1869. ] SEARLES WOOD—BOULDER-CLAY. 111 
Mr. Seartes V. Woop, Jun., stated that he had relied on Mr. 
Gwyn Jeffreys’s works for his classification of the shells as being 
arctic or otherwise. He regarded the succession of the various 
members of the Glacial series of the eastern side of England as well 
founded, and borne out also by the molluscan remains. He utterly 
repudiated the notion that the Chillesford, Bridlington, and Kelsea- 
Hill beds were on the same horizon. He believed nearly the whole 
of the Scotch beds to be newer than those of the Middle and Lower 
Glacial. He quoted Prof. Phillips as suggesting a change in the 
relative elevations around Shap Fell since the dispersion of the 
boulders, and offered as his own explanation the hypothesis that 
the passes by which the boulders travelled were those which, though 
at the higher levels, were the soonest freed from ice. He thought 
that the direction of the current was influenced by other causes than 
the general trend of the rocky dividing ridge.
