Of the{001} origin of medicine but little need be said by way of preface, save that it must have been nearly contemporaneous with the origin of civilization. The lower animals when sick or wounded instinctively lessen or alter their diet, seek seclusion and rest, and even in certain cases seek out some particular herb or healing substance. Thus, too, does the savage in his primitive state; and experience and superstition together have led nearly all the savage tribes into certain habits and forms in case of injury or disease. For us the history of medicine must necessarily begin with the written history of events, and its earliest endeavors need detain us but a very short time. Its earliest period is enveloped in profound obscurity, and so mingled with myth and table as to be very uncertain. It embraces an indefinite time, during which medicine was not a science, but an undigested collection of experimental notions,--vaguely described, disfigured by tradition, and often made inutile by superstition and ignorance. The earliest records of probable authenticity are perhaps to be met with in the Scriptures, from which may be gathered here and there a fair notion of Egyptian knowledge and practice. Thus we read that Joseph commanded his servants and physicians to embalm him, this being about 1700 B.C.. It shows that Egypt at that time possessed a class of men who practiced the{002} healing art, and that they also embalmed the dead, which must have both required and furnished a crude idea of general anatomy. We are also informed from other sources that so superstitious were the Egyptians that they not only scoffed at, but would stone, the embalmers, for whom they had sent, after the completion of their task. The probably mythical being whom the Egyptians called Thoth, whom the Greeks named Hermes and the Latins Mercury, passed among the Egyptians as the inventor of all sciences and arts. To him are attributed an enormous number of writings concerning all subjects. Some have considered him as identical with Bacchus, Zoroaster, Osiris, Isis, Serapis, Apollo, and even Shem, the son of Xoah. Others have thought him to be a god. It is now almost certain that the books attributed to Hermes were not the work of anyone hand or of any one age. The-last six volumes of the forty-two composing the encyclopaedia, with which Hermes is credited, refer to medicine, and embrace a body of doctrines fairly complete and well arranged. Of these six, the first treats of anatomy; the second, of diseases; the third, of instruments; the fourth, of remedies; the fifth, of diseases of the eye; and the sixth, of diseases of women. In completeness and arrangement it rivals, if not surpasses, the Hippocratic collection, which it antedated by perhaps a thousand years. The Egyptians appear at first to have exposed their sick in public (at least, so says Strabo), so that if any of those who passed by had been similarly attacked they might give their advice for the benefit
