10. Currant leaves and flowers. 
Two hundred grains of the leaves gave 4*00 grs. of ash, and the same weight of the 
flowers gave 2*95 of ash; but the analysis was not finished. The leaves are particularly 
rich in soda and the phosphates. The analysis of the flowers was undertaken for the pur¬ 
pose of determining the amount of silica, an element which I have found rather abundant 
in floral organs, particularly the petals. In the ash of the blossom of the currant I found 
9 per centum of silica, and 28 per centum of potash, a result which indicates the predomi¬ 
nance of potash rather than soda in these organs. 
N. B. It is due me to state, that in the following analyses having my initial, in the two preceding sheets, the 
carbonic acid was not obtained, viz : Analyses of the Hemlock and Sugar Maple, page 319; those of the Red Elm, 
p. 323 ; those of the Hickory, p. 325; those of the Black Birch, p. 326 ; and those of the Red Birch; p. 328. These 
are the only cases, in my analysis, where the carbonic acid is inserted without being actually determined : it was 
retained in these instances through mistake. In the following analyses having my initial, in the present sheet, the 
carbonic acid was not determined, and is not inserted, viz : Analyses of the Plum, p. 330; those of the Peach, top 
of p. 331 ; and of the root of the Apple tree, p. 332. J. H. Salisbury.
