As the medium of space furnishes all the nerves with the true and only cerebral exciting fluid, which is necessarily all-pervading, and proved to be so by the auditory sense, or "hearing through stone walls," the possibility of seeing through such bodies is made manifest, and _clairvoyantly_, has been proved. Misled by the idea that the eye-balls look through solid glass, yet cannot look through a stone, to doubt and deny is pardonable; yet nothing else is requisite, than that the visual medium shall be continuous from the object to the brain, no matter how many opaque objects lie between, for the perception being excited, and promoted by the remote object: the object perceived is the sensation of this or that colour, as in transparent vision. It is no ordinary circumstance, that of "seeing through opaque bodies;" neither is it an ordinary circumstance, the extreme de-electrised condition of the nervous fluid, _on which the extra-ordinary of the phenomenon depends_. In removing the partial opacity of a crystal by means of fire, the hindrance to the visual continuity, electric matter, is displaced; but as no such electric displacement from a stone wall is effected or practicable, while to the clairvoyant the continuity is as were there no electric impediment in the wall, is proof additional that the medium of space, the common cerebral exciting cause, pervades all things, the human body included, and hence the being in _Report_. Now that mesmeric practice and proof have stifled all open opposition, by the influential ignorant, to the surprising truths of the science, that all persons cannot be mesmerised to the clairvoyant stage, is in nowise prejudicial to mesmerism, or to the SCIENCE OF THE ECONOMY being intimately connected with medical practice; neither are occasional failures by the clairvoyant, especially in trial tests, some of which exhibit samples of complicated confusion, as if for the purpose of suppression, instead of laudably exalting the all-important science of mesmerism. Had the very liberal offer of a hundred pounds been under less complicated conditions, the bank-note most certainly would have been deciphered and changed hands. Had the note been spread open, while enclosed between two plates of sheet-iron, and then read by the clairvoyant, the test would have been sufficient to convince the most steady, sturdy, staunch unbeliever, and the _dénouement_ affirmative to every dispassionate observer. But from being folded line upon line, letter on letter, at least three deep, the misarrangement destroyed most effectually all reading order. A Newtonian would say, that, "the commixed rays proceeding from the several overlaid typographic characters, and from the lines placed tier over tier, could never form the image of even a single letter on the retina, with anything resembling legible clearness;" therefore the trial must fail most inevitably.
