40 EFFECTS OF 



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 ex- 

 tremities ; the respiration was laborious, it was 

 gradually performed at longer and longer in- 

 tervals, and at the end of an hour and fifteen 

 miniates had entirely ceased. Two minutes after 

 the animal was apparently dead, I opened into 

 the thorax, and found the heart acting with mo- 

 derate force and frequency, circulating dark- 

 coloured blood. I introduced a tube into the 

 trachea, and produced 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. 



EXPERIMENT IV. 



I injected into the stomach of a rabbit two 

 ounces of proof spirits. The injection was scarcely 

 completed, when the animal became perfectly 

 insensible. Precisely the same symptoms took 

 place as in the last experiment, and at the end 

 of twenty-seven minutes from the time of the 

 injection, the rabbit was apparently dead; but 

 on examining the thorax the heart was found 

 still acting, as in the last experiment. 



It has been shown by M. Bichat, and the ob- 

 servation has been confirmed by some experi- 

 ments which I have lately had the honour of
