Manuel de Phototypie. Par M. G. Bonnet. Post 8vo, 

 pp. X. — 146. (Paris: Gauthier-Villars et Fils. 1889.) 



Without confining himself to any particular inventor's system of mechani- 

 cal printing, the writer describes a practical process which he strongly recom- 

 mends to photographers as being in many respects superior to the usual methods 

 of multiplying photographic juoofs on silver or platinum paper. 



Le Temps du Pose. Par A. de la Baume Pluvinel. Post 8vo, 



pp. viii. — 141. (Paris : Gauthier-Villars et Fils. 1890.) 



The various factors which contribute to correct exposure are here subjected 

 to a rigid mathematical investigation, and the results embodied in a series of 

 16 tables. 



Chess Studies and End Games. By B. Hortwitz and J- 

 Kling. Second edition, revised by W. Wayte, M.A. 8vo, pp. vi. — 376. 

 (London : G. Bell and Sons. 1889.) 



The work before us is divided into two parts. Part I., Chess Studies by 

 Messrs. Hortwitz and Kling; Part II., Miscellaneous End Games by B. 

 Hortwitz. Lovers of the games will find much in this volume to instruct 

 them, and we think the student will do well to study the numerous end games 

 in which it frequently happens that more than one solution is given. It is 

 needless to add that the volume is illustrated with a very large number of 

 diagrams. 



Our Dumb Companions ; or, Conversations aboat Dogs, 

 Horses, Donkeys, and Cats. By Thomas Jackson, M.A. Sm. 4to, pp. 112. 

 (London : S. W. Partridge and Co.) Price 2s. 



This is a well-illustrated and a very interesting book for our young people. 

 It is written throughout in the form of a conversation between a father and his 

 children, aud cannot fail to interest any of our young friends who may be 

 sufficiently fortunate to possess a copy.

 don : The Author. 1889.) 



This catalogue, although prepared expressly for the convenience of the 

 author, will be found a very valuable addition to any scientific library. It is 

 divided into three sections-- 1., Serial and Periodical Publications ; II., The 

 Microscope and its Technicalities; III., The Protozoa. The work is hand- 

 somely got up ; neither labour nor expense appears to have been spared in its 

 production. 



Hazell's Annual for 1890 : A Cyclopedic Record of 

 Men and Topics of the Day. Cr. 8vo, pp. 712. (London : Hazell, Watson, 

 and Viney. 1890.) Price 3s. 6d. 



This is the fifth yearly volume of this exceedingly useful cyclopaedia, and 

 contains above 3,500 concise and explanatory articles on every topic of current, 

 political, social, biographical, and general interest referred to by the press and 

 in daily conversation. It is edited by C. D. Price, F.G.S., and we feel bound 

 to say that no efforts have been spared to make the work very valuable for 

 reference on every subject of general interest.
