LITERARY NOTICES.

(United States National Museum), Dr. Charlex 

 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 un- 

 tenable claims that have been made in its 

 favor, an application of the principles dis- 

 cussed 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. 



JIow to Build Dynamo- Electric Machin- 

 ery, by Edicard Trevert, is intended to be a 

 practical treatise, and in no way to be consid- 

 ered 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 read- 

 er to understand the text more clearly. The 

 machines described have been carefully se- 

 lected for efficiency and beauty of form and 

 as being easy to build. Chapters on com- 

 mercial dynamos and motors are added to 

 show the general construction of large ma- 

 chines ; and chapters on management, arma- 

 ture winding, and field-magnet winding, and 

 a chapter of useful tables are inserted. The 

 machines described are all American. (Pub- 

 lished by the Bubier Publishing Company,

In Hydraidic Power and Hydraulic Ma- 

 chinery (J. B. Lippincott Co., American pub- 

 lishers) Henry Robinson has drawn from his 

 own practice and utilized the experience of 

 others, as reported in the proceedings of va- 

 rious professional societies, to record, in a 

 form convenient for reference, existing expe- 

 rience 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 en- 

 larging and improving it. The present, sec- 

 ond, edition is the outcome of this desire and 

 contains much new matter, with better treat- 

 ment of the old. Some compression, both of 



subjects and of descriptions, has been neces- 

 sary to accomplish this, but the author thmks 

 the illustrations selected of the innumerable 

 applications of hydraulic power will be con- 

 sidered faii'ly to meet the circumstances.
