would be impeded in the great pursuits of experimental philosophy, in which he chiefly delights, he neglects all honor and wealth, though he might, when he wished, enrich himself by his knowledge." * * * * * _Popular Music of the Olden Time_. A Collection of Ancient Songs, Ballads, and Dance-Tunes, Illustrative of the National Music of England. With Short Introductions to the Different Reigns, and Notices of the Airs from Writers of the Sixteenth and Seventeenth Centuries. Also, a Short Account of the Minstrels. By W. Chappel, F.S.A. The whole of the Airs harmonized by G. A. McFarren. 2 vols. pp. 384, 439. London: Cramer, Beale, & Chappell. New York: Webb & Allen. In tracing the history of the English nation, no line of investigation is more interesting, or shows more clearly the progress of civilization, than the study of its early poetry and music. Sung alike in the royal palaces and in the cottages and highways of the nation, the ballads and songs reflect most accurately the manners and customs, and not a little of the history of the people; while, as indicating the progress of intellectual culture, the successive changes in language, and the steady advance of the science of music, and of its handmaid, poetry, they possess a value peculiarly their own. The industry and learning of Percy, Warton, and Ritson have rendered a thorough acquaintance with early English poetry comparatively easy; while in the work whose comprehensive title heads this article the research of Chappell presents to us all that is valuable of the "Popular Music of the Olden Time," enriched by interesting incidents and historical facts which render the volumes equally interesting to the general reader and to the student in music. Chappell published his collection of "National English Airs" about twenty years ago. Since that time, he tells us in his preface, the increase of material has been so great, that it has been advisable to rewrite the entire work, and to change the title, so that the present edition has all the freshness of a new publication, and contains more than one hundred and fifty additional airs.
