Excerpt from book: of the arc of zinc and silver, the silver being under the lumbar tissues: In four minutes we raised the spinal marrow from the zinc; there was tetanus. We again raised it in five minutes more, and then divided the spinal marrow close to its lower part; the tetanus ceased instantly. Ex. 8. If the frog be prepared as in fig. 2, and the Voltaic circuit be inverse or upward in the spinal marrow; and if a and c be connected, there are movements in the corresponding extremities; viz., a and c; if b and d be connected there are movements in b and d; and on breaking the circuit there is tetanoid spasin in the lower extremities c and d. On reversing the Voltaic current and breaking the circuit, there was no tetanus. On recompleting the circuit and connecting the Voltaic wires, there were strong movements in all the limbs. On breaking the circuit and connecting, there were still movements, but they were slight. Ex. 9.?On repeating the experiments described in fig. 2, with the inverse current, there were movements in all the limbs on connecting e and f; on connecting e or f and a, there were movements in a; on connecting e or f and b in b; e or/and c in c; e or/and d in d; on connecting a and c, b and d, a and b, and c and d, no effect was observed.

The physiologist acquainted with the recent progress of our knowledge of the nervous system will readily imagine the importance of the next question to be submitted to the Society, viz., whether the incident spinal nerves, as well as the spinal centre itself and the muscular nerves, are susceptible of the electrogenic state, with its independent phenomena. It was difficult to submit this question to the test of experiment. It was difficult to denude and isolate inc...
