The chloroform administered freely on a cloth cap with a sponge
inside. The respiration was in mere gasps for some time
before its final cessation. The dog continued to yelp for some
time after the cornea became insensible. Artificial respira-
tion fur three minutes failed to restore the pulse or respiration.
P.-M.—Lungs healthy. Pulmonary veins much distended.
Right, auricle and ventricle full of blood. Left side empty.
A leather muzzle was used to control the dog, which probably
caused some constriction of the neck. Temperature of room
255º per cent.

Chloroform as in No. 1. In place of the leather muzzle a simple
loop of rope was fastened round the jaws and tied behind the
ears until the dog became quiet, so that no pressure was exer-
cised upon the neck. The dog continued to yelp and groan
for 47 seconds after the cornea became insensible. P.-
