i8o Mr. Brodie on the dijfemit Modes, 
the oesophagus of a cat. Instantly he struggled violently ; 
then lay on one side, perfectly motionless and insensible ; the 
breathing was laboured and stertorous, and the pulsations of 
the heart were very frequent. He continued in this state for 
seven or eightmainutes ; then began to recover ; the respira- 
tions became easier, and presently he stood up, and was able 
to walk. 
Exp. 2. I injected an ounce and a half of proof spirits into 
the stomach of a large full-grown rabbit, by means of an 
elastic gum tube passed down the oesophagus. The same 
symptoms took place as in the last experiment; but the ani- 
mal did not begin to recover from the state of insensibility, 
until forty minutes had elapsed from the time of the injec- 
tion. 
Exp. 3. Seven drams of proof spirits were injected into the 
stomach of a younger rabbit. Two minutes afterwards, he 
evidently was affected by the spirits, and in three minutes 
more he lay on one side motionless and insensible. The pupils 
of the eyes were perfectly dilated; there were occasional 
slight convulsive motions of the extremities ; the respiration 
was laborious, it was gradually performed at longer and 
longer intervals, and at the end of an hour and fifteen minutes 
had entirely ceased. Two minutes after the animal was ap- 
parently dead, I opened into the thcrax, and found the heart 
acting with moderate force and frequency, circulating dark 
coloured blood. I introduced a tube into the trachea, and pro- 
duced artificial respiration by inflating the lungs, and found 
that by these means the action of the heart might be kept up 
to the natural standard, as in an animal from whom the head 
is removed.
