BIBLIOGRAPHY 



It seemed advisable to classify, to some extent, the list of publications 

 in the Bibliography in order to help the reader, should he require infor- 

 mation upon certain branches of the subject. In several cases where 

 publications deal with anthocyanin from more than one aspect, there 

 has been some difficulty in classification. When this was so, a decision 

 has been made in favour of the point of view, physiological, chemical, 

 etc., to which most prominence has been given in the publication in 

 question. In each class of the Bibliography, the publications are 

 arranged chronologically, and, within the year, in the alphabetical order 

 of the authors' names. In this way the arrangement gives information 

 as to the development of the subject along some of the main lines of 

 investigation. 



The classes selected are: 



1. General work on anthocyanins. 



2. Distribution of anthocyanins. 



3. Natural occurrence of solid and crystalline anthocyanins. 



4. Chemistry of anthocyanins. 



5. Factors and conditions influencing the formation of antho- 



cyanins. 



6. Physiological significance of anthocyanins. 



7. Biological significance of anthocyanins. 



8. Anthocyanins and genetics. 



9. Unclassified references. 



The title, etc., of each paper is accompanied by a short descriptive 

 notice which should not be regarded as a summary of results, but 

 rather as an indication of the nature of the contents. Since many of 

 the shorter and less important publications are not mentioned in the 

 text, they frequently receive in proportion more attention in the Biblio- 

 graphy. On the other hand, the longer and more important publications 

 are usually referred to in detail in the text; in all cases references 

 are given to the text pages.
