I should add, also, that in most cases the subject of the experiment was kept in ignorance of the fact that a rise of the thermometer was to be expected.

Is it not possible that the current even of an induction battery has the power so to stimulate the tissues as to cause an increase in the ordinary rate of disintegrative change?
Perhaps a careful study of the secretions might lend force to this suggestion.
That the muscular action produced by the battery is not essential to the increase of bodily heat is shown by the next set of facts to which I desire to call attention.
Some years ago, Messrs.

Beard and Rockwell stated that when an induced current is used for fifteen to thirty minutes daily, one pole on the neck and one on either foot, or alternately on both, the persistent use of this form of treatment is decidedly tonic in its influence.

I believe that in this opinion they were perfectly correct, and I am now able to show that, when thus employed, the induced current causes also a decided rise of temperature in many people, which proves at least that it is in some way an active agent, capable of positively influencing the nutritive changes of the body.
The rise of temperature thus caused is less constant, as well as less marked, than that occasioned by the muscle treatment.

I do not think it necessary to give the tables in full.
