422 space, and has done it in a clear style and a very satisfactory manner. The book is intended as a reading book for boys and girls in school, to whose tastes and capacity it seems well adapted; but the author will be pleased if it also interests older readers, and hopes it may enlarge their sympathy with our native Americans. Besides the accounts of the tribal divisions, general customs, manner of life, houses, and institutions—which when they are counted up are found to be quite numerous—it has articles on the sign language, medicine men and secret societies, the mounds and their builders, George Catlin and his work, the cliff-dwellings and ruins of the Southwest, the tribes of the Northwest coast, matters of religious and mythological significance, the Aztecs, the Mayas, and the ruined cities of Yucatan and Central America.

The revision, for the fifth edition, of H. Newell Martin's The Human Body (Henry Holt & Co., New York, $1.20) was undertaken by Prof. George Wills Fitz with the idea of bringing the book into accord with the late developments of physiology, of simplifying the treatment of some parts while expanding that of others, and of giving additional illustrations. Every effort has been made to avoid injuring those features of the author's work which have contributed to making the book so favorably known. The changes in the first nine chapters are largely verbal; but considerable alterations and additions have been made in some of the succeeding chapters. The directions for demonstrations and experiments have been greatly enlarged and collected into an appendix. They include the new requirements in anatomy, physiology, and hygiene for admission to Harvard College and the Lawrence Scientific School.

We have already noticed some of Lucy S. W. Wilson's excellent Manuals on Nature Study, particularly the one intended for the guidance of teachers. We now have in the same line the First Reader of a series on Nature Study in Elementary Schools (New York: The Macmillan Company, 35. cents), a book composed of original matter and selections which has been prepared "with the desire of putting into the hands of little children literature which shall have for their minds the same interest and value that really good books have for grown-up people." But the author does not expect to accomplish this by merely giving the book to the child and leaving the reading to work out its own effect. Each of the lessons is intended to be preceded by a Nature lesson. During or after the reading a lesson should be given in the new words introduced, and afterward the lessons should be grasped for the sake of thought. The lessons, which have appropriate illustrations from Nature, present some novel features. Among them is an apparent intention in the original compositions to follow the child's method of thought.

The American Elementary Arithmetic (American Book Company) is intended by the author, Prof. M. A. Bailey, to cover the first five years' work (beginning apparently very young) in the study, and is the first of a two-book series. It is divided into two parts—for the primary and for the three succeeding grades. It contemplates the use of apparatus, consisting of paper, paste-board, toy money, blocks, and splints. The attempt is made to give every subject twice: first in pictures, and second in the particular form of printed words. Mathematical conceptions are presented in the first chapter in the order in which they are supposed to arise in the child's consciousness—first, once or more, indefinitely; next, how many, by holding up fingers, laying down sticks, etc.; and then by words, and so on—all introductory work designed to develop step by step a mathematical vocabulary, and to form a habit of clear mathematical thinking. The laboratory plan is followed in the succeeding chapters.

In the Language Lessons of J. G. Park (American Book Company) an arrangement of the matter is aimed at which will draw upon the student for such effort as may be expected at a given stage of advancement, which will cause him to think first and then to express his thought with clearness and precision. In the succeeding parts are given exercises on language work, with special drills upon capitalization and punctuation, inductive lessons in grammar, and, finally, lessons so graded that a student may advance very readily from them into the higher work of grammar. The
