William Richards of this city, who met Brownson at the Catholic Congress several years ago, gave Heydenfelt access to his library and called his attention to "Spirit Rapper, An Authobiography", in connection with a subject the latter has been investigating— electro-magnetizing the use of the galvanic battery, through distributing subjects and others; the system so largely practiced in India and among the Druids and other secret orders of the United, who have what is termed spiritual governments, like the one among the Mormons, a system by which citizens not belonging to any secret orders are magnetized, connected with members of these orders, and whose minds can be read and thoughts transferred. Heydenfelt has explained the subject in a pamphlet treating the methods of electro-magnetizing and hypnotism, entitled "The Unison of the Conscious Force", a copy of which he sent to the Secretary of State of Michigan. His object in visiting Washington is to examine the books in the office of the Surgeon General and in the Congressional and other libraries on these subjects and kindred ones. So few know the extent to which electro-magnetizing is carried on in the U. S. that his object is to explore it, make known its dangers, and to move the attention of the people so that they will demand legislation in the states and in Congress. He would like to have placed at his disposal any memoranda of Orestes A. Brownson on the subject. He has heard that magnetism or hypnotism was practiced on a large scale during the late war between France and Germany. He asks for aid in verifying what he has heard and read of its use in France in 1848. He will remain here several weeks, then visit the South before returning to his law practice in San Francisco. :: III-3-d A.L.S. 1p. 8vo.
