appearance of an animal can be greatly 
improved by the introduction of an artificial eye (prothesis ocuh). 
Although this is not a common procedure in veterinary practice, 
it is one which may at times be of some value to owners of favor¬ 
ite and valuable animals. The indications for evisceration are : 
1. Staphyloma. 
2. Suppurating corneitis. 
3. Suppurating choroiditis. 
4. Accidental wounds. 
5. Opacity of cornea. 
6. Injuries from heat or chemicals. 
1. Staphyloma. —All cases of staphylomata which are com¬ 
plicated by conditions that will favor infection and extension of 
inflammation to the meninges or to the other eye, must be con¬ 
sidered contraindications for the operation; but, such staphy¬ 
lomata as are generally observed in the lower animals, and 
which cannot be successfully treated by other surgical interven¬ 
tion without destroying the eyeball, may be considered favorable 
cases for evisceration. However, if there is danger of infection,
