. Subject Index 



This index contains: 1. The various subjects discussed in Beijerinck's papers. 

 2. The latin names of organisms, which are of special interest. The subject discussed 

 with regard to these organisms is given in a subtitle. 3. Ordinary names of organisms 

 in the language in which they appear in the various papers. In so far as this language 

 is other than English, cross references are given to the Enghsh names. However, no 

 cross references are given to the Latin names included èither in this index or in index II. 

 The indication of various concepts did undergo alterations during the years 1877- 

 1927, (e.g. the concept "mutation", which before 1912 Beijerinck mdicates by "va- 

 riation"). It has been attempted to eliminate as much as possible the difficulties 

 arising herefrom by cross references or by putting more concepts in a subtitle. 



Roman figures refer to the number of the volume. Pages marked with an 

 asterisk refer to illustrations. Numbers printed in heavy type refer to pages of 

 special interest.
