notion of the volume's contents. It contains hardly a 

 page that is superfluous and none that is uninteresting. 

 The new edition is now a book of first importance. On 

 subjects like the applications of thermodynamics to 

 chemistry, chemical equilibrium, electromotive force, and 

 others in which Dr. Nernst has been a pioneer, it con- 

 tains the best descriptions in English. The worst one 

 might say of it is that occasionally the author is uncritical 

 in compiling those parts of the subjects in which he is 

 not particularly interested. But this book is read for 

 Nernst's own work and all of that is excellently put. 



The new edition contains rewTitten chapters on radio- 

 activity and on the theory of the solid state, and many 

 of the other sections have been revised and added to, 

 in order to bring them abreast of the work that has been 

 done since the last edition, published seven years ago.

Colour and Methods of Colour Reproduction. By Dr. L. C. 

 Martin. With chapters on Colour Printing and 

 Colour Photography by \Vili.i.\m Gamble. (Blackie 

 & Sons, Ltd., 125. 6d.) 

 This important book should be read by all those who 

 are interested in colour. It gives an accurate and well- 

 balanced account of the whole matter, and in a form 

 that can be understood by those who are not expert 

 mathematicians or great students of physics. The first 

 part of the book aims at giving a simple account of the 

 nature of light, colour analysis, and synthesis, the colours 

 of material objects, colour in regard to illumination, 

 colour in human experience, and colouring materials. 

 The second part is definitely more technical, and deals 

 with the eye and its reactions to light, instruments for 

 colour measurement, colour vision, and colour blindness. 

 The third part, contributed by the editor of The Pro- 

 cess Year Book, deals with colour printing and colour 

 photography. The book is well illustrated and well 

 produced. If all books on special subjects could be 

 written and produced like this one there would not be 

 much money spent on encyclopEedias. A. S. R. 



Ductless and Other Glands. By Professor Fred E. 



Wynne, B.A.M.B., D.Ph., etc. (George Allen & 



Unwin, Ltd., 4s. 6rf.) 



A most refreshing work on a subject on which much 



has been written — much that is learned, much that is 



" popular," and very much that is sheer insanity. This 



book is in the best sense of the word popular. It is 



written in most readable style, begins at the beginning, 



takes nothing for granted, yet tells all that is established 



as regards the work of these strange and potent, yet much 



libelled laboratories of the human body. R. J. V. P. 



Practical Bacteriology for Chemical Students. By David 

 Ellis, Ph.D., D.Sc, F.R.S.E. (Longmans, Green 

 & Co., 45. 6d. net.) 

 This is a really admirable and thoroughly practical 

 handbook, which will suit the requirements of that 

 increasingly large number of students to whom a know- 

 ledge of bacteriology is important. It bears the mark 

 of long acquaintance with the difficulties of beginners in 



dealing with the delicate technique and numerous pitfalls 

 of the science. Any student who carefully follows the 

 full and well-illustrated descriptions of the methods 

 employed to identify bacteria will be soundly equipped 

 for a fuller study of this wide and fascinating subject.
