With the disposition, then, to ‘pooh-pooh’ the discovery in London, I think it will probably be left to America—perhaps to you!—to evolve the truth. Therefore I shall feel it my duty to put you in possession of facts bearing upon it. I have, however, had the satisfaction of seeing conviction produced on the mind of one of our most distinguished geologists, who perceived the connection between the influences of magnetism and metals on the pendulum, and some of the subterranean operations, particularly mineral springs. (My hand is tired and must rest.) The application of magnetism to the principle of life is most satisfactory to me. The unification of the magnetism of the human head by finding that the pendulum is influenced by it, exactly as by a real magnet, that the poles correspond, the forehead being north when the person is upright. (Changes take place in the recumbent position.) This is when a person stands in any direction, _live_ bodies being _independently_ magnetic. It is the case even with an egg new laid. After boiling, _that_ power ceases, and it is a magnet only _by induction_, like any other inorganic matter. In trying experiments the feet must not be crossed, nor the legs, nor the hands clasped, nor thumbs joined. These attitudes all occasion the motions to stop—for they complete this circuit—analogous to electrical phenomena. After all, I have not told you what appears the most curious fact in its consequences, that (as far as yet tried) the body loses its influence on the magnetoscope in sleep. Its polarity is gone, as in death! ‘Twin brothers!’ On reading over what I have written I perceive a want of explicitness, which I hope the pamphlet will make up. I will divide it into sheets to be sent in letters. With a strong feeling that the ocean is not distance, Yours most truly, _A. I. Noel Byron_. At this time I employed the leisure hours of a young physician in preparing some lectures on the physical education of girls, which were delivered in a basement Sunday school room in the spring of 1852.
