III. — On Sugar-Beets and Beetroot Distillation. By 
Dr. Augustus Voelckek, F.R.S. 
The existence of crystallizable sugar in beetroots was discovered 
in 1747 by tlie Berlin chemist Marggraf, who obtained from this 
root from 4^ to 6 per cent, of sugar identical in all essential 
points with that derived from sugar-cane. 
For fully half a century Marggraf 's discovery attracted but 
little attention in non-scientific circles ; and bore little or no 
practical fruits until the beginning of the present century. 
Experimentally, no doubt, sugar was extracted from beetroot 
long before Napoleon I. encouraged so greatly the establishment 
of beetroot-sugar factories on the Continent ; but, on a com- 
mercial scale, beetroot-sugar was, probably, not produced before 
1809.
