Rum. 89 



portions will give further insight into the nature of the 

 rum. The colours produced are estimated as before. 



" Colour" used for rum often introduces bitter bodies 

 that spoil the flavour, besides a considerable quantity 

 of free acid. White rum very seldom reaches 0.05 

 per cent, by vol. of (acetic) acid, while 0.25 per cent. 

 is not uncommon in a coloured rum. " Colour" before 

 being added to the white rum is composed as under.

The results given in the table on the following page are 

 the analyses of Demerara coloured rums. The methods 

 used would not form very readable matter, but for those 

 interested I may mention that the ethereal salts have been 

 assayed by estimating the Barium salts of their acids ; 

 while the " fusel oils" were done by Rcese's method as 

 modified by Stutzer and Reitmair. The volume of 

 Chloroform at a temperature of 80 deg. F. for pure, 

 30 per cent, alcohol, was found to be 22.1 c.c.
