The ash content is highest in closed flowers, next highest in open 
flowers, and lowest in the stems. A higher percentage of the ash of 
stems is insoluble in hydrochloric acid than in the case of the flowers, 
although calculated back to the original material the difference is 
slight. It is only when the ash and the ash insoluble in acid are 
markedly above the normal for flowers that much importance is 
attached to these determinations. 
A striking thing in the figures for nitrogen and for phosphoric acid 
is that they run fairly constant for the same material (Chrysanthemum 
dnerarisefolium) , no matter what its source. This uniformity in the
