In the chlorhydric acid solution of the paragraph next but one 
preceding, there was found (in terms of per cent of the ashes taken), —

Since a very considerable amount of alkaline chlorides was obtained 
from the ashes by Lawrence Smith’s process, it appears from the 
foregoing that a good part of the alkaline matters in the ashes 
must be held with sufficient firmness to resist the action of hot 
acid of the strength indicated. 
To determine the amount of matter soluble in pure water, 9250 
grammes of the sifted ashes were placed in a clean water-soaked fir- 
kin provided with a plug at the bottom and percolated methodically 
with pure distilled water, free from ammonia, An amount of perco- 
late was collected equal to the volume of water that was required to 
moisten the ashes to the point that a drop fell from the, orifice at the 
bottom of the firkin. The 10 litres of liquid thus obtained were 
evaporated to the volume of 4 litres, and definite fractions of the 
latter were taken for the determinations the results of which are now 
in question. The total amount of matter dissolved by the water was — 
equal to only 0.114 per cent of the ashes. By analysis it appeared 
that the water had dissolved from the ashes :—

besides sulphuric acid in combination with the lime, and as much 
soda and lithia as were contained in an amount of their mixed chlo- 
rides equal to 0.0193 per cent of the ashes taken. During the evapo- 
ration of this aqueous solution it was noticed that crystals of gypsum 
Separated freely after a certain degree of concentration had been 
reached. The residue obtained by evaporating the solution to dry- 
ness had a faint but distinct green color. Neither alcohol, ether, nor 
water had any action upon the coloring matter in the cold, but when
