ON NEUROTOMY. 
tomy being performed above the fetlock joint. It might not, 
perhaps, be generally known that Mr. Sewell does not advise 
sensation to be entirely cut off, and will in no case perform the 
operation above the fetlock, except for ossification of the lateral 
cartilages. It might be useful to the profession if the history 
of some of these cases were known some eighteen months after 
the operation. 
I have met with two instances of the giving way of the per- 
forans tendon—one, however, was a case of extensive disease 
reaching to the fetlock joint; and the operation was had recourse 
to as a dernier resort , and so far succeeded in enabling the 
animal, otherwise totally useless, to do a twelvemonth’s work. 
The rupture was immediately produced by the mare’s galloping 
about in a field into which she was turned with some other 
horses. On being told that she was again lame, I went to see 
her; and at the distance of a hundred yards I could discern 
sufficient to inform me of the nature of the mischief, so very 
striking is the elevation of the toe and depression of the heel in 
such distressing cases. The other was a case of navicular 
disease and considerable contraction of the feet. The operation 
was first performed below the fetlock without effect (when I say 
without effect, I should mention that the horse went much better 
immediately after the operation, but in a few weeks became as 
lame as ever); the operation was then performed (he being of 
little value) above the joint, and of course he immediately went 
free from pain, and worked for several months in a coach. An 
enlargement, however, gradually took place below the seat of 
operation ; he was in consequence changed away, and in a few 
months afterwards I heard that his foot came off. 
Mr. Sewell performs the operation on the fetlock joint, just 
below the part where a branch nerve is given to the front of 
the foot. He conceives that there will be then sufficient sensa¬ 
tion to prevent the tendon’s rupture, and he finds that, after his 
mode of operating, such deplorable sequelae do not occur. 
In the April number there is a case of glanders, related by Mr. 
Storry, as being cured by fumigating the nostrils with carbonic 
acid gas (accompanied with the administration of internal me¬ 
dicines), on which I would venture a few remarks. I do, how¬ 
ever, not intend to say a word against the practice of fumigation: 
I think, indeed, it is by far the best mode of locally affecting the 
passages of the head, and has been too much lost sight of by 
veterinarians. 
Glanders, I take it, may be either local or constitutional; and, 
if the former, it may be either curable or incurable, according to 
its situation. Now, Mr. Storry says that the horse had a farcy
