NASAL POLYPUS. 
acquainted with the various modes of extirpating such 
tumours.* 
Continental veterinary authors speak more or lessin 
general terms about polypus, either copying the ancientsor 
drawing from works on human medicine, or some of them 
from their own very limited observation. Comparatively, 
seldom have cases been recorded in journals or elsewhere, so 
that it would be difficult, not to say impossible, to write a 
complete monograph on nasal polypus. 
English writers treat the subject with little erudition, 
indeed, most of them do not even mention the term poly- 
pus. White, Blaine, Field in his ‘ Records/ and even 
Mayhew in his new edition of Blaine’s work are of this 
number. Youatt, in his work on cattle, says, “This is a 
rare disease in the horse, and still rarer in the ox. We have 
only one case of it, and that might have been said to be 
more polypus of the pharynx than of the nasal cavity, 
had not its pedicle been traced into that cavity, and seem- 
ingly attached to the upper part of the inferior turbinated 
bone.” He goes on to relate a very interesting case of 
polypus in the nose of a cow. In his work on the dog, 
Mr. Youatt speaks in more general terms, though to mfy 
mind not so satisfactorily ; he makes a curious confusion of 
matter by saying, “ The polypi of the nasal and of the anal 
cavities, often show themselves under the form of rounded 
bodies, projecting from the nose or anus, &c.” 
As a proof of how little this interesting subject has been 
considered, I transcribe Mr. Percivall’s words from his 
6 Hippopathology.’ “ Polypus is the name given to an 
excrescence or tumour growing from a mucous membrane 
by a narrow part or neck, called its pedicle. It is a very 
rare occurrence in horses. Never having had a case myself, 
I have nothing of my own to offer on the subject, A very good 
article appeared in the ‘Veterinarian’ for 1834, under the 
signature T., from "which I extract the greater part of 
what follows.” This chapter of Mr. Percivall’s is based on the 
histories of five cases; the first, by Gohier, occurred in the 
left nostril of a horse; it was situated very high up, and 
was removed in an attempt to draw tight the slip knot 
of a ligature round its neck. From Chabert’s ‘Veterinary 
Instructions’ the second is borrowed, which occurred in 
a trooper condemned as giandered by a serjeant farrier ; a 
polypus was afterwards discovered, and M. Tears surgeon to 
the regiment, who “ cast the horse, slit up the nostril, when
