He has, as we must admit, one qualification for attaining his object, in being completely master of his subject, and in knowing also how to treat it in an attractive manner.--FELIX LIEBRECHT, in _Academy_ (London). It is extremely interesting for its happy combination of psychologic analysis with a study of the primitive beliefs of mankind.... A perusal of this thorough work cannot be too strongly recommended to all who are interested in comparative mythology.--_Revue Critique_ (Paris). Mr. Fiske is a master of perspicuous explanation.--_World_ (New York). Its weight of sense and its lucidity will extend Mr. Fiske's reputation as one of the clearest-minded, most conscientiously laborious and well-trained students in this country.--_Nation_ (New York). With the capacity for profound research and the power of critical consideration, he has a singular grace of style, and an art of clear and simple statement, which will not let the most indifferent refuse knowledge of the topics treated. In such a field as the discussion of old fables and superstitions affords, we have not only to admire Mr. Fiske for the charm of his manner, but for the justice and honesty of his method.--_Atlantic Monthly._ It is both an amusing and instructive book, evincing large research, and giving its results in a lucid and attractive style.--E. P. WHIPPLE. * * * * * =THE UNSEEN WORLD, AND OTHER ESSAYS.= 12mo, pp. 349, $2.00. CONTENTS: The Unseen World; The To-morrow of Death; The Jesus of History; The Christ of Dogma; A Word about Miracles; Draper on Science and Religion; Nathan the Wise; Historical Difficulties; The Famine of 1770 in Bengal; Spain and the Netherlands; Longfellow's Dante; Paine's St. Peter; A Philosophy of Art; Athenian and American Life. We think every one will remark, while examining this volume, the variety of subjects treated; and if anybody has formed an opinion that Mr. Fiske is a man who cares for nothing but myths and philosophy, he will find occasion to correct it. Many of these papers are critical reviews of important books widely different in their subjects; but to each study the writer seems to have brought, besides an excellent quality of discriminating judgment, full and fresh special knowledge, that enables him to supply much information on the subject, whatever it may be, that is not to be found in the volume he is noticing. To the knowledge, analytical power, and faculty of clear statement, that appear in all these papers, Mr. Fiske adds a just independence of thought that conciliates respectful consideration of his views, even when they are most at variance with the commonly accepted ones.--_Boston Advertiser._
