I may remark here, that I use the term Calcareous Slate in pre¬ 
ference to Carboniferous Slate,-—a name recently given to this sub¬ 
division of the formation, because all the slates in the whole forma¬ 
tion are carboniferous slates: and those slates above the main body of 
the limestone, in the coal-measures, are more eminently carboni¬ 
ferous than the slates which lie below it, that is, those in question, 
which are eminently calcareous in their nature, and generally inter- 
stratified with thin beds of limestone.
