The patient was stripped, and the Torpedo placed successively to the joints trunk, and extremities, so that the whole of the body and limbs were permeated in their turn by the electric shock. That the stroke of the Torpedo is veritable electricity is a fact which was once much ilLsputed, but IS now conclusively proved by a host of experiments. Needles have been niagnetisod by it as if the shock had been that of a galvanic batterv, the electrometer sliowed decided proofs of the nature of tlie tluid that had been sent tlirouoh it and even the electric spark has been obtained from the Torpedoâvery small, it is true but still recognisably apparent. It is rather curious, that in the course of the experiments it was iliscovered that the upper surface of the Torpedo corresponded with the copper plate of a battery, and the lower surface with the zinc plate. The structure of the electrical organ is far too complex to be fully described in this uork, as It would require at least forty or fifty pages, and a large number of illustrations 1 will, however, give a brief summary of the strange organ by which such wonderful results are obtained, and any of my readers who would like to examine it more in detail will hiid ample inlormation in an article on the subject by Dr. Cohlstream in the â â¢Cyclopaedia of and Physiology," and from a valuable series of wax models in the museum of the College of Surgeons. Biietly, then, this organ is duplex, and consists of a great number of columns, placed closely against each other, each inclosed in a very thin niembrane. The
