422 OSSEOUS TUMOUR SUCCESSFULLY REMOVED 
in the minds of many of your readers as to the profundity and 
solidity of my physiological knowledge; but the subject em¬ 
braces one of the most important points in the physiology of 
ruminating animals, viz., whether the entire functions of the 
paunch and manifolds are by their muscular structure for the 
sole purpose of regurgitating and breaking down the food into a 
more pulpy state, in order that, when it arrives at the abomasum 
and intestines, it may be in a fitter state to be operated upon by 
them. The stake is great, and as such I hazard it; knowing 
full well, that no man is afraid of the results of an operation 
when the knife is in the hands of a scientific and humane man. 
A CASE OF OSSEOUS TUMOUR SUCCESSFULLY 
REMOVED FROM THE NOSTRIL OF A HORSE. 
Hj/ Mr. Boycott, V.S., Devonport. 
The subject was a thorough-bred grey horse, four years old, 
the property of Charles Trelawny, Esq. of Plymouth. He had 
been in training; but in consequence of his respiration becoming 
very laborious in fast work, he was sent home, under the impres¬ 
sion of being a confirmed roarer. Shortly afterwards he was 
turned to grass, and while there the groom observed (on the 24th 
July, 1832) a copious discharge from the near nostril; when he 
had him brought in, and on looking up the nostril he observed 
(to use his own words) a large fleshy substance, situated very 
high up; and, in consequence of which, I was requested to ex¬ 
amine the nostril, where I found a considerable growth, which, 
from situation and appearance, I considered to be a nasal poly¬ 
pus. 
From this period up to the 14th of February, the tumour con¬ 
tinued enlarging, producing increased difficulty of breathing and 
deformity. The horse was then sent to my stables ; and having 
had him throwni for the purpose of a more minute examination, 
instead of finding a polypus, 1 found an osseous tumour, which 
not only filled up the entire cavity of the near nostril, but had 
considerably encroached on the off nostril, by pressing the sep¬ 
tum out of its situation in that direction. On an accurate 
investigation of its connexions and situation, I considered the 
tumour to be a morbid growth of the superior turbinated bone. 
It was, at once, evident that the entire removal of the morbid 
substance was the only means which could be devised as,a reme¬ 
dy ; and although I was very sensible of all the difficulties and 
dangers attending such an operation, yet as it was the oidy
