tains traces of chlorids. The particular sample taken was at 
some distance from the spring, and had been thoroughly ex- 
posed to the weather. 
‘<The rock of the mound is of just such a character as might 
have been built up by deposition from the water, as it contains 
the least soluble constituents of the water. The process of solidi- 
fication would have been assisted by the silica in the water, 
forming insoluble cementing silicates, as noticed by Professor 
Patrick. The analysis given above shows that there is abun- 
dant silica in the water for this purpose. 
‘Mention has been made of the organic growth in the adja- 
cent springs. The mixed scum, on being heated, changes from 
a dull green to a vivid grass green, and if ignited it swells up 
and emits an ill-smelling vapor, which is evidently nitrogenous 
in its character. A grayish white ash is left, which contains 
much carbonate of lime. This is evidently freshly deposited, 
as 1t is entangled in the alge in granular lumps. 
‘‘A specimen of the white scum noticed above only slightly 
mixed with the green alge, was analyzed. The acid solution 
of the ash contains 1.26 per cent. of soluble silica. This was 
of course combined silica, probably calcium silicate, which be- 
comes the cementing material in the rock. In another sample 
of ash, after removing all the substances soluble in hot water, 
the residue was found to contain 76.46 per cent. of silica.’’
