CENTRAL VETERINARY MEDICAL SOCIETY. 
(official report.) 
The monthly meeting of this Association was held on May 4th, 
the President, G. Fleming, Esq., F.R.G.S., M.R.C.V.S., in the 
chair. 
The proceedings of the meeting were commenced by the nomi- 
nation of three candidates for Fellowship, after which the Secretary 
presented, for examination and description, a new form of instrument 
for drenching domestic animals, as invented by Mr. H. Dalziel, of 
Birmingham. Also an improved valve for ventilating stables, after 
his own design. 
The President afterwards submitted the liver of a dog, upon one 
of the lobes of which a large tumour had formed, supposed to be the 
result of injury. In addition to so much alteration of structure of 
the organ, great displacement of others had taken place, as the 
tumour had become so large as to occupy nearly the whole of the 
cavity of the abdomen, which, in consequence, was preternaturally 
large, and gave rise to an impression that much fluid was present. 
Contemporaneous with the enlargement, fits of epileptiform con- 
vulsions commenced, and, at times, succeeded each other rapidly, 
particularly towards the last. They also grew more intense and 
prolonged, and, at length, the animal died during an attack of more 
than ordinary duration and severity. 
Considerable interest was manifested in the morbid specimen, and 
an animated discussion folowed, in which the principal features 
were profitably dwelt upon. 
The President then left the chair, which was delegated to Mr. F. 
J. Mavor, and proceeded to address the meeting on the subject of 
laminitis, with an exposition of a rational mode of treatment, based 
upon observations of the morbid changes which the structures that 
are involved, necessarily undergo in the disease. 
Mr. Fleming said he felt some hesitation in introducing the 
subject, inasmuch, by the title which had been given to it, more 
might be expected than he was prepared to advance. The ex- 
planation was due from him, in order to avoid confusion, that his 
remarks would be confined — not to the acute, but to sub-acute form 
of laminitis. He, however, felt that his hesitation was somewhat 
removed by the presence of Mr. Broad (of Bath), who had raised 
himself to the standard of an authority on the question, by the 
amount of investigation and promulgation of facts he had made in 
connexion with it. He had to admit his experience of the malady is 
much more limited now, than formerly. It is rarely witnessed 
among the horses of military regiments, and army veterinary sur- 
geons see but little of the diseases of hard-worked horses, and his 
position as one is no exception to the rule. His observations were 
principally confined to laminitis as seen among the animals rapidly 
driven, and ridden over the streets and hard roads, among which
