THE following Essay has already been printed, by way of Commentary on a Collection of Eastern Poems, to which it is added; but, as it contains many remarks on the manners of the Asiaticks, it seemed proper to be inserted in this Volume, after the Life of Nader Shah: it will be found very different, both in form and style, from the Treatise, which the Author wrote in French on the same subject, and published in 1770, with his Translation of the King of Denmark’s Persian Manuscript. Both these Dissertations were intended only as introductory to a much larger work, on the Asiatick Poetry, written in Latin for the convenience of learned foreigners, and entitled, Poeseos Asiaticæ Commentarii, which will be offered to the publick in the middle of next March.
