acquaintance with the motives and the affairs of humanity which resulted from its exercise, is the principal secret of the prodigious and phenomenal development of the Hebrew mind. Other considerations of no less importance contributed largely to this result. In the estimation of those who strictly observed the precepts of the law, and to whom were committed the instruction of youth and the guidance of the community, idleness was considered one of the most despicable of vices. “Whoever,” say the learned rabbis, “does not teach his son some trade, rears him for a life of brigandage;” and the sedulous inculcation of this principle led to its universal adoption and practice, until its effects are to-day discernible in the habits of every individual of Hebrew extraction. In ancient times there was no industrial occupation whose requirements were unfamiliar to the Jewish artisan, no profession in which the scholars of that nation did not excel. The talents of the latter were often unprofitably employed in commentaries on the Talmud and whimsical interpretations of the Scriptures, whose texts were at times distorted to support some absurd and extravagant conception which the fruitless ingenuity of the doctors of the law, devoted to metaphysical subtleties, had invented. The Talmud was regarded with even greater reverence than the Pentateuch. Its diligent perusal was required as a duty; children were familiar with its maxims long before their minds were sufficiently developed to thoroughly comprehend them; and the mastery of this voluminous and incongruous compilation was regarded as the rarest and most desirable of mental accomplishments. From the study of this work was derived the partiality for mysticism, magic, and oneiromancy, topics which formed so large a proportion of ancient Hebrew literature, and which frequently dissipated the efforts of genius which might have been exercised in more practical and advantageous employments. In the Talmud, however, are also to be found the germs of medical science in which, from the remotest antiquity, the Jews were distinguished, and whose pursuit, thus sanctioned by an authority regarded as divine, became the favorite pursuit of that extraordinary people. Some of its ideas and principles had been learned from the Magi of Persia; others were borrowed from the Egyptian priesthood. The more numerous, and by far the most valuable, precepts of that science, however, were a portion of the inheritance transmitted by the noble school of the Ptolemies. With all were mingled not a few puerile superstitions which exalted the virtues of charms and amulets. The Bible gives many instances of diseases and their treatment, which in that age was the peculiar province of the Levites. The talents of the Hebrew thus early directed to medicine and botany arrived eventually at an extraordinary degree of development; and his adaptive ingenuity was revealed in the discovery and application of many indispensable drugs of the Materia
