728 SUMMARY OF CURRENT RESEARCHES RELATING TO 



It is intended to issuo sketches of all the month-organs of British 

 bees and other interesting insects. Such sketches will undoubtedly 

 bo of great valuo to scientific students. 



We have before had occasion to commond the practice of supplying 

 Avith slides an explanatory desertion of tho object, thus enabling tho 

 mioroBCopist to tako an intelligent interest in what he sees. We hopo 

 Mr. Enock will find an adequate reward for his enterprise. 



Francotte's Manual of Microscopical Technique.* — While thero 

 are a profusion of works in German dealing with microscopical 

 technique, the number written in cither English or French is very 

 limited, and Dr. Francotte's book will be welcomed by a considerable 

 number of practical microscopists who read French. 



The first part contains an excellent statement of the modern optical 

 theory of the Microscope— one of the best that has yet appeared — 

 with descriptions of instruments. The second part deals with fixing, 

 hardening, staining, and other reagents, and with methods of investi- 

 gation. A special feature of this part is the tables showing in a con- 

 venient analytical form the course of the various processes. The third 

 part contains a variety of practical " exercises " for the student in 

 histology, embryology, zoology, comparative anatomy, &c. Through- 

 out the book descriptions and illustrations are given of accessory appa- 

 ratus, microtomes, &c. The only unfavourable remark that we can 

 make is that some of the original illustrations are unusually rough, 

 but this, as always, is no doubt to be laid to the door of the publisher, 

 and not the author.
