of that intensity which induces light visible to the eye. Even then he will not have reached the compound interetheric - the border line to the introductory luminous.

It is evident that Tesla already comprehends the law governing transmission and dissociation in electrical alternation with regard to its reception by the physical organism, whereby an increase of the number of volts that prove fatal to life are harmless, and given without any risk to the subject. The ear is not susceptible to the vibrations of inaudible sounds; nor the eye to those of light beyond the number necessary for sight. A wheel having five spokes and making ten revolutions per minute gives fifty alternations on the spokes, which are readily counted by the eye; whereas an increase in the revolutions, to five hundred in ten minutes, increases the alternations of the spokes beyond the power of the retina to receive and count.

It is the same with electrical alternation in regard to its receptiveness by the physical organism. Phenomenal as it may seem to those ignorant of the fact, this is a standard truth in sympathetic physics, which Tesla's penetration did not fail to discover. The plane of research that he occupies in regard to electrical phenomena, is as much above that of his fellow electricians as is the plane occupied by Keely (in researching the problem of aerial navigation) beyond the realm in which those inventors are working, who are constructing balloons and flying machines on various principles, while still ignorant of a force in nature that is antagonistic to gravity and overcomes it; thus making navigation of the air, with ships of thousands of tons burthen, both possible and perfectly safe.

Electricians will no longer remain captive in their domain when Keely's system is published to the world; as it will be when he has effected the settlement that he seeks. If this settlement is not effected, without the delay of litigation, his secrets will die with him, in all probability, for no one but himself knows the process by which dead metal is sensitized so as to be operated upon, as the brain is operated upon by celestial radiation.
