7. The mother liquor, or bittern pan Lymington, presented, on 
analysis, an unaccountable variation from the similar fluid sent 
from Scotland, and gave a much larger proportion of sulphate 
of magnesia. A considerable quantity of this salt had, more- 
over, crystallized in the bottle which contained the liquid. Its 
specific gravity was 1280. One thousand parts of the dry 
salt contained of
