Experiment V. 



I divided tranfverfely all the parts of a frog at the pelvis, 

 then tied together the divided parts of one of the fciatic nerves 

 with a linen thread. I afterwards pafTed the tinfoil around the 

 nerve, at a considerable diftanee above the ligature, and found, 

 that when, with a brafs wire, I prefled the tinfoil againft a 

 half crown piece, laid on the table at a little diftanee from the 

 frog, the mufcles of the leg were inftantly convulfed. 



Experiment VI. 



When, after dividing both fciatic nerves tranfverfely, I tied 

 the upper part of the right fciatic nerve, inclofed in the tinfoil, 

 to the lower part of the left fciatic nerve, and then, with a 

 brafs wire, prefled the tinfoil againft a piece of filver, the 

 mufcles of the left leg were convulfed.

The event was the fame when the divided parts of the 

 nerves were crofled over each other, without being tied toge- 

 ther.
