Philadelphus founds medicine on anatomy. He authorizes dissection and human vivi section. who had charge of natural history, and was directed to write a book on Fishes. The elevated ideas of the founder cannot be better illustrated than by the manner in which he organized his medical school. It was upon the sure basis of anatomy. Herophilus and his colleagues were authorized to resort to the dissection of the dead, and to ascertain, by that only trustworthy method, the true structure of the human body. The strong hand of Ptolemy resolutely carried out his design, though in a country where popular sentiment was strongly opposed to such practices. To touch a corpse in Egypt was an abomination. Nor was it only this great man's intention to ascertain the human structure; he also took measures to discover the mode in which its functions are carried forward, the manner in which it works. To this end he authorized his anatomists to make vivisections both of animals, and also of criminals who had been condemned to death, herein finding for himself that royal road in physiology which Euclid once told him, at a dinner in the Museum, did not exist in geometry, and defending the act from moral criticism by the plea that, as the culprits had already forfeited their lives to the law, it was no injury to make them serviceable to the interests of humanity. Physicians of the Alexan- Herophilus had been educated at Cos; his drian school. pathological views were those known as humouralism; his treatment active, after the manner of Hippocrates, upon whose works he wrote commentaries. His original investigations were numerous; they were embodied, with his peculiar views, in treatises on the practice of medicine; on obstetrics; on the eye; on the pulse, which he properly referred to contractions of the heart. He was aware of the existence of the lacteals, and their anatomical relation to the mesenteric glands. Erasistratus, his colleague, was a pupil of Theophrastus and Chrysippus : he, too, cultivated anatomy. He described the structure of the heart, its connexions with the arteries and veins, but fell into the mistake that the former vessels were for the conveyance of air, the latter for that of blood. He knew that there are two kinds of nerves, those of motion and those of sensation. He referred all fevers to inflammatory states, and in his practice differed from the received methods of Hippocrates by observing a less active treatment. By these physicians the study of medicine in Alexandria was laid upon the solid foundation of anatomy. Improve pharmacy. Besides them there were many other instructors ments in in specialties; and, indeed, the temple of Serapis surgery and was used for a hospital, the sick being received into it, and persons studying medicine admitted for the purpose of familiarizing themselves with the appearance of disease, precisely as in similar institutions at the present time. Of course, under such circumstances, the departments of surgery and pharmacy received many improvements, and produced many able men. Among these improvements may be mentioned new operations for lithotomy, instruments for crushing calculi, for reducing dislocations, etc. The active commerce of Egypt afforded abundant opportunity for extending the materia medica by the introduction of a great many herbs and drugs. Decline of medicine. The medical school of Alexandria, which was thus originally based upon dissection, in the course of time lost much of its scientific spirit. But the influence of the first teachers may be traced through Alexandrian many subsequent ages. Thus Galen divides the profession in his time into Herophilians and Erasistratians. Various sects had arisen in the course of events, as the Dogmatists, who asserted that diseases can only be treated correctly by the aid of a knowledge of the structure and functions, the action of drugs, and the changes induced in the affected parts; they insisted, therefore, upon the necessity of anatomy, physiology, therapeutics, and pathology. They claimed a descent from Hippocrates. Their antagonists, the Empirics, ridiculed such knowledge as fanciful or unattainable, and relied on experience alone. These subdivisions were not limited to sects; they may also be observed under the form of schools. Even Erasistratus himself, toward the close of his life, through some dispute or misunderstanding, appears to have left the Museum and established a school at Smyrna. The study of the various brances of medicine was also pursued by others out of the immediate ranks of the profession. Mithridates, king of Pontus, thus devoted himself to the examination of poisons and the discovery of antidotes. What a fall from this scientific medicine to the miraclecure which soon displaced it! What a descent from Hippocrates and the great Alexandrian physicians to the shrines of saints and the monks! The Jewish physicians. To the foregoing sketch of the state of Greek medicine in its day of glory, I must add an examination of the same science among the Jews subsequently to the second century; it is necessary for the proper understanding of the origin of Saracen learning. Their emancipation from the supernatural. In philosophy the Jews had been gradually emancipating themselves from the influence of ancient traditions; their advance in this direction is shown by the active manner in which they aided in the development of Neoplatonism. After the destruction of Jerusalem all Syria and Mesopotamia were full of Jewish schools; but the great philosophers, as well as the great merchants of the nation, were residents of Alexandria. Persecution and dispersion, if they served no other good