The result was a fracture of the left half of the body of the 
premaxillary, carrying with it three incisor teeth. After a good 
deal of manipulation, the bone was pushed back into position, 
and all the incisors held in place by stout copper wire, twisted 
firmly with a pair of pliers, the ends being further twisted 
around the left tusk ; the animal was kept on soft diet only for 
a week. After that hay was allowed and in four or five weeks 
recovery was complete.—(. Ibid .) 
Barium Chroride [By Mr. J. J. Me Carry] .—These are 
the results obtained by the use of barium chloride in experi¬ 
ments established to test the value of Dieckerhoff’s discovery. 
In all the observations gathered of the intravenous injection of 
a solution of the chloride, it appears that its actions upon the 
bowels were followed with the same results, viz., evacuation 
from the bowels of more or less faecal masses, with colicky 
manifestations. The last case is one of a mare which was 
suffering with colic, and to which, on account of her being 
pregnant, had only received the ordinary form of treatment of 
colic. Failing to relieve her with them, the author gave her 
at last an injection of 15 grains of chloride in 5 c.c. of water, 
into the jugular, and obtained relief in less than an hour.—

Hypertrophy of the Prostate Grand [By Mr. J. A. 
Bunn]. Though this affection has been observed frequently in 
dogs, it has not been in horses. The author has, however, 
reported one case already in an aged gelding. This time, his 
second case, though lost sight of, is interesting. There was no 
previous history to be obtained, but the present owner said 
he was suffering with difficulty in urinating, which was kept 
dribbling away from him for a considerable period, alternating 
with a regular gush of fluid. A calculus was suspected, but on 
attempting catheterization, the instrument was stopped in the 
prostatic urethra, and no reasonable amount of force could 
get it. further. Rectal examination showed hypertrophy of 
the middle lobe of the gland, which was greatly enlarged. 
Although carefully searched for, no trace of a calculus could be 
discovered in the bladder, which was empty.— (Ibid.) 
A Wandering Tooth [By J. Paton and J. Dunlop].—In 
the Veterinary Record , the authors report another instance of 
the possible growth of a tooth outside of the walls of the buccal 
cavity, outside of the maxillary bones. This case was in a year¬ 
ling which presented a large abscess in the temporal region in 
front of the left ear close to the scutiform cartilage. The abscess
