46 SUMMARY OF CURRENT RESEARCHES RELATING TO 



under the editorship of CM. Schneider. It is a profusely illustrated 

 glossary and encyclopaedia of botany. The work does not pretend to be 

 exhaustive, but to explain those terms which appeal to the general 

 botanical reader and student, omitting those of a purely descriptive 

 nature, such as will be found in most small handbooks, and those which 

 are chemical, physical, and geological, rather than botanical, as well as 

 those relating to micro-technique in the narrower sense. In most cases 

 reference is given to the author of the term and its place of origin. 

 In many cases the article forms a useful resume of what is known on a 

 subject, or of the present position of a theory, and the volume as a 

 whole contains a large amount of information, as well as references to 

 more exhaustive accounts.
