LITERARY NOTICES.

(United States National Museum), Dr. Charles A. White had in view, among several objects, a further presentation of elementary matter pertaining to biological geology than has heretofore been published, the defense of biology as an indispensable aid in geological investigation, the repudiation of certain untenable claims that have been made in its favor, an application of the principles discussed to the practical work of the geologist, and the demonstration of the necessity of the preservation of fossil remains in public museums as storehouses of evidence upon geological questions.

How to Build Dynamo-Electric Machinery, by Edward Trevert, is intended to be a practical treatise, and in no way to be considered technical. Some theory, however, is given to help the reader in a general way. Its purpose is to give directions for building small dynamos and motors, accompanied by working drawings which will enable the reader to understand the text more clearly. The machines described have been carefully selected for efficiency and beauty of form and as being easy to build. Chapters on commercial dynamos and motors are added to show the general construction of large machines; and chapters on management, armature winding, and field-magnet winding, and a chapter of useful tables are inserted. The machines described are all American. (Published by the Bubier Publishing Company, Lynn, Mass. Price, $2.50.)

In Hydraulic Power and Hydraulic Machinery (J. B. Lippincott Co., American publishers) Henry Robinson has drawn from his own practice and utilized the experience of others, as reported in the proceedings of various professional societies, to record, in a form convenient for reference, existing experience in the engineering of water-pressure machinery. Special attention is given to the subject of the flow of water under pressure and to the employment of water-pressure mains to transmit power through the streets of a town on the principle which the author terms "power co-operation." Since the first edition was published, in 1886, the author has had constantly in view the desirability of enlarging and improving it. The present, second, edition is the outcome of this desire and contains much new matter, with better treatment of the old. Some compression, both of subjects and of descriptions, has been necessary to accomplish this, but the author thinks the illustrations selected of the innumerable applications of hydraulic power will be considered fairly to meet the circumstances.
