since the nerve fibres are rendered very easily distinguishable. For nerve endings 

 the gold stain of Lowit was used. Miiller's fluid, and occasionally sublimate, 

 were the best fixatives. Embryonic and small animals were decalcified with 

 picric or hydrochloric acid. Imbedding was sometimes in collodion and some- 

 times in paraffin. Staining was mostly in haematoxylin and eosin. Both bulk 

 and section staining were used. a. m. c.

berlah, assistants in the Royal Botan- 

 ical Gardens at Halle, Germany. The present work is a very decided advance 

 upon previous editions, the revision having been most thorough and painstaking. 

 The authors have endeavored to include only those forms which are most com- 

 mon and most widely distributed. Many genera and species described in recent 

 years have been added in this edition. The cosmopolitan character of the 

 organisms found in fresh water makes a treatise of this nature useful everywhere, 

 quite as much in America as in Europe. The scope of the book is indicated in 

 the title. The groups included are the bacteria, alga;, desmids and diatoms, 

 the protozoa and the rotifers. The main body of the text is made up of brief 

 diagnostic descriptions with synoptic keys to the various divisions down to 

 species, over OOO of which are figured on the plates. The specific descriptions 

 are necessarily very brief. The book is thus not for the use of the specialist, 

 but is intended for the general student, and the amateur microscopist. It is a 

 very convenient manual for the biological laboratory. c. a. k.
