From W. E. Darwin [3 March 1872]1
Sunday
My dear Father,
I send you the dirt residue from Chalk as Prof. Forbes would probably be able to judge whether this is the result of soakage.2
Parsons weighed them when quite dry, & he is a good chemist; He says B. gets wet from having traces of Chloride of Calcium.3
