To judge from the dedication, the authoress of this goodly duodecimo must be the daughter of Cooper, the novelist. She has much of her father’s remarkable descriptive power, but is happily deficient in that fretful discontent which disturbs the harmony of his later productions. The volume will be found a delightful companion both to the denizen of the city and country. The writer wins upon the reader’s sympathies with every page. Her intelligence is clear and quiet, enlarged by intimacy with nature and good books, and elevated by a beautiful and unobtrusive piety. We hope this will not be her last production. * * * * * _Sleep Psychologically Considered with reference to Sensation and Memory. By Blanchard Fosgate, M. D. New York: George P. Putnam. 1 vol. 12mo._ This thin volume is devoted to a subject which, though its discussion involves a consideration of topics properly metaphysical, has more general interest than any other in the science of metaphysics, because its phenomena stimulate the curiosity of all who, like Richard the Third, are troubled with dreams. The author supports, with great power of illustration and argument, three propositions, viz., that during sleep the mental faculties are as active as during wakefulness; that memory is no criterion by which to judge the mind in sleep; and that the mind is dependent upon the integrity of the organs of external sensation for a remembrance of what transpires during this state. The discussion of these topics is enlivened by many curious examples. * * * * * _Europe, Past and Present. By Francis H. Ungewitter, LL. D. New York: George P. Putnam. 1 vol. 12mo._ This is a thick volume of some seven hundred pages, completely crammed with facts relating to the history, geography, and present condition of every state in Europe. The index, containing ten thousand names, will convey an idea of the amount of matter which the author has compressed into his volume. Though a work of vast labor, we presume that its value, as a work for constant reference, will amply repay the expense of compiling it. Every man who reads European news should possess the book, provided he desires to read news intelligently. It gives accurate ideas of the relative importance of the various States, by exhibiting their financial condition as well as their territory, population, and productions. * * * * * _Chronicle of the Conquest of Grenada.
