Handbook of Photomicrography. By H. Lloyd Hind, B.Sc, 

 F.I.C., and W. Brough Randies, B.Sc. 8| x 5 j in., xii + 

 292 pages, 44 plates and 71 text illustrations. London, 

 1913 : G. Rout ledge & Sons, Ltd. Price 7s. 6d. net. 



The student of photomicrography, whether he approach the 

 subject from the side of photography or microscopy, can hardly 

 complain of the lack of manuals whose aim is to guide him 

 in this fascinating subject. The photographer, in reading 

 Messrs. Hind and Randies' handbook, may perhaps be surprised 

 that so much space is devoted to details concerning the micro- 

 scope and its accessories; but he must remember that in order 

 to photograph an object under the microscope it is very essential 

 he should possess the necessary knowledge of the instrument 

 to obtain the best results visually. 



Although the subject is treated by the authors in an ele- 

 mentary manner, at the same time, however, the processes are 

 discussed in sufficient detail to be of use in research. A special 

 feature of the book is the very numerous illustrations, and with 

 each photomicrograph reproduced full details are given of the 

 process and apparatus used and the method of developing the 

 negative. This very useful feature enables any special worker 

 to select the best means for his own branch of the subject, 

 whether it be the photography of the minute details of diatoms, 

 the stained sections for use in the histology of plants and 

 animals, or rock sections and crystals under polarised light. 

 The subject of colour photomicrography is dealt with in 

 Chapter XIII. The utility of the Autochrome and Paget plates 

 for registering the appearance of thin rock sections under 

 polarised light was excellently demonstrated at a recent meeting 

 of The Photomicrographic Society. 



The subject of cinema-micrography is referred to, but this 

 could hardly be dealt with fully in an elementary textbook. 

 In fact, as a means of research it is in its infancy, but fruitful 

 results may be expected in the future in the study of the 

 life-history and movements of micro-organisms. 



There are useful formulae and tables at the end of the book 

 and an index. Both authors and publishers may be congratu- 

 lated on the appearance of the book.
