“‘Before proceeding to demonstrate the truth of Hamlet’s remark to Horatio,’ said the experimenter at my side, ‘I find it essential to give you a why and wherefore. Know, then, that not only is there a mysterious and powerful sympathy between man’s body and all things outside of it, but it is still more true that a greater one exists between these outside things and his soul within, as is proved by the astonishing power over it exerted by various substances, most of which, especially the last eight, ought to be banished from the earth and be accursed for ever--for instance, Belladonna, Cantharadin, Beng, Opium, Hasheesh, Dewammeskh, Hyndee, Tartooroh, Hab-zafereen, Mah-rubah, Gunjah, and many other vegetable preparations that might be named, and every one of which will not merely affect the body, but the tremendous mystery that lies concealed within it. They expand the soul, but they also damn it! Let us ascend from gross matter to the volatile--Light, for instance. By concave mirrors we can throw an image in open space that shall be seen by thousands. We chain a shadow, and whoever has a photograph possesses one such prisoner. We make a few passes over a glass of water, and charge it thus with any specific quality we choose, nauseous or pleasant, and it produces corresponding effects upon the patient who takes it. Here you have mind and matter united by an act of mere volition. But we go still farther: for we select materials, and with them render the water still more highly sensitive. We then charge it with our souls, to such an extent that it shall comatize a man’s body, and illuminate his soul to the sublimest degree of clairvoyance. Still higher: it is possible to compound a liquid that shall seize on, and for a time retain, by its subtle power, any mental image thrown upon it. Still higher: there are direct and positive affinities and co-relations between every thing and person on this earth and off it. By certain knowledge, certain persons are able to select those things that possess certain affinities to and for the inhabitants of the upper worlds, and the dwellers in the Spaces. Now that glass disk before you contains such a liquid, thus compounded--’ “Here he gave me the most minute explanations of the process of constructing such curious mirrors, and how to charge them with a liquid which I at once saw must of necessity be electrical, magnetic, highly odyllic and ethereal. Then he told me how to charge it differently for different uses--as a toy, a means of medical diagnosis, for the purpose of interpreting dreams, seeing earthly things, discovering lost treasures, reading the past or the future, and for many other purposes, as no one mirror would serve more than one end, or work in more than a single direction, unless specially constructed for such general use, which would render them too costly.
