Weight Of Stone

A long list of stones, giving the weight per cubic foot of each, was prepared by Mr. C. H. Smith for the Mineral Statistics published at the Museum of Practical Geology.

The information contained in that list has been given in the Tables, pp. 18, 39, 67, et seq., and it will therefore not be repeated.

The following Table shows approximately the weights of different classes of stone, and may be useful.
