hibernation; in that process, of course the circulation would be as completely checked as the respiration; thus there would be no waste, and the absorbents (which would also be absolutely dormant) would not have to do even that slight amount of work which they accomplish during hibernation. Science can only say that the known cases of hibernation among warm-blooded animals show that the vital forces may be reduced much lower without destroying life, than but for them we should have deemed conceivable. But next let us consider what science has to say as to the artificial suspension of vitality. In Dr. Richardson's paper on this subject there is much which seems almost as surprising as anything in the Australian story. Indeed, he seems scarcely to have felt assured that that story really was a hoax. "The statements," he says, "which, under the head of 'A Wonderful Discovery,' are copied from the _Brisbane Courier_, seem greatly to have astonished the reading public. To what extent the statements are true or untrue it is impossible to say. The whole may be a cleverly-written fiction, and certain of the words and names used seem, according to some readers, to suggest that view; but be this so or not, I wish to indicate that some part at all events of what is stated might be true, and is certainly within the range of possibility." "The discovery," he proceeds, "which is described in the communication under notice, is not in principle new; on the subject of suspension of animation I have myself been making experimental inquiries for twenty-five years at least, and have communicated to the scientific world many essays, lectures, and demonstrations, relating to it. I have twice read papers bearing on this inquiry to the Royal Society, once to the British Association for the Advancement of Science, two or three times in my lectures on Experimental and Practical Medicine, and published one in _Nature_. In respect to the particular point of the preservation of animal bodies for food, I dwelt on this topic in the lectures delivered before the Society of Arts, in April and May of last year (1878), explaining very definitely that the course of research in the direction of preservation must ultimately lead to a process by which we should keep the structures of animals in a form of suspended molecular life." In other words, Dr. Richardson had indicated the possibility of doing precisely that which would have constituted the chief value of the Australian discovery, if this had been real.
