Стр. 114 - ... height; but the eocene appears a short distance north of it, separated from the secondary by a strip of alluvial soil. Here, however, the two upper strata only are visible, the superior bed of limestone being but a few feet in thickness, whilst at Claiborne the corresponding one is about forty-five feet thick.

Стр. 269 - ... to the western slope of the roof some counteracting tendency, or relieve it from some portion of the upward pressure.
