CENTRAL VETERINARY MEDICAL SOCIETY. 
The usual monthly meeting of this Society was held Thursday, 
January 4th ult., the President, George Pleming, Esq., in the 
chair. 
Pour new Pellows were unanimously elected, viz. Messrs. 
Cheeseman, Mosley, Lawrence, and East. 
Mr. J. Woodger, jun., laid before the meeting a brain with 
two tumours each attached to the choroid plexus, which gave 
rise to a very interesting discussion: several similar cases were 
quoted by Messrs. Pleming, Wragg, and Clark. 
Mr. Burrell introduced a syphon trochar, similar to those at 
the present time used in hospitals, and he advocated the use of 
it. The instrument has attached to it a flexible tube which serves 
to draw off the fluid without allowing the admission of air. The 
latter point was the subject of some discussion, several Pellows 
being of opinion that the admission of air was not so injurious 
as generally supposed. 
The President next produced some navicular bones, which 
gave rise to a very lengthened discussion upon navicularthritis 
and frog pressure. 
Messrs. Cox, P. Mavor, and Burrell, considered that a great 
number of cases were due to rheumatic affections.

Mr. President and Gentlemen. —I can scarcely reconcile 
myself to the position I now have the honour and privilege to 
occupy, because I well know and feel how utterly inadequate are 
my abilities for the duty before me. However, Gentlemen, rather 
than I should be found wanting, to further the interest of this 
Association, I ventured to undertake the duty of preparing this 
Paper, which I trust will be of sufficient interest to produce a 
hearty and friendly discussion. Although I feel cognisant of the 
fact that there are members here present to-night better able to 
treat the subject more practically and scientifically than I am, 
nevertheless my object has been to throw as much light (practi-
