spects in tine health. The tumor occupies the maxillary space, 
towards the anterior portion. It is of an elongated form, and 
nearly tills the entire space. It is not adherent to the bone, but 
is surrounded with infiltrated tissue, and somewhat movable. It 
is not painful, the animal making no resistance when it is exam¬ 
ined. It does not seem to interfere with mastication, and ex¬ 
amination by the mouth fails to reveal any interference with that 
cavity. 
It is found by reference to the clinic book of the hospital that 
the horse had once before been brought for examination, but, as 
is shown by the history, was not subjected to treatment, the 
growth being then cpiite small and causing no inconvenience at 
that time. 
On the 5th of May the patient was prepared for operation, an 
ounce of chloral-hydrate being administered, and he was cast on 
his left side. An incision was made on one side of the median 
line, but over nearly the middle of the growth, the entire length 
being about six inches, the skin being carefully dissected over 
the whole tumor, the cellular tissue being separated with the 
handle of the knife and the finger. The tumor was thus enucleated, 
though not without involving the division of some of the muscu¬ 
lar fibres of the anterior appendix of the hyoid bone. The cavity 
was then filled with oakum, saturated with carbolic solution, the 
edges being approximated by trimming, and three sutures were 
applied to keep the parts in place. 
The animal was then permitted to get on his feet, and was 
turned loose in a box stall. He was afterwards tied up, however, 
to prevent him from rubbing his head. 
The next day the parts looked well. The oakum was re¬ 
moved, and a dressing of carbolic solution was prescribed and 
applied several times a day. On the 11th the granulations of the 
edo’es were cauterized with nitrate of silver and chloride of zinc, 
and from that date an ordinary dressing was kept on until the 
14th. when he was discharged and returned to his work. 
When removed the tumor weighed about eight ounces. It 
was somewhat irregular and lobulated in form, but seemed to be 
well defined on its outside surface. On section, it presented the
