01) BOTANY. 



The I'rimaiy Divisions adopted correspond to the recognised 

 branches of the science of Botiiuy, It has not been thonyht 

 desirable to adopt a taxonomic arrang-ement throug-hout, as ia 

 Zoolog-y. because a hirge part of the worlv done in Botany is 

 written from other than taxonomic points of view, and could not 

 be readily classed under taxonomic heading-s. In particular, the 

 whole subject of Vegetable Physiology is include<l under Botany, 

 whilst Animal Physiolog-y forms a distinct science by itself. Uu 

 this account, in many cases cro.-s references, by means of 

 duplicate slips, will be necessary. 



It is considered essential that all works on fossil plants should 

 appear in the Botany scheme, as well as under the separate 

 science of Pala.^ontology (K). Peferences to Palfeobotanical 

 works are intended to be distributed under their appropriate 

 headings in the scheme, Avhether taxonomic or otherwise, such 

 works being- indicated by a special mark (such as a f), identical 

 with that used to indicate fossils in Zoology. If a slip relate 

 both to recent and fossil forms it should l)e marked*t. Thus a 

 paper on the '• Anatomy of the Stem of J.e])idodendro7i" would 

 be catalogued under 20i0 (Anatomy of Stem), and under (>70(' 

 (Vascular Cryptogams), as well as in the Palaeontological 

 scheme. The stratigrajiliival grouping- of entries relating to 

 Fossils will, of course, be left exclusively to Palaeontology.
