The chief chemical differences induced by growth, as indicated 
by the above results, are an increase in the proportion of solid 
matter, including ash, fat and nitrogenous substance. Glucose 
almost entirely disappears from the milk of the ripe nut, cane- 
Sugar replacing it—a fact evidencing synthetic production of disac- 
charide from monosaccharide. : 
Hammerbacher, believing that the endosperm develops directly 
from the milk, determined the quantitative relationships of the 
saline matters contained in each part from the same nut. He gives 
the following as his percentage results : 
. Ash of the Milk. Ash of the Endosperm.* 
Potassium, ia 200 43 882 
Sodium, 0.728 8.392

e The above results indicate a particular increase of the content of sodium chloride 
im the ash of- the developing endosperm and a corresponding decrease of potassium 
Phosphate, See pages 322 and 335. The amount of silicic acid in the endosperm 
18 also noteworthy. See page 335.

* Compare with results of Bachufeu’s analysis, given on page 335. Our own re- 
sults were the same as these qualitatively. Seealso Schaedler Technologie der Fette 
; Seige Oele des Pflanzen- und Thierreichs, 840, 1892, who’ found 3.60 per cent. of iron 
Hos the ash of the endosperm in addition to the above constituents.
