MESSRS. TRÜBNER & CO. beg to call attention to their _ORIENTAL SERIES_, in which will be collected, as far as possible, all extant information and research upon the _History, Religions, Languages, Literature, &c., of Ancient India, China, and the East_ in general. The ORIENTAL SERIES will be on a comprehensive design, and no labour or expense will be spared to render the undertaking worthy of its subject. Messrs. TRÜBNER & CO. have already secured the services of eminent Eastern students and writers; and while the labour proposed must necessarily prove vast, they intend to accomplish it by working with many able hands over the whole field, under careful and well-organised Editorship. _THE FOLLOWING WORKS ARE NOW READY_:-- Second Edition, post 8vo, cloth, pp. xvi.--427, price 16s. ESSAYS ON THE SACRED LANGUAGE, WRITINGS, AND RELIGION OF THE PARSIS. BY MARTIN HAUG, PH.D., Late of the Universities of Tübingen, Göttingen, and Bonn; Superintendent of Sanskrit Studies, and Professor of Sanskrit in the Poona College; Honorary Member of the Bombay Branch Royal Asiatic Society, &c. EDITED BY DR. E. W. WEST. I. History of the Researches into the Sacred Writings and Religion of the Parsis, from the Earliest Times down to the Present. II. Languages of the Parsi Scriptures. III. The Zend-Avesta, or the Scripture of the Parsis. IV. The Zoroastrian Religion, as to its Origin and Development. The Author of these Essays intended, after his return from India, to expand them into a comprehensive work on the Zoroastrian religion; but this design, postponed from time to time, was finally frustrated by his untimely death. That he was not spared to publish all his varied knowledge on this subject must remain for ever a matter of regret to the student of Iranian antiquities. In other hands, the changes that could be introduced into this Second Edition were obviously limited to such additions and alterations as the lapse of time and the progress of Zoroastrian studies have rendered necessary. In the First Essay, the history of the European researches has been extended to the present time; but for the sake of brevity several writings have been passed over unnoticed, among the more valuable of which those of Professor Hübschmann may be specially mentioned. Some account has also been given of the progress of Zoroastrian studies among the Parsis themselves. In the Second Essay, additional information has been given about the Pahlavi language and literature; but the technical portion of the Avesta Grammar has been reserved for separate publication, being better adapted for students than for the general reader.
