The mineral matters, it appears from the above analyses by Violette, 

 exist in larger quantities in those portions of the root which contain the 

 higher percentages of sugar, but this relation does not appear to hold 

 for entire roots — that is, comparative estimations of sugar and ash in 

 different roots does not seem to establish a lower percentage of ash in 

 roots containing tolerably high percentages of sugar, and that for roots 

 varying in saccharine richness of from 10 to 14 per cent, the proportion 

 of mineral matters present will not vary widely from 0.90 per cent., and 

 this view is supported by the figures given by Champion and Pellet.*
