[38] The blue green acid is not homogeneal in its composition, it is
composed of the blue green spherules and the bright green acid. The
blue green spherules are of greater specific gravity than the dark
green acid, probably because they contain little or no water.
[39] The composition of the acids thus marked, is given from
calculations.
