I have dwelt longer upon the history of the Rheetic bone 
bed, because of its greater extent and possible application 
for economical purposes, for it is the only one which would 
be likely to be available in this way. The discoveries of 
modern science have laid open so many new sources for the 
practical application of the rocks, which form the crust of 
the earth that we can scarcely set a limit to their utilization, 
and we may look forward to many other and as yet hidden 
stores of general advantage to the public. * 
* One instance of this among many may be cited. The Kimmeridge Clay on the
