pecting the horse would not need it any longer than a few 
days. 
Despite the original symptoms, and an amnestic report, 
indicating a spasmodic affection of the larynx, I was obliged 
on the following day to change my diagnosis to “ Glottis 
oedema,” owing to the phenomena which developed through 
the night. All went well until the eleventh day, when 1 
plugged the openings of the tube, as I thought sufficiently 
long to produce wheezing if the air passages were not clear; 
removed the canula, cleaned it, etc., but in eight to ten min¬ 
utes after he commenced roaring again. My expectations 
not being realized, I felt obliged to insert another tube, of a 
larger caliber, which served two weeks longer, when the 
horse seemed to be all right, with the exception of the heal¬ 
ing of the wound ; whilst this was going on the horse re¬ 
ceived daily exercise, without showing any deficiency. But 
we were destined to be disappointed, for in the first day’s hard 
work, it was found that his respiration was not yet normal. 
The proposition to send him to pasture for a few months 
met with approval, from whence we receive most satisfactory 
reports. 
The active participation taken by some of our most pro¬ 
gressive surgeons, in the laryngeal operation, “ laryngot- 
omy,” recorded in the American Veterinary Review, leads 
us to believe that diseases of the throat are attracting more 
attention than heretofore. 
Considering these facts, a translation of an article on 
“ Spasmus Glottidis,” by Prof. Anocker, in Koch’s Encyclo¬ 
pedia der Thierheilkunde, will undoubtedly be appreciated. 
It reads as follows : 
Spasm of the glottis, spasmus glottidis, consists in tonic 
contractions of the lateral crico-arytenoid, the inferior and 
superior thyro-arytenoid, and the transverse arytenoid mus¬ 
cles; secondly, also the muscles of the neck. As in asthma, 
the cause has been sought for in the reflex irritation of the 
nerves of the larynx, consequently the spasmodic attacks 
recur at uncertain intervals. As the glottis becomes con¬ 
tracted during glottis spasms, it produces a dyspnoe, attended
