PART 3 -CARBONIFEROUS. 



Bead at the General Meeting, Ma/rch 4th, 1875. 



TTTE now arrive at the principal and most important part of our 

 * * subject, viz., the coal measures and their adjacent rocks. 

 The various beds of the Carboniferous series may be more extensively 

 displayed in other parts of Great Britain, but in no place are they 

 so well shewn collectively, or so well adapted for study as in our 

 own immediate neighbourhood. Each division is very rich in all 

 the characteristic fossils, in examples of faults, anticlinals, upheavals, 

 denudation, and other types illustrative of Physical geology. 

 Crystallography and Mineralogy are no less fully developed in those 

 crystals and minerals peculiar to the Carboniferous Limestone. 



It is principally to these rocks that we owe our Clifton, Cheddar, 

 Mendip, and other exquisite bits'of scenery, for which Somersetshire 

 and Devonshire are so celebrated. 



We find the Carboniferous follow the Devonian Sandstone 

 gradually and conformably, commencing as argillaceous strata, then
