Florida Phosphates. The Origin of the Boulder Phosphates 
of the Withlacoochee River District.* Eng. Min. Jour. 
LIII, p. 380, 1892. 
In this paper the theory is advanced that the phosphate 
boulder is a true fossil, the boulder being the phosphatic 
skeleton of a gigantic foraminifera, while the soft phos¬ 
phate is supposed to be the germ spores or bud of the ani¬ 
mals, or the comminuted debris of the animals themselves.
