 about the end of the feventh hour from 

 the beginning of the experiment, it could 

 jump with almoft its wonted vigour; and

 peared free and rapid.

 leg only, that leg feemed to be fomev>fhat, 

 but not very confiderably, more benumb- 

 ed than the other ; yet the circulation did 

 not ceafe fooner in the one, than in the 

 other leg.

After the mixture had been applied 

 to the hind legs of two other frogs for 

 near an hour, I cut them off and fldnned 

 the fore part of the body, and then infu- 

 fed its mufcles and the bowels in wa- 

 ter, and diftindly perceived the fmell 

 and taHe of the fpirit in the water.
