enced instantaneous relief from suffocation, and all dange: from 
the saine seemed to have immediately passed away. The tube 
was now introduced and secured around the neck in the usual 
manuer, after which the patient received an aloetic enema, and 
hac a strong counter-irritant applied to the submaxillary apace 
and throat, after which the fauces were swabbed with a weak 
solution of alum, by means of sponge secured to a piece of wnale 
bone. On examining the “swab,” a sort of lymphy or albumin 
ous concretion adhered to it; the mucous membrane of the laryna 
was either injected or edematous. The pharynx was not involved, 
as the animal, shortly after the operation, drank two quarts of 
water, containing two drachms of nitrate potassa. 
The tube remained within the trachea for a period of five days, 
during which time very little occurred worth recording, except 
that one night pneumatosis (distension of the cellular membrane 
with air) appeared, which yielded to a dose of hyposulphite of 
soda and an outward application of liquor ammonia acetatis; and, 
also, on the fifth day, a submaxillary tumor was punctured, which 
discharged freely. At the end of the above period, it was ascer- 
tained, by holding a lighted lamp to the nostrils, at the same time 
stepping up the orifice in the instrument, that the animal breathed 
through the usual channel. Then the instrument was removed, 
the parts cleansed, and secured together by suture. The wounds 
healed by the usual process, and, at the end of three weeks, the 
animal was disposed of, and went to work. 
The operation of tracheotomy, formidable as it may appear to 
some, is unattended with danger; yet, like every other process of 
surgery or medicine, is only calculated to relieve certain states 
peculiarly adapted to the remedy. or example, the operation is 
admissible in cases of nasal obstruction, from the preserce of nasal 
polypus or other causes; spasm of the larynx, threatening suffo- 
cation; suppurative laryngitis, when the animal is in great dis- 
tress for “breath ;” and in case of any foreign body occupying the 
larynx, which precludes the possibility of continuing the process 
of respiration. On the other hand, the operation is worse than 
useless in cases of lung difficulty, bronchial obstruction, or when 
obstruction occurs within the trachea posterior to the usual] point 
velected fcr the operation.
