CENTRAL VETERINARY MEDICAL SOCIETY. 
The ordinary meeting of this Society was held at 10, Red Lion 
Square, on Thursday, February 6th, the President, P. J. Mavor, 
Esq., in the chair. 
At the commencement of the meeting an animated discussion 
took place on “ Osteo-Porosis," a subject which had been intro¬ 
duced and partly considered at the previous meeting. The chief 
points incidental to the affection which were touched upon had 
reference to the enlarging of the joints, supposed deficiency of 
the earthy salts in the bones, and the character of the herbage 
and soil in those districts where the affection exists. Many 
questions being raised on these and other points, which the report 
on the affection which had been received from Melbourne scarcely 
alluded to, a committee was appointed to prepare a series of 
questions on the subject, and forward them to Mr. Mitchell for 
his reply thereto. 
Mr. Fleming introduced a method of roughing shoes, as shown 
to him by Count Pratasoff. It consisted in square holes being 
punched in the shoe to receive a cube of steel, the projecting face 
being drawn out and sharpened like an ordinary stud. These 
studs were fixed by being simply tapped with a hammer, the 
weight of the horse's body being sufficient to retain them in situ 
when once properly fixed. Mr. Fleming had seen them kept in 
for three weeks without difficulty. They were as easily removed 
from the shoe as they were fixed, by tapping them with a 
hammer upon their sides. 
The President said that his late father had adopted a similar 
method, and also himself up to the present day, the only difference 
being in the form of the stud, the shank of which was made to 
curve over the upper surface of the shoe. 
Mr. Martin (Rochester) laid before the meeting a portion of a 
bladder of an aged grey horse, which during life was subject to 
a frequent slight haemorrhage from the penis. He had cast, the 
horse and injected an astringent mixture into the bladder, which 
checked the flow for a few days, but, fearing to cast him again, 
and neither astringents nor tonics having any beneficial effect, the 
horse was destroyed. The post-mortem examination disclosed an 
ulcerated condition of a portion of mucous membrane of the 
bladder. Mr. Martin next desired to learn the opinion of the 
fellows on the adoption of Mr. Broad's system of treating 
laminitis, as he was frequently called upon to attend cases of the 
disease. He was anxious to adopt efficient remedies, and had
