From the INTRODUCTORY. There has been a revolutionary action going on in my mind to which, twenty years ago, I said "Stop!" It stopped not, but the end is now. If a demonstrator of anatomy will give a natural, rational and practical solution of the reason why nerves uniformly accompany the arteries and not so uniformly the veins in, the human system, which they have failed to do up to time of publication, I think I can prove, on a rational and natural basis, that the heart does not circulate the blood, but that the positive and negative electricities, generated from the air in the lungs and from them conveyed to the brain, thence distributed through the system to supply the natural demands of the body, circulate the blood and are the physical life and the motive power of the body, acting in harmony with the spirit life; this may be likened unto the electricity, positive and negative, generated by steam, by water power or other known generative power of electricity, the principles of which are attraction and repulsion, push and pull, motive force or power. Everything is kept in motion by it as long as the power lasts or until the machinery wears out. So with the body. As long as you take air into the lungs, the machinery of the body will be kept in motion, until the machinery is worn out or destroyed by disease or outside influences, etc. Spinal meningitis, congestions and inflammations of the human system can be explained and removed on scientific principles. Will wood and water run an engine without^ steam? Is not steam the motive power of the engine? Can you force water through a pump without a motive power? Will electric cars run without a motive power? Are not horses the motive power of our street cars ?
