Medica, and in the intelligent use of the instruments and caustics of the surgeon. In ancient Chaldea and Babylonia there were no physicians. The priesthood, as in the Middle Ages, enjoyed a monopoly of learning, which, so far as the practice of medicine was concerned, rested upon no more substantial foundation than the imposture of the charlatan. The cure of disease was effected by the exorcism of evil spirits; and such is the tenacity of venerable ideas and the lamentable credulity of the human mind that, through the influence of a certain class whose pecuniary interests are directly involved, this superstitious belief, with others equally absurd, still prevails among the members of educated communities even in our enlightened age. The difference between the fetichism of the African savage, the mediæval relic-cure, and the so-called Christian Science of modern days is one of degree and not of kind. In the infancy of civilization every malady was attributed to demoniacal possession. The Jews were the first to detect the true nature of disease and to realize the necessity for the employment of physical remedies, where heretofore, through the medium of spells and incantations, the aid of the supernatural alone had been invoked. By the adoption and application of rational principles, they revolutionized the theory and practice of medicine. Their attempts to thus partially emancipate the human mind from the degrading thraldom of superstition brought upon them the anathemas of the priesthood wherever these innovations were attempted. The wonder-workers of Pagan temples and the monkish custodians of Christian shrines saw with dismay their incomes decreasing as a consequence of the successful ministrations of the Hebrew practitioner. It was not without reason that the latter became an object of clerical animadversion, for the offerings annually bestowed by grateful credulity upon the custodians of some apocryphal relic of imaginary virtues not infrequently exceeded in value the revenues of a city. Much of the prejudice everywhere existing against the Jewish name is thus attributable to sacerdotal malevolence, originally excited by interference with material interests. But even in an age of ignorance homage was paid, however reluctantly, to the ascendency of intellectual power; and the Jews flourished in countries where the laws did not tolerate their presence and sovereigns were pledged by their coronation oaths to their destruction. Political necessity proved stronger than popular odium; and the strange anomaly of a proscribed race, whose existence was condemned by the civil and ecclesiastical codes alike, flourishing in the midst of implacable enemies was exhibited in every country of mediæval Europe. This peculiar condition was due to the dominating force of intellect alone. It is true that toleration was frequently purchased with gold; but the Jews were the sole depositaries of real knowledge, and without their
