Abstract

Mauzelius (Sveriges Geol. Undersoekning Arsbok 1907); Day and Allen (Bull. U. S. Geol. Survey, 305, p. 35), Hillebrand (Journ. Am. Chem. Soc. xxx 7) and Knight (Chem. News xcvii 122) have shown the effect of fine grinding on the water and ferrous content of minerals and rocks. In this paper we are able to show the effect of continued grinding on some hydrates. The water was determined in each specimen after grinding it a half hour, an hour, an hour and a half, and two hours.
