The following trite sketch of the Philosophy of Nature, dedicates itself to the most noble Champions of Mesmerism, Doctor Elliotson and Doctor Ashburner of London, and Doctor Esdaile of Calcutta, in compliment and grateful acknowledgment for having rescued from the fangs of ignorance, envy, and self-conceit, the science of health and knowledge—the science of Mesmerism, which unfolds the hitherto unknown wonders of the Animal system; and will unfold the wonders of the entire universe, when the telescope and microscope are familiarly used by the Clairvoyant.
