CENTRAL VETERINARY MEDICAL SOCIETY. 
At an ordinary meeting, held at No. 10, Red Lion Square, W.C., on 
Thursday Evening, May 6th, the President in the chair, 
Mr. A. Broad introduced a specimen of hip disease. He was afraid it 
would not present the interest it might have done, as he did not know 
the history of the case, but simply came to hand on the horse being 
slaughtered. He found masses of bone at the hip and on the femur; 
also°a specific deposit in the lumbar region to an enormous degree, 
pieces lying close to it in apposition to the rough surface of the femur ; 
found the os innominatum and acetabulum quite healthy; the pieces were 
very closely kept together. The horse was a mere skeleton when he saw 
the body; it only showed what unsuspected disease might be going on. 
Thought hip disease was looked upon as rare. 
Mr. H. R. Shaw exhibited a piece of a lung taken from a two-year-old 
ox ; it was from an English bullock ; the other parts were all healthy ; 
there was nothing wrong with the liver or intestines ; only one side of the 
lung was disordered, and that at the edges. The animal was slaughtered 
at the market. 
Mr. Banham brought forward a specimen of ulceration of stomach, 
with enlargement of spleen, taken from a retriever dog. The animal 
was brought to him twenty-four hours before death. Found extreme 
growth of the bronchial glands and spleen ; the liver was also affected, 
but the lungs and kidneys were quite healthy ; thought it was leucocy- 
themia or leukaemia—lymphatic growth. It was an extraordinary speci¬ 
men, and, he believed, was rarely found in the lower animals, though 
common in other subjects. Thought the actual cause of death arose from 
ulceration of the stomach and rupture of the vessels. The intestines 
were full of blood. After the animal died found a large pool of blood in 
the room ; believed the growth had but little to do with the cause of 
death. The dog had been vomiting for a fortnight or three weeks 
occasionally. When he saw it, it could not keep anything on its stomach, 
was much emaciated and very weak. He had brought the specimen 
before their notice on account of the growth, as a characteristic case of 
leucocythemia. 
The Secretary had destroyed numbers of dogs, and had made post¬ 
mortems on them and others, but never remembered seeing anything like 
the present specimen. There were generally some traces of the forma¬ 
tion ; did not see how it could be cured. The appearances would never 
be suspected during life ; there might, perhaps, be a slight thickening 
in the chest, but had found it in the back. 
The Chairman believed it to be an ordinary case of gastric irritation; 
it was only the spleen that was enlarged. 
Mr. Banham thought that was all one could diagnose. Could not tell 
the cause the ulceration in the stomach or the actual cause of death; it 
might have been through rupture of some of the vessels. 
Mr. G. Gerrard thought the enlargement of the spleen was simply due 
to the wasting away of the tissues of the body. Bennett discovered 
white corpuscles in the blood, but gave no accounts approaching this. 
They were very easily detected by the microscope. He knew the case of 
a dog that died because it could not pass a small pebble through its 
bowels; it died from excessive vomition. In the present case the en¬ 
largement, pressing upon the intestines, might have diverted the nervous
