A Practical Arithmetic. By G. A. Wentworth, A.M., 



and Rev. Thos. Hill, D.D., LL.D. For High Schools and Academies. 

 Crown 8vo, pp. xvi. — 351. (Boston : Ginn and Co. 1885.) 



This is a very useful book ; the method of teaching is in some cases slightly 

 different from that to which we have been accustomed. We notice that 

 decimal fractions are introduced at the beginning of the book ; this is doubtless 

 owing to the American currency. They are more fully explained at a later 

 period. Many of the rules are quite new to us, and very practical. 



Elements of Inorganic Chemistry : Descriptive and 



Qualitative. By James H. Shepard, Instructor in Chemistry, Ypsilanti High 

 School ; crown 8vo, pp. xix. — 377. (London : G. F. Putnams and Sons, 27, 

 King William Street, Strand. Boston, U.S.A. : D. C. Heath and Co. 1885.) 



This in the hands of an efficient teacher will prove a very useful book for 

 junior pupils who have facilities for practical work in a good laboratory. 



We notice the author coins the word " chemism " as a substitute for our 

 more general, and we think preferable term, " Chemical affinity; " the word 

 "valence" is also used for "valency." The book is nicely got up, and has 

 about 20 illustrations. 



The Human Body and its Structure, with Hints on Health. 



A Practical Treatise on the Design, Nature, and Functions of the various parts 

 of the Human Frame. Post 8vo, pp. viii. — 175. (London : Ward, Lock, and 

 Co.) Price is. 



The design of this book is to give a practical treatise on the nature and 

 construction of the human body, exemplifying its structure, the philosophy of 

 the various organs, tissues, bones, muscles, etc. ; it contains in a popular form 

 many of the principles of anatomy and physiology ; it is well illustrated with 

 86 wood engravings. 



Illustrated Lectures on Ambulance Work. By R. 



Lawton Roberts, M.D. Post 8vo, pp. xiv. — 171. Price . (London : 

 H. K. Lewis. 1885.) 



These lectures were originally delivered to Ambulance Classes, held in 

 connection with the Winnstay and other Collieries to members, who consisted 

 chiefly of colliers, furnace-men, fitters, carpenters, &c., and who displayed 

 remarkable aptitude in the pursuit of their studies. 



The lectures embrace all the points laid down in the Syllabus of Instruc- 

 tion issued by the St. John's Ambulance Association, are very pleasantly written, 

 and exceedingly well illustrated. The book is nicely got up. 



Diet for the Sick : A Treatise on the value of Foods, their 



application to special conditions of Health and Disease, and on the best 

 methods of their preparation. By Mrs. Mary F. Henderson. Crown 8vo, 

 pp. ix. — 234. (New York : Harper Bros. 1885.) 



The author tells us " A proper dietary is surely as essential to the recovery 

 of an invalid as medicine ; and yet it will be observed that medical works 

 give a thousand pages to medical therapeutics to one of dietaries." 



The work before us gives us some remarks about Beverages and Foods ; 

 New Health Foods ; Artificial Digestion by means of Pancreatic Ferments ; 

 Grape Juice ; Diet in Different Diseases, &c. ; Receipts for the Sick and 

 Convalescent, &c., &c. It will be found useful in the Sick-room.
