enced instantaneous relief from suffocation, and all dangei from 

 the same seemed to have immediately passed away. The tube 

 was now introduced and secured around the neck in the usual 

 manner, after which the patient received an aloetic enema, and 

 had a strong counter-irritant applied to the submaxillary space 

 and throat, after which the fauces w^ere swabbed with a weak 

 solution of alum, by means of sponge secured to a piece of whale* 

 bone. On examining the " swab," a sort of lymphy or albumin- 

 ous concretion adhered to it ; the mucous membrane of ths larynx 

 was either injected or oedematous. The pharynx was not involved, 

 as the animal, shortly after the operatioD, drank two quarts of 

 water, containing two drachms of nitrate potassa. 



The tube remained within the trachea for a period of five day(3, 

 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 ol liquor ammonia acetatis ; and, 

 also, on the fi flh 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 

 stopi^ing 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 opers'^ion of tracheotomy, formidable as it may appear to 

 some. Is unattended with danger; yet, like every other process of 

 8arger\' or ni'^dicine, is only calculated to relieve certain states 

 peculiarly adapted to the remedy. For example, the operation is 

 admissible in cases of nasal obstruction, from the preser.ee of nasal 

 polypus or other causes; spasm of the larynx, threatening suffo- 

 3ation; suppurative laryngitis, when the animal is in great dw- 

 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 traohea posterior to the usual point 

 selected fcr the operation.
