when once established it was very evident even at a moderate jog. 
Operated on the 22d of September, cocaine being used locally. 
On exposing the larynx, the left cord was found to be entirely 
motionless, the right one perfectly normal in function, this fact 
leading us to suppose that the case was one of a favorable nature. 
By the 15th of October the wound had entirely healed, leaving 
but a very small cicatrix. Being put to the test under the saddle 
on sharp trot for about a quarter of a mile, she emitted just as 
much of a sound as before the operation. 
Case No. 3 was a bay mare, age 18 years, a dissecting subject, 
not a roarer, but experimented upon so as to see afrerwards what 
changes will take place in the larynx. Oast on the 11th of Sep¬ 
tember, the manipulations being the same as the other two cases. 
Wound had closed completely by the 9th of October. Destroyed 
on the 20th of October. The larynx being examined, disclosed that 
the wound created in removing the cord had healed kindly and 
presented a perfectly normal appearance; the incision through 
the cricoid cartilage was completely closed, but from its inner 
surface exuberant granulations were observed, that projected 
directly into the interior of the larynx, which fact may explain 
why the two preceding cases proved unsatisfactory. 
The above cases although proving failures, flat failures, must 
not lead to final deductions as to the value of the operation. It 
certainly is worthy of a more extended trial, if for no other reason 
than its extreme simplicity and destitution of all danger. 
Case No. 4 was another case of laryngotomy, another fail¬ 
ure. A chestnut gelding, four years of age, roaring upon the least 
exertion, dating from an acute attack of laryngitis in the fall of 
’87. Reluctantly operated upon at the earnest solicitation of the 
owner on the 29th of November, and put to the test on the 14th 
of December, when he was found to be as badly off as ever. 
The above cases, although proving failures, flat failures, must 
not lead to final deductions as to the value of the operation ; it 
certainly is worthy of a more extensive trial, if for no other rea¬ 
son than its extreme simplicity and destitution of all danger. 
Gunther, a German veterinarian, was the first to perform the oper¬ 
ation in 1834, and its lethargic disuse since that time, until re-
