This experiment serves to confirm the results of the preceding one, and shows, 
further, that the muscles of the poisoned and non-poisoned legs were equally little 
affected. 
Exp. LXIV.— May 20, 1874. 
Erog. — Weight 23 grms. 
Dose 1 cub. centim. of the 5 per cent, solution (50 milligrammes V 2 0 5 ), 
injected under the skin. 
In this case the whole thigh, except the sciatic nerve, was compressed firmly by a 
ligature. 
Father more than half an hour after respiration had ceased, but before paralysis was 
general, the frog was decapitated, and the sciatic nerves tested as in the preceding 
cases. 
This experiment confirms the results of the preceding ones, showing that the non- 
poisoned and the poisoned muscles and nerves are equally irritable.
