CANCER IN HORSES. 
session of his present owner for several years, and was used 
for gig or light-cart work. Until recently his health had been 
good. Towards the end of October last, he appeared some- 
what dull, and declined eating anything but corn. He 
continued at work, however, but showed a singular forgetful- 
ness (if such it may be termed) of roads he regularly travelled, 
and was continually apt to turn in the wrong direction. At 
this time he had a dose of purgative medicine, which operated 
freely. 
About the middle of November his near eye became dull, 
and towards the end of the month, as the servant said, “a 
slough ” formed upon it. This w r as dressed with some caustic. 
Nothing further was done for it until the day of his attend- 
ance above mentioned (Dec. 11th). On this occasion he 
reeled much in walking, and could not turn round without 
apparent danger of falling. The cornea of the near eye was 
quite disorganised, and seemed replaced by a thick, vascular, 
fungoid texture, of a dark pink hue. This fungoid growth 
was most abundant at the inner aspect of the cornea, where 
it became continuous in surface with the membrana nicti- 
tans, which presented the same appearances in an aggra- 
vated form. The eyeball was unnaturally prominent. 
Lunar caustic was applied to the diseased surface ; cloths 
constantly wet with cold water were ordered to the same 
parts, and to the entire head. A dose of physic (aloes) was 
also given. 
From the 11th to the 23d the water dressing and caustic 
were continued. The pulse reached 65 and sometimes 70 in 
a minute, but was always soft and compressible. The 
appetite never returned, and the evacuations were of course 
scanty. Great lethargy was almost always present, but the 
horse could mostly be excited to move without much difficulty. 
On the 24th, and during the two subsequent days, he fed a 
little ; the pulse fell to 50, and became firmer in tone. The 
near eye was more protruded ; the exposed and hitherto 
healthy margins of the sclerotica were partially concealed by, 
and involved in the fungoid mass, which projected from the 
affected tarsal and ocular conjunctiva. The right eye also 
looked dull internally, and the cornea was somewhat opaque ; 
these appearances, however, might be due to compression 
from behind, for there was not any sign of structural disease 
in the ball. A copious discharge of sanious fluid came from 
the near nostril ; no ulceration was visible in the Schneiderian 
membrane, and, indeed, the matter was quite unlike that seen 
in glanders. The whole outline of the head seemed unnatu- 
rally round, decidedly swollen in the near temporal region,
