Still less should we raise an objection on the manifest improbability of this vigilant observer, a convalescent too, being able to keep upon his legs, running or walking, the whole of the night and of the next day, (to say nothing of the pedestrian powers of the old man.) In a picture of this kind, a moral idea is sought to be portrayed by imaginary incidents purposely exaggerated. The mind passing immediately from these incidents to the idea they convey, regards them as little more than a mode of expression of the moral truth. He who should insist, in a case of this kind, on the improbability of the facts, would find himself in the same position as that hapless critic who, standing before the bronze statue of Canning, then lately erected at Westminster, remarked, that "Mr Canning was surely not so tall as he is there represented;" the proportions, in fact, approaching to the colossal. "No, nor so green," said the wit to whom the observation had been unhappily confided. When the artist made a bronze statue, eight feet high, of Mr Canning, it was evidently not his stature nor his complexion that he had designed to represent. Amongst the tales of Mr Poe are several papers which, we suppose, in the exigency of language, we must denominate philosophical. They have at least the merit of boldness, whether in the substratum of thought they contain, or the machinery employed for its exposition. We shall not be expected to encounter Mr Poe's metaphysics; our notice must be here confined solely to the narrative or inventive portion of these papers. In one of these, entitled "Mesmeric Revelations," the reader may be a little startled to hear that he has adopted the mesmerised patient as a vehicle of his ideas on the nature of the soul and of its immortal life; the entranced subject having, in this case, an introspective power still more remarkable than that which has hitherto revealed itself only in a profound knowledge of his anatomical structure. As we are not yet convinced that a human being becomes supernaturally enlightened--in mesmerism more than in fanaticism--by simply losing his senses; or that a man in a trance, however he got there, is necessarily omniscient; we do not find that Mr Poe's conjectures on these mysterious topics gather any weight whatever from the authority of the spokesman to whom he has intrusted them. We are not quite persuaded that a cataleptic patient sees very clearly what is going on at the other side of our own world; when this has been made evident to us, we shall be prepared to give him credit for penetrating into the secrets of the next.
