waU;lied, in case tlie spasm miglit return. In the middle of fo 

 night I was again called, in haste; and this time the breathing 

 seemed, if possible, worse than before, and it was evident that, if 

 no relief were afforded, the animal must soon be suffocated. I 

 accordingly, with some difficulty, owing to his struggles, per- 

 formed tracheotomy. The relief was instantaneous, and he waa 

 •lOon on his legs, and anxious to feed. From this time the trach- 

 eotomy tube was kept in his throat for a week, when, considering 

 that the glottis might have resumed its normal functions, I placed 

 a cork in the orifice of the tube and sent him to work, as an 

 experiment, ordering the cork to be removed if any symptom 

 of suffocation should come on. We, however, foimd that the 

 slightest effort at exertion brought on a fit of bad breathing, and 

 it became evident that he would not work without tlie tube. 

 The horse was accordingly sent to his regular work with the tube 

 in his trachea, and, for three or four months, he did his accus- 

 tomed labor with it in. At the end of that time, however, by 

 an accident, the tube fell out, when he was some miles from 

 home, and the horse coming home tolerably well without it, the 

 horse-keeper neglected to inform me of it for a day or two, and 

 when I saw my patient, the aperture in the muscles of the neck 

 had closed. As the horse now seemed to work well without the 

 tracheotoray tube, it was not reinserted, and from that time to 

 this (more than two years) he had not another attack." 



Should a case of this kind occur, and the consulted party have 

 no tube at hand, he must pass a ligature through each side of 

 the orifice, including a portion of skin and muscles. Each liga- 

 ture is then to be passed over opposite sides of the neck, and tied 

 at the upper part, just tight enough to keep the lips of the 

 wound apart. In this way air is admitted into the wiudf)ipe, 

 and thus the animal is out of dang-er.

Laryngitis (Suppurative and Inflammatory). 



Lar}mgitis signifies inflanmiation of the lining membrane of 

 the larynx. On ap])lying the ear to the region of the throat, th« 

 lociility of the affection is very evident, from the fact that no such 

 embarrassed sound can be elicited in the lower part of the wind- 

 pipe. Hence it must be inferred that the disease is located ia 

 the upper, or superior, passaire of respiration
