THE EFFICACY OF DEEP CAUTERY LESIONS.

Remarks . — This was a case of pure acute coronitis. The swollen 
fetlock was only the effect of irritation, though it was at first 
considered to be the cause of the lameness. It subsided without any 
treatment, so soon as the cause which produced it was removed. 
I have no doubt that the affection had been brought on from the 
very dry and hot weather, and consequent hardness of the roads and 
heat of the pavement. It is comparatively rare to find so well 
marked a case of acute coronitis, its most frequent form being the 
chronic state. It is also singular, that only the anterior part of the 
coronary body was affected to any extent, the posterior part being 
quite free. I have no doubt that this arose from the greater flexi- 
bility of these parts, mitigating the effects of the concussion. 
UPON THE EFFICACY OF DEEP CAUTERY LESIONS 
AS A THERAPEUTIC AGENT IN BONE-SPAVIN AND OTHER CHRONIC 
LAMENESSES OF HORSES. 
By Mr. James Turner, Regent-street. 
The hock-joint is regarded by horsemen, professional and other- 
wise, as the wearing place of the hinder extremity : most cases of 
lameness of the hind leg of any duration are referrible to this large, 
complex, and important joint. 
Very valuable contributions have lately appeared in The Ve- 
terinarian, in a series of papers upon the subject of bone-spavin, 
from the able pen of my friend, Mr. Percivall. I, for one, have 
perused them with much instruction, and therefore most confidently 
embrace this opportunity of entreating the attention of the veteri- 
nary student to their minutest details. 
I point especially to the student ; because they comprise the 
anatomy, as well as the pathology and therapeutics concerning the 
hock-joint ; but they will amply repay the most busy scientific 
practitioner for his valuable time in their perusal, if followed by 
grave reflection in addition. 
There is much to praise in this work as a whole ; but the July 
paper of this eminent veterinarian on the subject of spavin, touching 
its curability and treatment, I must confess has excited not only 
my surprise, but serious apprehensions for the reputation of the 
great body of operating surgeons throughout the united kingdom. 
Mr. Percivall is deservedly a great authority ; and therefore any 
erroneous opinion which he may promulgate to the world will be
