REPORTS OF CASES.

sistants ready, I wished to finish without trying - any other solu¬ 
tion of cocaine, so I gave a ball of hydrate of chloral 3 vi; cast 
her, operated above the coronary band by making five incisions 
from the band to the top of the cartilage, and then dissected the 
tissues from the cartilage from one opening to the other. With 
a pair of forceps and a small farrier knife, the cartilage was 
removed. This operation was a success and easily treated. 
The third case was a large black mare about 16 hands high, 
weight about 1200 pounds, a pacer; she was tracked last year 
( 1 893); went lame, supposed to be due to striking her knee; 
she was rested and booted and tried again, and not being im¬ 
proved, she was turned out. Last fall she was brought in and 
the owner came and told me how she acted. Later on he 
brought her for me to see. I told him she was suffering from 
sidebone and then prescribed treatment. He hoped to avoid 
firing, so I gave him some ointment to blister with. When he 
took her home he applied it, but it did no good, except to de¬ 
velop the enlargement. So the last week in December we 
tried her three times with different solutions of cocaine, hoping 
to produce anaesthesia and fire her. The first solution was gr. 
vii to 100 minims; second solution was gr. xv to 100 minims; 
third time I took gr. xxv to 100 minims, and rubbed it in over 
the plantar nerve, hoping to be able to inject the needle through 
the skin without causing pain, and by this measure to aid the 
subcutaneous injection, which was a solution gr. xxx to 100 
minims, and at no time would she allow us to touch her leg 
with a pin or bare hand, and her eyes were blinded; nor would 
she allow this done with a twitch on, but became very nervous 
and had spasmodic contractions of the hind limbs like a string- 
halted horse; she would kick and paw with this foot (right fore), 
and showed great excitement. The owner said after she was 
taken home she laid down and seemed to suffer as with colic. 
On January 1, 1894, I gave her an ounce ball of chloral, cast 
her, and finished my task. The ounce of chloral only had the 
effect of bringing her spirit down to about the level of the aver¬ 
age horse. She was not unsteady in her gait in the least, and
