NASAL POLYPUS.

he not only found it completely filled with polypus, and the 
septum narium bulging into the other division of the cavity ; 
but, from long continued inflammation and pressure, it 
adhered to the membrane of the nose in so many points, and 
so extensively, that it was impossible to get round it or 
move it. He contrived, at length, to pass a crucial liga- 
ture around it, and it was torn out by main force. Four 
considerable portions of the turbinated bones were brought 
away with it. The hemorrhage was excessive, &c.” ee Cha- 
bert, in a case which he had himself, of very large polypus, 
was obliged to make a hole in the frontal bone, which he 
contrived to cover afterwards with a leather shield, attached 
to the front of both bridle and head collar. For a long while 
after recovery the horse ran in a cab.” Rigot relates the 
fourth case, in which the tumour was removed by the knife 
and cautery ; and the fifth, if referred to, will be found to have 
some identity with the case related by Mr. Dickinson. 
D’Arboval, who was well versed in the veterinary lite- 
rature of his country, compiles his article with nearly the 
same cases as Mr. Percivall. There is an additional one by 
Icart, from the volume for 1794 of the ‘ Instructions Vete- 
rinaires ; it is extremely interesting, from the size of the 
tumour and the difficulty of extirpating it ; the knife and 
evulsion were both used. Two others named by Gohier, are 
the only ones I know of in the dog. One of these animals 
was destroyed, and on opening his head, several polypi were 
found near the ethmoid bone, which almost entirely oblite- 
rated the nasal cavities. They were of a whitish colour and 
weighed two ounces, an equal number were existing in the 
two cavities of the nose. In the other dog, it had seem- 
ingly been easy to determine their existence, from the 
impediment to the respiration, and by probing. They were 
got rid of by the continued use of powerful doses of 
arsenic. Notwithstanding our great respect for Gohier’s 
opinion, I should be inclined to doubt his assertions on a point 
like this. Had the dog polypi ? Would arsenic have caused 
their absorption? The answer to the first query, is doubtful : 
to the second, I should reply in the negative. 
In Hering’s ‘Repertorium der Thierheilkunde,’ for 1844, 
at page 355 , I find cited ce three observations of Professor 
Delwart, of whistling and impediment to breathing, through 
morbid productions in the nasal cavities. 
1st. A two year old colt was so affected in his breathing as 
to threaten suffocation on the least exertion. The right nasal 
cavity was found completely plugged by an enormous polypus, 
which pressed against the septum nasi, and impeded the
