muria of fea-falt and nitre all over itj and after a 
very few minutes I laid the raifed part of the tendon 
in its natural direction, upon the correfpondent fixed 
part, and they were both exadly congruous j fo that 
the loole part had not contracted itl'elf, nor was at all 
fhorter, after thefe repeated trials, than its corre- 
fpondent fixed part. I then put the creature on its legs, 
to fee whether it had fuffered fo much, that it could

about five minutes torment, the butcher ended all its 
pains, and I performed the fame procefics on a flieep

I was induced to make two other very cruel ex- 
periments on different animals, by laying bare their

•fluids had fpread over the furface, fo as to reach the 
extremity of the fkin, the creature underwent as 
much pain as cutting before had caufed. 
I defired the butcher to take off as much fkin 
from the forehead, as was neceffary to perform the

the inflrument to the flieep’s forehead, I vellicated 
the pericranium with the end of a knife, but could 
not obferve the membrane fenfible, or thereby thrown 
into contractions j and when the operation was over, 
and the bone taken from the fubjacent dura mater,
