NATURAL SCIENCE. 



July, 



of the Dewey scheme is the wide appHcation of many of its groups of 

 numbers : for example, each branch of science has the following 

 divisions 



1 Philosophy, Theories, Nomenclature. 



2 Handbooks (" Compends " of Dewey). 



3 Dictionaries. 



4 Essays, Tracts.

These are applied alike to all main divisions from " Religion " to

Again, as we have already mentioned, the geographical numbers 

 of Dewey form a single rational system of universal application, and 

 therefore easily remembered, but here we have the following choice

It seems hardly worth while to criticise these schemes individu- 

 ally ; they may be allowed to answer one another. The alternative 

 classification of zoology, however, calls for a few comments. There
