Reducing sugars. — The reducing sugars determined as dextrose 

 in pure honey according to Leffmann and Beam vary from 60 to 

 75 per cent. In the more distinct types of honeydew honey the 

 reducing sugar content is somewhat below 60 per cent. 



Acidity. — The acidity of the honeydew honey is high, amounting 

 to 0.172 per cent as formic acid, this being about three times the 

 amount found in the algeroba honey. 



Nitrogen. — The nitrogen content of both the algeroba and the 

 honeydew honey is low, sample Xo. 1 containing 0.05 per cent and 

 sample Xo. 14, 0.04 per cent. 



The honeydew honey obtained from the Hawaiian sugar-cane fields 

 may be compared to that of the pine forests as examined by Dr. 

 H. W. Wiley. According to Wiley, 0 the hone}^dew honey of America 

 is characterized by right-handed polarization at ordinary tempera- 

 tures, deficiency of invert sugar, and high ash content. Hawaiian 

 honeydew honeys agree in the high ash content and right-handed 

 polarization.
