A fourth discovery, perhaps of equal rank, was the discovery by Harvey's contemporary, Aselli, of the lacteals that absorb the chyle. A fifth discovery or discoveries of importance was that of the corpuscles of the blood, and the Malpighian bodies of the kidneys, by Malpighi. A sixth discovery, considered more important and occupying a larger space in medical literature, is the cell doctrine of Schwann, a doctrine still under discussion and by no means a finality. Anatomical science has few first class discoveries. Anatomy has been a growth of observation and description--not discovery. Vesalius and Eustachius may be considered the fathers of modern anatomy, and the name of the latter is immortalized by the Eustachian tube, which he first recognized and described. But the Fallopian tubes, named after Fallopius, were not his discovery. They had been described long before by Herophilus and others. Eustachius was nearly two centuries ahead of his age in anatomy, and should be gratefully remembered as a struggling scientist. His valuable anatomical works, which he was too poor to publish, were published one hundred and forty years after his death, by Lancisi. From this brief glance at the discoveries of Eustachius, Harvey, Aselli, Malpighi, Gall, Majendie, and Schwann, it is apparent that but one physiological discovery on record is sufficiently important in its nature and scope to be compared with sarcognomy, which comprehends the relations of soul, brain, and body. What is their relative value? Gall's discovery embraced about one half of the psychic functions of the brain, with nothing of its physiological functions. Sarcognomy, on the contrary, embraces the entire mass of cerebral functions to connect them with corresponding functions in the body. It presents in one complete view the psychic powers in the soul operating in the brain, and extending their influence into the body; and on the other hand, the physiological powers of the body, operating through the brain, and by definite, intelligible laws acting upon the soul--a vast system of science, based on anatomical facts, but evolved by experiment, to which no single volume could do justice. Its medical applications alone, concisely presented in thirty lectures, would make a volume of four hundred pages.
