hood of protruded masses of granite. The strata consist generally 
of a hard, fine or coarse greywacke, passing occasionally into roof- 
ing-slates, and destitute of fossils, except in the finer schists in which 
the Graptolites foliaceus has been found. The strata which break 
out from under the carboniferous basin of Girvan Water in Ayrshire, 
are next described, and shewn to contain many silurian fossils. 
Lastly, a synoptical table is given of the great groups, ranging from 
the carboniferous series to the lowest beds of the north of England, 
the classification being as follows :—Ist, the Carboniferous series ; 
2d. the old red sandstone (Devonian system) ; 3d, Silurian system ; 
4th, the Subsilurian, or upper Cambrian ; 5th, the lower Cambrian, 
including the great groups of North Wales, between the Bala lime- 
stone and the old roofing slates of Cumberland ; 6th, the lower Cum- 
brian or Skiddaw slates, and containing provisionally the chloritic 
slates of Anglesea and Caernarvonshire.
