The advantages of the application of 
blifters, according to the method propofed 
and pradtifed by the celebrated Cotunnio, 
are better explained by the fa<£t under con- 
ficeration, than by the hypothefis of the 
author. 
Experiment LIX. 
I have likewife enveloped with opium 
the tibia of live frogs, after having de¬ 
tached the mufcles without deranging the 
larger nerves. The leg did not become 
paralytic. On killing the animal and fub- 
mitting this leg to the experiment, it has 
experienced more violent contra&ions than 
the other, to which opium had not been 
employed. Ten times I have repeated 
this experiment, and as often the fame 
circumftance has enfued. How extremely 
difficult of explanatioii is this phenomena!
