ExPERIMENT V. 
I pivipEp 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 paffed the tinfoil around the 
nerve, at a confiderable diftance 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 diftance from the 
frog, the mufcles of the leg were inftantly convulfed. 
ExPERIMENT VI. 
Wuew, after dividing both {ciatic 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, preffed the tinfoil again{ft a piece of filver, the 
mufcles of the left leg were convulfed.
