i) The charcoals which can be used in the analysis of sugars have 

 very different densities. They differ also considerably in composition, 

 since some have 81 per cent of ash, whilst others' have only traces. They 

 have very different decolorizing power. 



2) From a pure solution of sugar, they all absorb more or less sugar. 

 This absorption is less when the sugar solution contains lead. 



3) From a solution of molasses clarified by subacetate of lead, the 

 charcoals absorb no sugar, or only traces ; some even increase polarisation 

 to the right. 



4) When a solution of molasses is analysed by Clerget's inversion 

 process, it is found that certain charcoals cause a diminution in the sugar, 

 whilst others have no appreciable effect. The special charcoal for deco- 

 lorizing wines gives the best results. 



5) This particular charcoal does not absorb the reducing substances 

 contained in beet molasses nor in the non-fermented residue left after 

 distilling sugar-cane molasses, but does appear to absorb non-fermented 

 polarising substances in this residue. This sugar-cane molasses residue 

 contains 7 to 9 per cent of reducing sub.stances, whereas beet molasses has 

 only 0.7 to 2.5 per cent according to the conditions of fermentation, though 

 in special cases it may have more tham 2.5 per cent.
