1200 Acids. 



1300 Aldehydes and Ketones. 

 1400 Carbohydrates ; Glucosides ; Resins. 

 1500 Amino- and Azo-coinpounds. 

 1600 Mixed Cycloids. 



1700 Organo-metallic and allied compounds. 



1800 Alkaloids. 



1900 Proteids. 



2000 Coloured compounds. 



2500 Operations in Organic Chemistry. 



3000 Analytical Chemistry. 



3500 Theoretical and Physical Chemistry. 



4000 Physiological Chemistry. 



The above are only the main sections proposed by the Committee ; 

 the subdivision between Nos. 1500 and 1600 (Amino- and Azo-com- 

 pounds) will serve to exemplify the next stage of subdivision in the 

 schedule — 



1510 Amino-paraffins. 



1520 Amino-derivatives of unsaturated open chain hydrocarbons. 



1530 Amino-derivatives of benzenoid hydrocarbons. 



1535 Amino-derivatives of reduced benzenoid hydrocarbons. 



1540 Acid amides and allied compounds. 



1545 Imides, imido-ethers, &c. 



1550 Azo-compounds (open chain). 



1560 Azo-compounds (closed chain). 



1570 Diazo-compounds (open chain). 



1580 Diazo-compounds (closed chain). 



1590 Unclassified amino- and azo-compounds. 



Each of the divisions 1570-1540 are subdivided again into mona-, 

 mino-, diamino-, &c, derivatives, which are arranged as in other 

 series.
