This is a sensible book, and presents some important features in striking contrast with other Primary Geographies.

Its DEFINITIONS are illustrated on the true method of "object teaching,”— first showing and describing the object, then giving the name.

WATSON'S HAND-BOOK

OF

CALISTHENICS AND GYMNASTICS.

BY J. MADISON WATSON.

8vo. Cloth, $1.60.

PART FIRST of this volume, under the head of Vocal Gymnastics, embraces thorough and practical articles on Respiration and Phonetics, a masterly treatise on Elocution, and Recitations in Verse. PART SECOND, the most extended and varied course of exercises in Calisthenics ever published. PART THIRD, an exhaustive course of exercises in Gymnastics, with wands, dumb-bells, Indian clubs, and hand-rings.

This is the only gymnastic drill-book, with words of command, and classes of movements, systematically arranged, in any language. It is the first work that seizes the theories of educators and philanthropists, "the forms of things unknown," and "turns them into shapes." In a word, it presents, in a simple and well-defined form, the means of rendering physical culture easy and certain to the rich and the poor, to persons of all ages, either individually or in classes.

Exercises for the lungs, the voice, the organs of speech, the joints, and all the muscles, are strictly classified, involving a prescribed number of positions and elementary movements, with an almost innumerable variety of combinations. These movements are executed simultaneously by several persons, in exact time, in connection with counting, phonetics, recitations, or music, either vocal or instrumental, thus insuring geniality, and generous emulation alike in the school, the family, and the gymnasium.

NINETEEN PIECES OF APPROPRIATE PIANOFORTE MUSIC Are introduced. Those not composed expressly for this work are selected and arranged, from the choicest productions of the ablest masters, by the well known and eminent musicians and composers

G. F. BRISTOW AND H. B. DODWORTH.

The wood cuts are more numerous and better executed than those of any corresponding work, either gymnastic or military. They are from original designs, illustrating positions actually taken, and movements executed by the author. It is printed on fine and heavy tinted paper. The typography is anrivaled.

This book is already adopted by the Board of Education of New York City.
