MEMOIRS OF A VETERINARY SURGEON.

purpose it is uncalled for, and I do not profess to know 
exactly how to draw the line of demarcation, as to where 
catarrh ends and nasal gleet begins, or where nasal gleet ends 
and glanders begins. I look upon them as one and the same 
disease, differing only in degree. It will be requisite, 
therefore, for me to clear away many considerations which 
would tend only to complicate and confuse, and this being 
done, the writer and the reader will the better understand 
each other. 
Fungous growths, injuries, and diseased teeth, I consider 
artificial causes of nasal gleet ; all other causes I consider 
natural causes. 
ARTIFICIAL CAUSES OF NASAL GLEET. 
There are many cases of nasal gleet which prove very 
troublesome and protracted; they have, however, charac- 
teristics which, if the case be attentively watched by the 
observant practitioner, will satisfy him as to the true seat and 
nature of the disease. There is an absence of tumified glands ; 
the general health does not participate, unless mastication is 
interfered with, w 7 hen the patient will necessarily fall away in 
condition. If it arises from a fungous growth, or diseased facial 
bones, it is painful to witness the degree of annoyance expe- 
rienced by the animal. Sometimes he has a fit of snorting, 
which is continued for some time, when he will toss his head 
up frequently and impatiently, then rub his face against any- 
thing he can get at, always on one side ; the discharge also is 
always from that side, and it is similar in character to other 
nasal discharges, only at times blood is observed to escape along 
with it, and it is always offensive. If there be a polypus, and 
it has existed for any length of time, it w 7 ill acquire propor- 
tions which will interfere with the free ingress and egress of 
the air, and a snuffling or w^heezing noise may be heard in 
the nostril. Should it exist high up, trephining and its 
extirpation constitute the only means of cure. If injured and 
diseased bone be the cause, it is not unfrequently the case 
that the exact spot may be indicated by its tenderness, or an 
indentation maybe made from a softening of the bone at that 
particular place. In such cases, the first treatment, if it has 
existed long, should consist in the application of a blister 
over the part, and this to be repeated, at the same time 
placing the animal under a course of tonic medicines. Should 
this prove ineffectual, then trephining must be resorted to, 
since it may be that the internal plate of bone may be 
bulged inw 7 ardly, and splinters of bone project, which
