and a thick hood over his head and neck. If, for all this, he 
is still blowing and the pulse keeps up, let him continue to 
breathe the cool air,at 40° or 45 Fah. unless he is shaking,then 
let him breathe warmer air,and give him a diffusible stimulant. 
After this, it is frequently the case—say in half an hour— 
that a reaction takes place, and the whole body becomes 
over-heated ; and unless this circumstance be observed, and 
some of the clothing removed, the excitement increases to 
such an extent as to cause serious injury. This may be, and 
in fact frequently is, mistaken for increase of the disease : but it 
is not so, it is simply the result of smothered skin; for, remove 
the hood, also some of the clothing and the bandages, and 
we shall find the pulse and breathing will soon settle down 
again. Sometimes the pulse keeps up to 60 for several days 
when every other unfavorable symptom is gradually disap¬ 
pearing. This you need not be alarmed at, as it is merely 
weakness; the inhalation of cool air, and a little more time 
will set this to rights. 
By scrupulously observing the treatment I have laid down, 
I hesitate not to say that the lives of many horses w r 11 be pre¬ 
served, and their natural term of usefulness, and consequent 
remuneration, prolonged beyond what is now usually the 
case. 
Some one, however, may ask the question, Hov ? can you 
supply your patient with cold air at 45° Fah. in the sultry 
summer months w'hen the atmosphere is at 80' to 90° Fah. ? 
This is one of the things I have yet to comment upon.

TUMOUR ON THE POSTERIOR BORDER OF THE 
SUPERIOR CORNU OF THE OS HYOIDES, 
AND SCIRRHOUS THICKENING AT THE 
BASE OF THE EPIGLOTTIS, INTERFERING 
WITH RESPIRATION. 
By William Shipley, M.R.C.V.S., Yarmouth. 
Dear Sir,—1 have taken the liberty of forwarding to 
you a morbid specimen, consisting of the tongue and larynx 
of a gray mare. You will see that there is a tumour on the 
os hyoides, and ulceration at the anterior part of the base of 
the enielottis.
