Freshwater alluvia, lignite, peat, etc. (some of the { so-called post-glacial alluvia of Britain; { interglacial beds of north Germany, etc.; Alpine { Lands(?); marine deposits of Britain and Baltic { coast-lands). Interglacial { { Britain probably again continental; climate at { first temperate and somewhat insular; submergence { ensues with cold climatic conditions--Scotland { depressed for 100 feet; Baltic provinces { of Germany, etc., invaded by the waters of { the North Sea.
