century de Maillet conceived a project for estimating the diminution 
of the water. He also quotes Pettersen (Guou. Mac. July, 1879, 
p- 298), who has shown, as regards Scandinavia, that the changes of 
that coast-line must have gone on quite uniformly in the tracts from 
the Varanger Fjord to Bergen, a distance of nearly 2000 miles, nor 
does there appear evidence of any portion of the peninsula sinking. 
The subject is dealt with as an essay in favour of a certain thesis, 
and the points which tell against it are not brought into prominence ; 
nevertheless, the pamphlet is a highly suggestive one, and contains 
much that is worthy of consideration on the part of geologists, by 
whom the “ mouvement de bascule,” so ably disputed as regards the 
Scandinavian peninsula, has perhaps been too frequently urged.

March 24, 1880.—Robert Etheridge, Hsq., F.R.S., President, in 
the Chair.—The following communication was read :— 
“The Newer Pliocene Period in England.—Part I. Comprising 
the Red and Fluvio-marine and Crag and Glacial Formations.” By 
Searles V. Wood, Hsq., Jun., F.G.S. 
The author divided this part of his subject into five stages, com- 
mencing with 
Stage I. The Red Crag and its partially fluvio-marine equivalent. 
The Red Crag he regards as having been a formation of banks and 
foreshores mostly accumulated between tide-marks, as shown by the 
character of its bedding. The southern or Walton extremity of 
this formation, which contains a molluscan fauna more nearly allied 
to that of the Coralline Crag than does the rest of it, became (as did 
also the rest of the Red Crag south of Chillesford and Butley) con- 
verted into land during the progress of the formation; while, at its 
northern or Butley extremity, the sea encroached, and an estuary 
extending into Hast Norfolk was also formed; during which geo- 
graphical changes a change took place in the molluscan fauna, so 
that the latest part of the Red Crag proper and the earliest part of the 
fluvio-marine (both containing the northern species of mollusca and 
those peculiar forms only which occur in older glacial beds) alike 
pass up without break into the Chillesford sand and laminated clay, 
which form the uppermost member of the formation. He also 
regards the principal river of this estuary as flowing into it from 
North Britain, through the shallow preglacial valley of Chalk, in 
which stands the town of Cromer, and in which the earlier beds of 
Stage II. accumulated in greatest thickness. The forest and fresh- 
water beds, which in this valley underlie the beds of Stage II., he 
regards as terrestrial equivalents of the Red Crag; and having ob- 
served rolled chalk interstratified with the base of the Chillesford 
clay in EHaston-Bavent cliff, he considers this to show that so 
early as the commencement of this clay some tributary of the Crag 
river was entered by a glacier in the Chalk country, from: which
