Experiment CXXW 
The triceps mufcle of the thigh being 
detached from a frog, was put in contact 
with the thigh of another, the nerves of 
which were coated. 
The application of the conductor to 
the coating of the triceps excited convul- 
lions and contractions in the frog, but not 
in the mufcle. 
In thefe experiments, the live animal, 
the extremities, and the ifolated mufcle, 
ferved as the chain. The electrical fluid 
palTed along them, but they never ex- 
hibited the leaf! fign of motion. 
If the eleCtricity did not excite any mo¬ 
tion in the parts, which ferved as con¬ 
ductors, why did it excite movements in 
prepared frogs furnifhed with coatings ? 
Can this queflion be refolved by the 
hypothefis of our antagonift? Does not the
