Book excerpt: Excerpt from An International System of Electro-Therapeutics: For Students, General Practitioners, and Specialists In connection with these observations he mentions two hypotheses (1) that the current, on account of its enormous frequency, passes by the surface of the body as such currents are known to do with other con ductors, and (2) that the sensitive and motor nerves are so organized as to respond only to vibrations of a definite frequency, in the same way that the terminations of the optic nerve are' blind for undulations Of the ether of a period less than 497 billions per second (red), or more than 728 billions per second (violet). He rejects the surface theory so far as the animal body is concerned, and, though he passed currents of 3000 milliamperes, he explained their harmlessness by absence of excitation, or, rather, on the hypothesis that these currents exercise, on the nervous centres and muscles, an inhibitory action of the kind studied by Dr. Brown-sequ'ard; and he considers that this inhibitory action is shown by some of the phenomena above described.
