holding ninety thousand spiritual conferences, he was brought back again to his bed; all which was transacted in so small a space of time that Mohammed, upon his return, found his bed still warm. Are dreams so much varied as is generally supposed? Or, taking into consideration our different mental and physical constitutions, is there not rather a remarkable sameness in them? It is certainly a very unusual circumstance to hear of any dream that does violence to the common experience of mankind. One class of dreams, which may be termed RETROSPECTIVE, is of frequent occurrence. These are characterized by the revival of associations long since forgotten. The faculty of Memory appears to be preternaturally exalted; the vail is withdrawn which obscured the vista of our past life; and the minutest events of childhood pass in vivid review before us. There can be no doubt that something analogous to this occurs in drowning; when, after the alarm and struggle for life has subsided, sensations and visions supervene with indescribable rapidity. The same very remarkable phenomenon takes place also sometimes in hanging; but is by no means uniformly produced. "Of all whom I have seen restored from drowning," observes Dr. Lettsom, "I never found one who had the smallest recollection of any thing that passed under water until the time they were restored." Persons must not, therefore, be deceived by imagining that an Elysium is to be found at the bottom of a garden-well, or a canal, or a river.
