The interest expressed by our readers in Zoological methods, both in the 

 laboratory and in the field, has made it necessary to add to our reviews a depart- 

 ment of " Current Zoological Literature." In this department will be included 

 reviews of important zoological investigations, especially those which deal with 

 types most frequently used in laboratory work; methods in use in zoological 

 laboratories and by zoological investigators in the preservation and preparation 

 of animal forms for microscopical examination, for dissection and for exhibition 

 purposes ; methods in field work in zoology, apparatus for collecting aquatic and 

 marine life, and suggestions for maintaining aquaria and vivaria in the labora- 

 tory ; notes on methods in vogue at fresh water and marine biological stations. 

 The fact that Mr. C. A. Kofoid, University of California, will conduct this 

 department, is in itself a guarantee of the practical nature of the matter, which 

 will be selected from the mass of American and foreign literature on the subject, 

 and of the faithful rendering of the author's meaning. Separates of papers or 

 books for review should be sent addressed to C. A. Kofoid, University of Cali- 

 fornia, Berkeley, Cal. Authors will confer a favor by sending separates as 

 soon as issued, in order that our reviews may be as little delayed as possible. 



Now that we are on time in publication once more, notes and news items 

 from the various laboratories will be welcomed, and we ask those in need of 

 assistance to make use of the question-box. Inquiries will be answered through 

 the Journal, or, if in pressing need of information, at once by letter.

Numerous requests for an exchange department for the exchange or sale of 

 books, material, and apparatus, have reached the editor from time to time. We 

 do not consider the conduct of such a department advisable, as we are not in 

 position to know the responsibility of every sender of an exchange notice, or of 

 the merits of the article offered.
