 six times as much silica, and two and a half times as much nitrogen. 

 The potash was some 20 per cent higher in the stalks than in the 

 leaves. 



The relative ash compositions and relative amounts of asn con- 

 stituents in the dry substance of the plants from the different plats 

 are given m Table XIII, the percentages of the diiTerent elements 

 in the plants from Plat I being taken as 100 in each case. In Table
