The work of a ripe scholar, this volume is an important aid to all students of the Latin language desirous of comprehending the general doctrines of its etymology, its inflectional forms, and its syntax. It is not intended to supersede the common grammars, but to be their complement. The author is professor of the ancient languages in the University of Virginia. * * * * * _Collections of the Historical Society of Pennsylvania. No. 3. Philadelphia: John Penington._ This valuable work, in which are duly chronicled the researches of the Society, is issued in very excellent style; printed with bold, clear type, upon white, fine paper. The number before us contains, Extracts from Letters of John Quincy Adams—Letters of Thomas Jefferson—History of Moorland, by W. J. Buck—and some valuable Memoranda from the Journal of Henry M. Muhlenberg, D. D. The friends of the Society, and all interested in preserving the records of the past from oblivion, should encourage the circulation of the work. * * * * * _The Illustrated Old Saint Paul’s. By W. Harrison Ainsworth. Embellished with spirited Engravings. Philadelphia: T. B. Peterson._ Mr. Ainsworth is not a writer in whose productions we have heretofore seen any thing to admire, but the volume before us is written with much ability, and is far less exceptionable than many of his works. The era of the story is that of “The Great Plague of 1665,” and powerfully depicts the horrors of the time. There are two love scenes of marked interest interwoven with the narrative, which give it all the fascination of one of Dumas’s most powerful romances. As virtue is rewarded and vice in some degree punished, the moral of the work will meet the requirements of novel readers. * * * * * _The University Speaker: A Collection of Pieces designed for College Exercises in Declamation and Recitation. By William Russel.

The work is admirably printed, and is dedicated to Dr. James Rush of this city. * * * * * =THE AZTEC CHILDREN.= _Their probable Origin and peculiar Physical and Mental Developments; together with other Physiological Facts, connected with their History and Singular Appearance._ =BY AUSTRALIS.= The two extraordinary and interesting beings known as the “Aztec Children,” have for some considerable time been exhibited in the city of New York, where thousands with an intense and excited interest have sought to gratify their curiosity as to the probable origin and history of these wonderful representatives of ancient Adam.
