of neurotomy be afterwards passed as sound ? Most certainly 
not. There is altered, impaired structure; there is impaired ac- 
tion ; and there is the possibility of the return of lameness at 
some indefinite period. Let him be ever so free from lameness, 
he has been diseased — he possibly is diseased now ; but, the pain 
which usually accompanies the disease being removed, there are 
no means by which it can be indicated. I operated on a horse 
five years ago ; he continued sound until within the last six 
months, and he has since that time lost one hoof. Generally 
speaking, the good effect of the operation, if well performed, may 
last during life ; but who will guarantee that it was well per- 
formed, or that the horse shall not suffer from those accidents 
to which by the very act of neurotomy he is peculiarly exposed, 
viz. the bruising and battering his feet until inflammation is 
produced, or he cuts his feet to pieces with flint and glass ? The 
horse that has undergone the operation of neurotomy is, ever 
afterwards, unsound. 
A CASE OF ANEURISM OF THE ANTERIOR 
MESENTERIC ARTERY. 
By Mr. H. Daws, London. 
An aged brown gelding, the property of His Grace the Duke 
of Beaufort, was received into the hospital on the 19th of April, 
1836, at 7 a.m., for compound fracture of the bones of the face. 
The nasal, superior and anterior maxillary bones were the prin- 
cipal ones affected; and the air rushed through more than one 
of the openings. The injury was occasioned by his running 
away and coming in contact with an iron railing. 
A considerable hemorrhage took place from the nostrils, and 
the shock to the system was very great. The depressed portions 
of the bone were elevated ; the detached pieces removed ; and 
the external wounds closed by sutures. Aperient medicine was 
administered, and quietude strictly enforced. Febrile symptoms 
exhibiting themselves with the returning re-action, he was bled 
to syncope in the evening. Fomentations, evaporating lotions, 
&c., were applied constantly to the injured parts, which, in a 
few days, took on a healthy action. Exfoliation shortly followed, 
and the wounds cicatrized, leaving a very slight scar, and a little 
disfiguration of the countenance. 
On the 15th of May he was suddenly seized with the follow- 
ing symptoms, about 6 p.m. : — increase of respiration — restless- 
ness-profuse perspiration— distention of the abdomen — frequent
