threefold basis of their theory and practice. A superstitious reverence for the dead confined both the Greeks and the Arabians to the dissection of apes and quadrupeds; the more solid and visible parts were known in the time of Galen, and the finer scrutiny of the human frame was reserved for the microscope and the injections of modern artists. Botany is an active science, and the discoveries of the torrid zone might enrich the herbal of Dioscorides with two thousand plants. Some traditionary knowledge might be secreted in the temples and monasteries of Egypt; much useful experience had been acquired in the practice of arts and manufactures; but the _science_ of chemistry owes its origin and improvement to the industry of the Saracens. They first invented and named the alembic for the purposes of distillation, analyzed the substances of the three kingdoms of nature, tried the distinction and affinities of alcalis and acids, and converted the poisonous minerals into soft and salutary medicines. But the most eager search of Arabian chemistry was the transmutation of metals, and the elixir of immortal health: the reason and the fortunes of thousands were evaporated in the crucibles of alchemy, and the consummation of the great work was promoted by the worthy aid of mystery, fable, and superstition. But the Moslems deprived themselves of the principal benefits of a familiar intercourse with Greece and Rome, the knowledge of antiquity, the purity of taste, and the freedom of thought. Confident in the riches of their native tongue, the Arabians disdained the study of any foreign idiom. The Greek interpreters were chosen among their Christian subjects; they formed their translations, sometimes on the original text, more frequently perhaps on a Syriac version; and in the crowd of astronomers and physicians, there is no example of a poet, an orator, or even an historian, being taught to speak the language of the Saracens. The mythology of Homer would have provoked the abhorrence of those stern fanatics: they possessed in lazy ignorance the colonies of the Macedonians, and the provinces of Carthage and Rome: the heroes of Plutarch and Livy were buried in oblivion; and the history of the world before Mahomet was reduced to a short legend of the patriarchs, the prophets, and the Persian kings. Our education in the Greek and Latin schools may have fixed in our minds a standard of exclusive taste; and I am not forward to condemn the literature and judgment of nations, of whose language I am ignorant. Yet I _know_ that the classics have much to teach, and I _believe_ that the Orientals have much to learn; the temperate dignity of style, the graceful proportions of art, the forms of visible and intellectual beauty, the just delineation of character and passion, the rhetoric of narrative and argument, the regular fabric of epic and dramatic poetry. The influence of truth and reason is of a less ambiguous complexion. The philosophers of Athens and Rome enjoyed
