You cannot _see_ the gas, yet it affects the person. You cannot see the subtile power conveyed from one man to a weaker. He conveys it by touch--nerve to nerve. I believe science will yet discover just what this subtile agent is--both in the blood and nerves; for it is in both, or why does the suspension of it in one destroy the other? Destroy the nerve, and the corresponding blood-vessel is inactive. Destroy the blood-vessel, and the corresponding nerve suffers. It is the power that the mother exercises to hush her sobbing babe to slumber. As the child gathers strength of mind, she loses that control. A person may be used as a mesmeric subject until he becomes a mere idiotic machine. Educate a clairvoyant doctor, and what becomes of his clairvoyant power? It is lost with the increase of intellectual power. Now, is this a "divine" quality, that only ignorance can make use of? Is it really "hidden from the wise and prudent, and given to babes?" All sciences were practised by the uneducated first, before being reduced to a _science_. I think this will be yet reduced to a useful science. As it now stands, it is useless. If it is a spirit power, the spirits are mighty silent as to the fact. We come into this world by natural causes. We live, grow, exist, and we die by natural causes. We brought no knowledge with us; we carry none out. All the qualities yet developed in man are natural, and adapted to this life. Millions upon millions have so lived and so died, and a spirit power in _this_ world is no nearer to being established than it was when Adam was a little boy. All that heretofore has been attributed to spirit, or supernatural causes, has been proven to be but natural. I claim that magnetism and the undiscovered sciences are natural, and have no connection with the next world, to which we tend. The human eye, to some extent, is magnetic. A blind man cannot thrill an audience; hardly can an orator with glasses over his eyes. Dr. Chapin approaches the nearest to it. Dr. Beecher's great magnetic power is in his eyes, and is also let off at the ends of his fingers. But to _thoroughly_ magnetize a person, he must be _touched_. POWER OF THE HUMAN EYE.
