FOREIGN BODY IN THE FETLOCK. 
A roan gelding, purchased six months ago by a livery stable 
keeper, was noticed at the time to have a thickening on the out¬ 
side of the near hind fetlock, but, as the animal was not lame, it 
passed unnoticed until a few days ago, when, apparently increas¬ 
ing, the animal was sent to us for advice and treatment. An abscess 
was in the process of formation at the seat of the induration, and 
hot poultices were applied. This treatment was carried out, and 
when the case was next under observation the abscess had ulcer¬ 
ated through—the discharge was thin and peculiar to diseased 
bone. Introducing a probe, a foreign body was detected, which 
at first was thought to be a detached piece of bone. With¬ 
drawing it with a pair of forceps, it proved to be a piece of a 
large nail, an inch long ; the after treatment consisted merely in 
keeping the parts clean. An interesting fact in this case is, that 
for six months, although used for hacking work, the animal had 
never been noticed to take a lame step. 
USE OF PEPSINE. 
In several cases when no food would be touched by patients, 
the administration of pepsine in half ounce doses twice a day 
has been followed by speedy return of appetite, when other reme¬ 
dies have failed. The greatest objection to its use is that the 
pure article is very difficult to obtain. In a case of hydro thorax 
following pleurisy, its effect was wonderful; the patient had 
eaten nothing for several days. After several doses of pepsine, 
the appetite returned, and convalescence took place. At the 
time when it was given the animal was almost in a state of 
marasmus. 
INTUSSUSCEPTION IN A MONKEY. 
A large male Arabian monkey (Cynocephalus hamadryas) 
was lately seen at Central Park; he had appeared unwell for a 
few days, refusing his food; he was lying crouched up in his
