The Persians possess numerous works on rhetoric, geography, medicine, mathematics, and astronomy, few of which are entitled to much consideration. In philosophy may be mentioned the "Essence of Logic," an exposition in the Arabic language of the doctrines of Aristotle on logic; and the "Moral System of Nasir," published in the thirteenth century A.D., a valuable treatise on morals, economy, and politics. 10. EDUCATION IN PERSIA.--There are established, in every town and city, schools in which the poorer children can be instructed in the rudiments of the Persian and Arabic languages. The pupil, after he has learned the alphabet, reads the Koran in Arabic; next, fables in Persian; and lastly is taught to write a beautiful hand, which is considered a great accomplishment. The Persians are fond of poetry, and the lowest artisans can read or repeat the finest passages of their most admired poets. For the education of the higher classes there are in Persia many colleges and universities where the pupils are taught grammar, the Turkish and Arabic languages, rhetoric, philosophy, and poetry. The literary men are numerous; they pursue their studies till they are entitled to the honors of the colleges; afterwards they devote themselves to copying and illuminating manuscripts. Of late many celebrated European works have been translated and published in Persia. HEBREW LITERATURE. 1. Hebrew Literature; its Divisions.--2.

HEBREW LITERATURE.--In the Hebrew literature we find expressed the national character of that ancient people who, for a period of four thousand years, through captivity, dispersion, and persecution of every kind, present the wonderful spectacle of a race preserving its nationality, its peculiarities of worship, of doctrine, and of literature. Its history reaches back to an early period of the world, its code of laws has been studied and imitated by the legislators of all ages and countries, and its literary monuments surpass in originality, poetic strength, and religious importance those of any other nation before the Christian era. The literature of the Hebrews may be divided into the four following periods:--