purpose, weakened the grasp of the ecclesiastic. Perhaps, too, repeated disappointments in an expected coming of a national temporal Messiah had brought those who were now advanced in intellectual progress to a just appreciation of ancient traditions. In this mental emancipation their physicians took the lead. For long, while their pursuits were yet in infancy, a bitter animosity had been manifested toward them by the Levites, whose manner of healing was by prayer, expiatory sacrifice, and miracle; or, if they descended to less supernatural means, by an application of such remedies as are popular with the vulgar everywhere. Thus, to a person bitten by a mad dog, they would give the diaphragm of a dog to eat. As examples of a class of men soon to take no obscure share in directing human progress may be mentioned Hannina, A.D. 205, often spoken of by his successors as the earliest of Jewish physicians; Samuel, equally distinguished as an astronomer, accoucheur, and oculist, the inventor of a collyrium which bore his name; Rab, an anatomist, who wrote a treatise on the structure of the body of man as ascertained by dissections, thereby attaining such celebrity that the people, after his death, used the earth of his grave as a medicine; Abba Oumna, whose study of insanity plainly shows that he gave a material interpretation to the national doctrine of possession by devils, and replaced that strange delusion by the scientific explanation of corporeal derangement. This honourable physician made it a rule never to take a fee from the poor, and never to make any difference in his assiduous attention between them and the rich. These men may be taken as a type of their successors to the seventh century, when the Oriental schools were broken up in consequence of the Arab military movements. In the Talmudic literature there are all the indications of a transitional state, so far as medicine is concerned; the supernatural seems to be passing into the physical, the ecclesiastical is mixed up with the exact: thus a rabbi may cure disease by the ecclesiastical operation of laying on of hands; but of febrile disturbances, an exact, though erroneous explanation is given, and paralysis of the hind legs of an animal is correctly referred to the pressure of a tumour on the spinal cord. Some of its aphorisms are not devoid of amusing significance: "Any disease, provided the bowels remain open; any kind of pain, provided the heart remain unaffected; any kind of uneasiness, provided the head be not attacked; all manner of evils, except it be a bad woman." them. At first, after the fall of the Alexandrian school, it was all that the Jewish physicians could do to preserve the learning that had descended to them. But when the tumult of Arabic conquest was over, we find The Arabs them becoming the advisers of crowned heads, affiliate with and exerting, by reason of their advantageous position, their liberal education, their enlarged views, a most important influence on the intellectual progress of humanity. Maser Djaivah, physician to the Khalif Moawiyah, was distinguished at once as a poet, a Rise of Jewish critic, a philosopher; Haroun, a physician of physicians to Alexandria, whose Pandects, a treatise unfortunately now lost, are said to have contained the first elaborate description of the small-pox and method of its treatment. Isaac Ben Emran wrote an original treatise on VOL. I. influence. 2 D They found medical colleges, poisons and their symptoms, and others followed his example. The Khalif Al Raschid, who maintained political relations with Charlemagne by means of Jewish envoys, set that monarch an example by which indeed he was not slow to profit, in actively patronising the medical college at Djondesabour, and founding a university at Bagdad. He prohibited any person from practising medicine until after a satisfactory examination before one of those faculties. In the East the theological theory of disease and of its cure was fast passing away. Of the school at Bagdad, Joshua ben Nun is said to have been the most celebrated professor, the school itself actively promoting the translation of Greek works into Arabicnot alone works of a professional, but also those of a general kind. In this manner the writings of Plato and Aristotle and promote science and literature. were secured; indeed, it is said that almost every day camels laden with volumes were entering the gates of Bagdad. To add to the supply, the Emperor Michael III. was compelled by treaty to furnish Greek books. The result of this intellectual movement could be no other than a diffusion of light. Schools arose in Bassora, Ispahan, Samarcand, Fez, Morocco, Sicily, Cordova, Seville, Granada. Through the Nestorians and the Jews the Arabs thus became acquainted with the medical science of Greece and Alexandria; but to this was added other knowledge of a more sinister kind, derived from Persia, or Intermingling of magic and perhaps remotely from Chaldee sources, the sorcery. Nestorians having important Church establishments in Mesopotamia, and the Jews having been long familiar with that country; indeed, from thence their ancestors originally came. More than once its ideas had modified their national religion. This extraneous knowledge was of an astrological or magical nature, carried into practice by incantations, amulets, charms, and talisDedication of mans. Its fundamental principle was that the planetary bodies exercise an influence over terrestrial things. As seven planets and seven supernatural. metals were at that time known-the sun, the moon, Mars, Mercury, Jupiter, Venus, Saturn, being the planets of astrology-a due allotment was made.
