Rh knowledge are not of great use in classification. The main part of the book is the account of the structure of the different groups of birds, which is treated of to a considerable extent; and a large number of facts, some of which are recorded for the first time, are incorporated in the systematic part of the book. While all the principal facts pertaining to the subject are believed to have been given, and nothing of importance to have been left out, references are made in each section to most of the memoirs already published. The majority of the facts of bird structure have been verified by the author, especially those relating to osteology and anatomy, and he has drawn liberally on the notebooks of his two predecessors. The book gives first an account of the general structure of birds; next of the reproductive and renal organs, the circulatory, respiratory, and muscular systems, osteology, brain and nervous system, and affinities of birds, and, finally, the classification.

Bush Fruits is the first of a proposed series of monographs on the various types of American fruits, to be published under the editorial direction of Prof. L. H. Bailey. Its purpose is to present both the practical and the technical phases of all the important questions concerned in the cultivation and domestication of the fruits that grow on bushes; and the attempt is made to present these two sides separate from the details of history, botany, and entomology, so that the practical reader may be introduced at once to the information he is seeking. The aim is made to treat general truths and principles rather than mere details of practice, leaving the reader to think out and solve the local problems for himself. The author, Mr. F. W. Card, who presented the work originally as a Cornell University thesis, was first a bush-grower, and then a student and teacher, acquiring first the practice and then the theory. The fruits treated of are raspberries, blackberries, dewberries, currants, gooseberries, buffalo berry, gounie, huckleberries, Juneberries, the cranberry, barberry, and sand cherry—all, as to their important types, except the currants, evolutions from the species of our own woods. A useful list of American books on bush fruits is given in the appendix.

The History of the World, from the Earliest Historical Time to the Year 1898, is the latest addition to the Concise Knowledge Library, "a series of volumes on great subjects, containing in an abridged form a wealth of exact information which can be thoroughly relied upon by the student, and yet of such a popular character as to meet the needs of the general reader." This compact volume of 790 pages presents a complete survey of the world's history. After a brief introduction describing the various races that have furthered civilization, ancient history proper begins with the Egyptians, the people of whom we possess the earliest records, and who were the first to emerge out of the darkness of prehistoric times. Closely connected with them, both by racial affinities and political ties, were the other great empires in the southwestern part of Asia that one after the other rose, flourished, and fell into decay. The interesting part of the book here is the constant reference to the familiar facts of the Bible, the connection of the known with the unknown. The rise and development of Greece and Rome, following in due course, bring us down to the middle ages. Mediæval history has for its stage Europe, and for its argument the upbuilding of the states on which our modern political institutions rest. Modern history, dating from the discovery of America, then turns the eyes of the nations westward, to found empires beyond the sea. Nor is the East forgotten. Asia, the cradle of man, and Africa, where he first rose into consciousness of himself and recorded his deeds, again claim the historian's attention. But now it is China and Japan on the one continent, and the conquests and colonies of the Europeans on the other. Neither is the country youngest in civilization,
