FRACTURE OF THE OS CALCIS. 
By Mr. W. A. Cartwright, Whitchurch. 
_ * 
On the 12th June, 1829, Mr. Stannier, of Ferrybank, sent for 
me to see a cart colt, two months old, that had hurt his hock a 
few days before, by leaping at some rails, and getting his leg 
between them, his body hanging over on the other side. On ex¬ 
amination, I found that there was a simple horizontal fracture of 
the whole of the os calcis about its middle. 
Treatment .—A piece of wood was made in the form of a 
splint, so as to reach from the middle of the tibia to that of the 
metatarsal bone, and which was applied to the front of the leg, 
to keep the hock from having the usual motion, and to relax the 
muscles inserted into the os calcis : underneath this splint a 
charge was applied about the part, and well padded with tow, 
to form a level surface for the splint to rest upon ; the whole was 
bound together with proper adhesive bandages, and he 'was 
ordered to be kept quiet in the stable, but not to be slung. In 
about two months after the hock was fired, and is now perfectly 
well, there only being a little enlargement where union took 
place. 
FRACTURE OF THE HUMERUS IN A COW. 
By the same. 
A five-year-old cow, belonging to Mr. Roberts, of the Brick 
Wall, broke her near humerus on the 21st May, 1829, about 
its middle. The integument was not injured. I bound it up 
with a charge and bandages as well as I could, but did not sling 
her, and she fed very well all the time the bone was uniting, 
which was between two and three months. When united, the 
humerus was not quite straight, being bent a little towards her 
body where the fracture had taken place. Within this last 
month she was taken up to be fed, and is now nearly fat. 
ON CROTON SEED AND ITS FARINA. 
By the same. 
In Mr. PercivalFs excellent u Lectures on the Veterinary 
Art,” he has introduced Mr. Field’s experience on the purga¬ 
tive effect of the farina of the croton seed, and says that five 
grains of it are equal to a drachm of Barbadoes aloes.. I would
