NASAL POLYPUS. 
passage of air through the left nostril also. It was extir- 
pated. 
2d. A very large sessile polypus filled the left nasal cavity; 
its pedicle was cut through and burnt; the animal soon 
recovered. 
3d. Two polipiform masses occupied the nasal cavities of a 
three year old mare, and sprung from the septum nasi and 
false nostrils; they were extirpated by the knife. 
In Dieterich’s f Handbuch der Veterinair-Chirurgie,’ at 
page 236, there is the following foot-note : 
“ 1st. In the Museum of the Veterinary School of Berlin, 
exists a horse’s head, No. 629, which has a polypus in the 
right nasal cavity. It quite blocks up the posterior naris, so 
that the animal could scarcely breath. It is fast, and springs 
from the mucous membrane of the right nasal cavity, close 
under the ethmoid, upon the septum nasi. 
“ 2d. In the Museum of the Veterinary School of Hanover : 
“(a) A horse’s larynx, the cricoid cartilage of which is 
ossified ; under the epiglottis is a polypus which was the cause 
of the horse’s death. 
“(b) The septum nasi of a glandered horse, upon the 
surface of which are attached two spherical polypi, the one 
the size of an apple, the smaller one of a walnut.” 
It is with pleasure I here interrupt the monotonous quota- 
tion of published w r ritings to transcribe a case which occurred 
in Mr. Varnell’s practice in America, and which he has very 
kindly penned for me. 
“ About the year 1838, while living in the United States, I 
was requested by a person to examine a chestnut horse, seven 
years old, which he had bought very cheaply on suspicion 
that he was glandered. When I saw the horse he was in fair 
condition, but suffering from a continuous and abundant 
discharge from the off nostril. The parts having been washed 
I proceeded to examine them, and discovered an irregular 
shaped fleshy substance filling up the whole of the nasal 
passage ; it could be reached wdth the end of the finger, 
and the slightest manipulation made it bleed. When an 
appropriate amount of light was made to fall on the 
tumour it was seen to be extremely nodulated on its in- 
ferior surface, and to possess a glutinous appearance. A 
surgeon who was with me, gave it as his opinion that 
it w 7 as a polypus, and at th$ same time he stated that in 
all probability I should find it attached by a peduncle to the 
membrane wdiich covers the septum nasi. Exploration with a 
whalebone probe convinced me that such w^as the case, and 
that the origin of the peduncle w T as several inches from the
