or.) BOTANY. 



The Primary Divisions adopted correspond to the recog-nised 

 branches of the science of Botan3\ It has not been thought 

 desirable to adopt a taxouomic arrangement throughout, as \n 

 Zoology, because a large part of the work done in Botany i.s^ 

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

 be readily classed under taxonomic headings. In particular, the 

 whole subject of Vegetable Physiology is included under Botany, 

 whilst Animal Physiology forms a distinct science by itself. On 

 tl)is account, in many cases cross references, by means of 

 duplicate slips, will be nece.ssary. 



It is considered essential that all works on fossil plants should 

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

 science of Palaeontology (K). References to Palfeobotanical 

 works are intended to be distributed under their appropriate 

 headings in the scheme, whether taxonomic or otherwi.50, such 

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

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

 both to recent and fossil forms it should be marked*|. Thus a 

 paper on the " Anatomy of the Stem of Lepidodendron''' would 

 be catalogued under 2040 (Anatomy of Stem), and under 6700 

 (Vascular Crj'ptogams), as well as in the Pal-aeontological 

 scheme. The stmtir/raphical grouping of entries relating to 

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