With the recent mode of operation perhaps the results will be 
still better. Good results for the horses, no doubt excellent and 
satisfactory to Prof. Hobday, and of great honor to our esteemed 
friend Williams. 
But there are still some points which demand to be carefully 
considered and among the veterinarians who have performed the 
operation in England and given the profession the benefit of their 
experience and of their observation, Prof. J. J. O’Connor, of the 
Dublin Veterinary College, occupies a first rank. In a recent 
article in the Veterinary Record, he relates one case which sug¬ 
gested to him an addition in the modus operandi of the operation 
and which came to his mind by the observation of a special case. 
Calling first the attention to the fact that on opening the larynx 
of a living or dead animal which has been operated for roaring, 
one will observe the deformity caused by the left arytenoid car¬ 
tilage projecting towards the lumen of the larynx, although the 
laryngeal ventricles have been completely obliterated. And again, 
that he will also notice that this arytenoid is quite movable and 
may yet vibrate and create a noise, perhaps not so strong, but still 
similar to that in the case of a roarer not operated upon. Prof. 
O’Connor relates that a hunter was brought to him for the roar¬ 
ing operation. The * hunter was recognized as one which had 
been operated already two years previous. The skin being shaved, 
showed the cicatrix. The larynx was open, both ventricles were 
found obliterated, but the left arytenoid was movable and de¬ 
cidedly interfering with the lumen of the larynx and of course 
with the respiration. To remedy this, the professor suggests: 
“ In addition to the stripping of the ventricle, to remove a strip 
of mucous membrane from the outer lateral aspect of the aryte¬ 
noid, thus making a wound which in cicatrizing will draw the 
arytenoid away from the median line and fix it to the thyroid, 
thus making it less movable and preventing its coming in the way 
of the inspired air.” Horses operated which would seem to have 
a poor or a bad result might be improved by the proper applica¬ 
tion of this suggestion.
