The saline constituents of course differ somewhat in every 

 case, particularly as far as the lime compounds are concerned. 

 The following analytical results, (Trommer & Rode), may give 

 some idea about their general character. 



One hundred pounds of ash constituents of beet-sugar molas- 

 ses contain of: — 



The residual liquid left after the fermentation of the molas- 

 ses is usually evaporated and the solid mass subsequently 

 calcined. The beet-sugar manufacture furnishes in this form 

 quite a large quantity of valuable saline compounds for general 

 industrial purposes. One hundred pounds of tlicse calcined 

 saline substances contain from 45 to 48 per cent of soluble 

 constituents of a composition more or less corresponding with 

 the following figures : —
