1869.] SEARLES WOOD — BOULDER-CLAY. 111
Mr. Searles V. Wood, 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.
