It is at least remarkable that the electro-motive values of the discharge in the cases of the eye- ball and of the skin are of the same order of magnitude as that calculated for a single plate of the electrical organ ( to ). According to a recent estimate by Gotch,* the of nerve in response to a single induction shock reaches a value not far short of thisâviz., volt. And the very points where the comparison is defective should serve to instigate further study. Thus the organs of Torpedo, Gymnotus and Raia are * Gotch and Burcli, Proc. Roy.
