No Physiological Reason for Death.--"Dr. William A. Hammond, a prominent physician of New York, who has written several medical treatises, and was some years ago Surgeon-General of the United States Army, has recently set forth his belief that there is no physiological reason at the present day why man should die. He maintains that people die through the ignorance of the laws which govern their existence, and from their inability, or indisposition, to attend to those laws with which they are acquainted. Now, as the business of medical men has ostensibly been for the last four thousand years to prolong human life, and as Dr. Hammond affirms that there is no good reason why people should die, the wonder is why men of his school have not drawn up some formula by which they could live on for three or four thousand years, at least. There has always been a vague impression that the knowledge of the preservation of human life had been lost, and that in some favored era of the world's history that knowledge would be recovered. "If there is such a thing as a hidden law of life, which, when discovered and asserted, will arrest physical decay and prevent death, except by accident, Doctor Hammond, and all who hold to his doctrine, ought to lose no time in making it known. This medical authority reasons that, as the human body is constantly dying and constantly renewing its particles, this law of displacement and renewal ought to be perpetual, and that when it is discovered just what substances are best fitted to maintain this equipoise, as it were, there should be no giving out of the physical powers. "'The food that man takes into his stomach,' says Doctor Hammond, 'ought to be of such quantity and quality as would exactly repair the losses which, through the action of the several organs, his body is to undergo. If it is excessive in either of these directions, or if it is deficient, disease of some kind will certainly be the result. If he knew enough to be able to adjust his daily food to the expected daily requirements of his system, disease could never ensue through the exhaustion of any one of his vital organs. A large majority of the morbid affections to which he is subject are due to a lack of this knowledge.
