CENTRAL VETERINARY MEDICAL SOCIETY. 
The usual monthly meeting of the above Society was held at 
10,, Red Lion Square, London, on Thursday, May 2nd, 1872; 
the President, George Eleming, Esq., E.R.G.S., in the chair. 
After the reading of the minutes, a ballot took place for the 
election of Professor Tuson as an Honorary Eellow, and Assistant- 
professor Axe as Eellow of the Society. Later in the evening these 
gentlemen were declared to be elected by twenty-one votes. 
The President introduced to the notice of the members a morbid 
specimen of diseased heart on behalf of Mr. Martin, of Rochester, 
who was unavoidably absent. The animal from which the specimen 
had been taken was an aged mare, and the symptoms evinced were— 
extreme distress when moved, an irregular and intermittent pulse, 
the mucous membranes raised by effusion, the veins replete with 
blood, and a dropsical condition of the body. The post-mortem 
examination showed the heart to be almost filled with fibrin; there 
were also deposits on the valves, which were much diseased, 
those on the right side being the most affected; the parieteswere 
thin, and the whole heart was much enlarged. 
Mr. Wragg laid before the meeting a diseased kidney of a 
horse. The animal during life evinced no symptoms of renal 
affection; he had been in the habit of driving the horse himself 
till, being destroyed for an affection of the lungs, a post-mortem 
was made. The kidney was large and softened, and small quan¬ 
tities of pus escaped from its pelvis; it was enlarged to a con¬ 
siderable extent (as also the other, which was not exhibited); 
externally it was whitish, and when opened appeared hypertrophied, 
and to be studded with fatty deposits; more closely examined, 
small abscesses were discovered, but no large ones. 
Mr. A. Mavor showed a portion of the caecum of a horse that 
had died from superpurgation. The attack had come on sud¬ 
denly, the pulse being imperceptible, attended with excessive 
prostration and shivering, continual purging, the faeces becoming 
discoloured from an admixture of blood; the temperature taken 
previous to death stood at 10 Of. After death the rectum and 
caecum were found to be black with effusion, the mucous coats 
only being affected; the stomach was healthy, and its contents 
undergoing the natural process of digestion. There had been no 
symptoms of purpura during life. Of the previous history of the 
horse little was known, save that it was a recent purchase from the 
country, and that the symptoms were sudden in their appearance. 
The President observed that this case bore some resemblance
