It will be also observed that the trap must rest in some cases on 

 much denuded surfaces of the lower rocks, great thicknesses occurring 

 where there were originally hollows.

Comparing these two sections from the topmost trap downwards, 

 that is, in the reverse order to that in which they are above written, 

 we find that the 175 feet (No. 4) of the first section becomes expanded 

 to a total of 200 feet, and that the intercalated shales have thickened, 

 and are distinctly seen. Below this, the fine felspathic sandstone main- 

 tains a constant thickness of about 50 feet in both sections, bat below it 

 the bed of trap is the difference between 165 and 225, or 60 feet 

 thicker in the second than it is in the first section. These two sections
