The chief chemical differences induced by growth, a.s 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 : 



99-993 99-318 



The above results indicate a particular increase of the content of sodium chloride 

 in 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 

 is also noteworthy. See page 335.

* Compare with results of Bachofeu's analysis, given on page 335. Our own re- 

 sults were the same as these qualitatively. See also Schaedler Technologic der Kette 

 und Oele des Pflanzen- und Thierreichs, 840, 1S92, who found 3.60 per cent, of iron 

 in the ash of the endosperm in addition to the above constituents.
