It would seem ae the preceding didetintion that all the 
rocks essential to Werner’s Independent Coal Formation

vol. 2, p. 508,) and also the greenstone and amygdaloid

the coal formation above described, but, for aught I can see, 
even the old red sandstone; and, iadeed: what fragmented 
rock will it not include ?*. And besides, many of the argilla-
