I HE QUARTERLY REVIEW OF BIOLOGY proposes to publish the results of 

 recent studies in the several fields of Biology in accurate and interesting form. 

 The papers published will present the current status of the various phases of 

 Biology: Anatomy, Anthropology, Behavior and Comparative Psychology, 

 Botany, Cytology, Ecology, Embryology, Experimental Morphology, 

 General Physiology, Genetics, Geographical Distribution and Taxonomy, and Zoology. 

 The articles will be short but comprehensive, written so far as possible in non-technical 

 language, so that teachers, investigators, and other persons who are not actively engaged in 

 research but who are interested in Biology in its broader sense, can readily understand papers 

 by specialists working in other fields. 



Since technical language will be used sparingly, but as extensively as is necessary to secure 

 accuracy of statement, the Quarterly Review of Biology should have a wide appeal. Teach- 

 ers of biology in the secondary colleges and high schools should find it of timely value in their 

 work. It is planned to be interesting, readable, and entertaining — a journal of broad informa- 

 tion in the several fields of Biology. 



The subjects and authors of all articles published will be selected by the Editors and the 

 Advisory Board. This procedure assures readers of accurate and timely articles. 



A feature of the REVIEW will be the section dealing with New Biological Books. In this 

 department the book literature of different countries in the field of Biology will be given prompt 

 notice. 



Each number of the Quarterly Review of Biology will consist of about 150 pages, two 

 columns to the page. 



The Quarterly Review of Biology will be issued in March, June, September and 

 December.
