Development of Diatomaceous Earth in Nova Scotia

CIM Bulletin1928
DIATOMACEOUS or infusorial earth, also called diatomite; fossil meal, or kieselgubr, is derived from the lowest form of vegetable life, the unicellular alga:. It consists of the siliceous remains of extremely minute aquatic plants, which exist in both salt and fresh water. Light is a prerequisite to their development. These very small particles secrete silica in much the same way that molluscs secrete lime to form their shells.
