peeled and instructive, that we felt ourselves warranted in com¬ 
municating them to the profession, though admitting that our 
experiments were preliminary and quite incomplete. 
Case I. was an adult roadster gelding, vigorous and sound so 
far as known except well marked laryngismus paralyticus, on 
which account he entered the clinic for the removal of the left 
/ 
arytenoid cartilage. After careful dieting he was cast for the 
operation on June 3d. General anaesthesia was omitted and 
cocaine used to produce local insensibility. A tracheotomy tube 
was inserted some twelve inches downwards from the larynx, 
after which the arytenoid cartilage was excised in the ordinary 
manner by the senior author of this paper. The patient fought 
viciously throughout the operation, and the day being warm he 
became very hot and bathed in profuse prespiration. 
The operation completed, the tampon trachea tube was in¬ 
serted and the operation field tamponaded with absorbent cotton 
and iodoform. 
When released, the patient required assistance to regain his 
feet, and was so greatly exhausted that he was placed in slings. 
On. June 4th the tampon and canula were removed, the 
operation field carefully sponged with i-iooo sublimate solution, 
and the horse was permitted to drink a goodly quantity of milk, 
which he apparently relished. From this time until June loth 
the patient seemed bright, drank liquid food with avidity, tem¬ 
perature was normal, and all appeared well except an abundant 
and ever-increasing foetid purulent discharge from the nostrils 
and tracheal openings. 
On June loth he appeared weaker and had fallen down, but 
was quickly assisted to his feet, and the foetor of tracheal dis¬ 
charges still increasing, we injected small quantities of hydro¬ 
gen peroxide into the trachea, which cause the discharge of 
some froth. 
On the nth well-defined suppurative broncho-pneumonia 
was noted, the patient was rapidly failing, and the area of dis¬ 
ease was so great that the intra-tracheal injection of small vol¬ 
umes of antiseptics could promise no benefit. At this juncture
