the method described, operated on a large number of animals, and 
considered the results encouraging. In those cases which succeeded, 
recovery was not only complete, but lasting. Of four operations performed 
by Siedamgrotzky, one was completely successful, and three rendered the 
horses capable of work. Labat operated on five horses by this method. 
The first two died ; of the remaining three, two completely recovered, and 
one was much improved. 
Plosz operated five times; three cases recovered completely, one 
incompletely, one failed entirely. 
Lanzillotti-Buonsanti used a canula padded with gauze; in one case 
pulmonary gangrene and death occurred, in the other distortion of the 
left side of the epiglottis. 
In six cases Blanchard removed a portion of the cricoid cartilage, and 
claims to have seen improvement. 
Liautard sutured the arytenoid cartilage to the crico-thyroid ligament 
and excised the vocal cord ; four cases are said to have recovered, and 
two to have been improved. 
A large number of cases of operation for roaring will be found 
described in Cadiot and Dollar’s “ Clinical Veterinary Medicine and 
Surgery,” pp. 30 to 34, and pp. 347 to 353.
