Abridged Schedule of Classification for Chemistry * 



Chemical Bibliography. 



0000 Philosophy. 

 0010 History. 

 0020 Biography. 



0030 Dictionai'ies, collected works, text-books. 

 0040 Pedagogy. 



0050 Addresses, lectui'es, essays and theses. 



0100 Chemistry (Specific) of the Elements, to include all entries 

 relating to the elements generally, or which cannot be 

 referred to any one of the known elements. 

 0110 Alamiuium. 

 0120 Antimony. 



0130 Argon, followed by the other known elements at similar 

 numerical intervals and arranged in alphabetical order up 

 to— 

 0840 Zirconium. 



Entries made under any element may be furlher sub-divided ac- 

 cording to the nature of the compounds in which they occur, and are 

 arranged into five further sections in such order that the entries relat- 

 ing, a, to the history or origin of the substance shall come first, fol- 

 lowed by, /3, its preparation or manufacture ; y, its structure, or theore- 

 tical nature ; 8, its interactions or use ; and € its compounds. 

 0900 Laboratory Procedure. 

 1000 Organic (Carbon) Chemistry (Specific). 

 1010 Hydrocarbons generally with the following recognised 



groups — 

 1020 Paraffins. 



1030 Unsaturated open chain hydrocarbons. 

 1040 Benzenoid hydrocarbons. 



1050 Reduced benzenoid hydrocarbons (terpenes, &c.). 

 1060 Unclassified hydrocarbons. 



When necessaiy these groups of hydrocarbons are further sub- 

 divided into isologous groups, in each of which the compounds are 

 entered in homologous order. 



1100 Alcohols and Ethers with sub-divisions as in the case of 



hydrocarbons ranging from 1110 to 1150. 

 1200 Acids. 



* From the Report of the Royal Society Committee, March 30th, 1898. The 

 nnmbers employed to distinguish the snb-divisions are sufficiently separated to 

 admit the interpolation of new sub-diviaions aa the subject expands.
