Physical Arithmetic. By A. Macfarlane, M.A., D.Sc, 



F.R.S.E., Examiner in Mathematics in the Universities of Edinburgh ; pp. 

 IX. — 357. (London : Macmillan and Co., 1885.) 



This is a treatise on apphed arithmetic, the applications being chiefly in 

 physical sciences. The Author tells us that "Knowledge of the elements of 

 pure arithmetic is assumed, but that the more advanced methods are explained 

 when their application happens to occur." 



The examples have been partly selected from recent examination papers 

 of the several universities, ancl partly prepared by the Author. The work is 

 divided into the following sections : — Financial, Geometrical, Kinematical, 

 Dynamical, Thermal, Electrical, Acoustical, Optical, and Chemical. 



Looking at the examples from a student's point of view, we should have 

 liked to have seen the sign . •. (therefore) oftener used in the examples. 



Young Folks' Ideas. A Story : by Uncle Laurence, Author 

 of Young Folks' Whys and Wherefores, etc., pp. 243. (Philadelphia : Lippin- 

 cott and Co., 1885.) 



We have here the merest outline of a story into which a good deal of 

 Scientific and Technical Knowledge is interwoven. The subjects varying from 

 Bread-making, Gold and Silver, Gas, and Printing, to Wine, and even Will- 

 making. The young folks to whom we are introduced are certainly the most 

 precocious it has ever been our fortune to meet. The " get-up " of book is 

 everything that can be desired. 



Geology and the Deluge. By the Duke of Argyle ; pp. 47. 



(Glasgow : Wilson and McCormick, 1885.) 



This is a lecture delivered by the Duke of Argyle at Glasgow. His Grace 

 veiy conclusively proves the occurrence of a Deluge of comparatively recent 

 date, but whether this was the same that drowned the world in the days of 

 Noah is we think not so satisfactorily proved ; four thousand years of Geologic 

 time being but a very insignificant portion. We feel sure our friends will be 

 glad to read this very clever address. 



Comparative Physiology and Psychology. A discussion 



of the Evolution and Relations of the mind and body of man and animals. 

 By S. V. Clevenger, M.D., pp. VI. — 257. (Chicago : Jansen, McClurg, and 

 Co., 1885.) 



A cleverly w^ritten book, the object of the author being to elaborate as far 

 as possible, a practical mental science which will reconcile the observations of 

 Anatomists, Psychologists, and Pathologists, with direct reference to the more 

 intelligent treatment of insanity. The work is divided into fifteen chapters, 

 and exhibits a vast amount of thought and research on the part of the Author. 



British Butterflies, Moths, and Beetles. By W. F. Kirby; 



pp. 96. (London: W. Swan Sonnenschein and Co., 1885.) 



A capital little shilling book for the Young Collector. It is divided into 

 three portions, the first of which treats of the order of Insects generally, with 

 their division into orders, etc. ; the next is devoted to British Beetles, and on 

 the part played ])y them in the Economy of Nature ; the third to British But- 

 terflies and Moths. The book is illustrated with several plates and a 

 number of wood engravings.
