The curare experiment may be thus performed: Lift up the sciatic nerve of a frog, and ligature the whole limb (ex- clusive of the nerve) so that no blood may reach the muscles; then inject curare, which paralyzes nerves but not muscles, into the general circulation through the posterior lymph-sac. On stimulating the sciatic nerve the muscles of the leg beneath the ligature contract, while no contraction of the muscles of the opposite leg follows from stimulation of its sciatic nerve. In the latter case the curare has reached the nerve terminals through the blood; in the former, these were left uninfluenced by the poison. If, now, the muscle itself be directly stimulated in the latter case, contraction follows, from which it is con- cluded that curare has dastroyed the functional capacity of the nerve {ierminals), but not of the muscle. 2. Stimulation of those parts of muscles in which no nervous terminations have been found, as the lower part of the sartorius muscle in the frog, is followed by contraction. 3. Certai
