Vilmorin, leaves gathered October 13, 10 a. m.: 
Glucose_0.398 per cent. 
Maltose_0.186 per cent. 
Sucrose- 0.000 per cent. 
Total_0.436 per cent. 
These results agree in showing the presence of glucose and 
maltose, the latter being present in smaller quantity than the glu¬ 
cose, while cane sugar is present in subordinate quantities or ab¬ 
sent. r ; 
As experiments show that the alcoholic extract of beet leaves 
yields furfurol when distilled with hydrochloric acid, indicating the 
presence of pentoses in this extract, which are susceptible of hydro¬ 
lysis, it cannot be considered as rigorously proven that there is any 
cane sugar present, though the probability of its presence seems 
quite strong. But it is much less than has been found in the 
leaves of other plants which do not store sugar as a supply for the 
future use of the plant.
