Role of tannin in plants, particularly in the fruit, C. Gerber ( Compt. Rend. Acad. 

 Sci. Paris, 124 ( 1897), No. 20, pp. 1106-1109).— The author thinks the principal function 

 of tannin is to check the formation of poetic compounds in the fruit and also to 

 prevent the fermentation of the sugars. In such fruits as that of Diospyros kaki the 

 tannin disappears hy complete oxidation without forming any carbohydrates.
