In particular places bands of plate intervene between the limestone 
and the gritstone, but the most prevalent type is that given above. 
The same character of the terms of the Yoredale series will be found 
in Mr. Westgarth Foster’s Section of Aldstone Moor. Coal occurs 
with every one of the terms, but locally and somewhat irregularly, except 
between the main and underset lime and above and below the middle 
limestone. The number of these terms is found to be the same in all 
parts of the Yoredale series, except where it undergoes rapid changes 
toward Great Whernside and Fountains fell. 
Variation of the terms of the Yoredale series . — Proceeding from 
Hawes to the south, the terms of the series change greatly : and most 
of the gritstones are completely lost, and the limestones diminished in 
thickness and debased in quality by admixture of argillaceous matter. 
In Ingleborough, the fourth term has no limestone, but the gritstone, 
one of the most continuous of the Yoredale rocks, is fully developed. 
Proceeding westward, the gritstones become more constantly laminated, 
as may be seen by comparing the sections of Hawes and Wharnside, 
p. p. 37, 38 — northward little changes appears ; eastward and south-east 
ward both grits and plates diminish in thickness, while the limestones 
grow thicker, except those of the fourth and fifth group which die away.
