riatic acid is saturated with ether. The natural chlorophyll which may 
be extracted from leaves by means of alcohol, may be easily decomposed 
into its constituents by shaking it with this mixture of muriatic acid and 
ether. The liquid first takes a i 
riatic acid takes a beautiful blue, while the ether separates, holding the 
yellow coloring matter in solution. Frémy calls the blue substance 
phyllocyanin, and the yellow phylloxanthin. When alcohol is added, so 
that the two liquids mix, a green is again produced, of the color of the 
washing is very easy and rapid; the dried salt may be ignited in a pla 
tinum crucible, and does not fuse at a red heat. 
Pyrophosphoric acid is also precipitated completely by the acid nitrate 
which is much more voluminous 
The metaphosphates behave in the same manner, but the precipitate 
requires a longer boiling to be completely transformed into the ordinary 
phosphate.
