Explanatory Note 



The items contained in the Chronological Bibliography are ar- 

 ranged alphabetically by authors. Each item consists of (1) the 

 name(s) of the author (s) ; (2) the titles of the articles or books; 



(3) the abbreviations of the titles of the original references; and 



(4) the abbreviations of the titles of the abstracting journals. 

 When the titles of articles written in foreign languages have not 



been translated by the abstracting journals, the authors have 

 translated them in order to give the references greater value. 

 Quotation marks enclose untranslated idioms. Because of the un- 

 availability of certain source materials, there are a few duplica- 

 tions of titles. A dash indicates omission of the original reference 

 by an abstracting journal. Superior numbers immediately succeed- 

 ing page references in Chemical Abstracts denote the page section 

 in which the abstract may be found. In the references taken from 

 Biological Abstracts and Physiological Abstracts, the numbers fol- 

 lowing the year indicate the item number for the reference in the 

 respective abstracting journal.
