Th os. Belt — The Glacial Period in Norfolk. 
Limestone and tke New Red Sandstone, and a passage from one into 
the otker, tliere are at least three subdivisions wanting that sliould 
come between tbese formations. 
I am quite willing to admit tbat tliere is a muck greater degree of 
conformity between tke Permian and tke New Red Sandstone tkan 
between the Carboniferous and the Permian, and that the great 
division between tke Primary and tke Secondary formations should 
be at tke bottom and not at tke top of tke Permian. Tke links that 
bound tke Permian to tke Carboniferous are now nearly all broken. 
Tke Lower Red Sandstone of Sedgwick, or Rotkliegende of 
Murchison, lying below tke Magnesian Limestone, witk its coal- 
plants and even coal-beds, is now proved to be eitker Coal-measures 
or Millstone-grit, and tke Permians of Staffordskire and War w ick - 
skire are now said to be Upper Coal-measures of a red colour. 
Tke relation between tke Permian and tke New Red Sandstone is 
an interesting question, but tke trutk can only be arrived at by a 
statement of facts. I kave nowhere myself seen a passage upwards 
from tke Permian into tke New Red Sandstone, but I will not say 
such a tking does not occur. 
III. On THE FlEST StAGES OF THE GlACIAL PeKIOD IM NORFOLK 
HE publication in the last Quarterly Journal of tke Geological 
Society of tke most instructive p>aper by Messrs. S. V. Wood, 
jun., and F. W. Harmer, on tke Later Tertiary Geology of East 
Anglia, and one by tke latter autkor on tke Kessingland CHff-section, 
induces me to offer tke following remarks, witk tke kope that my 
views may be considered by geologists wko kave rnade tkis question 
tkeir study. 
Messrs. Wood and Harmer skow very clearly that over most of 
Norfolk and Suffolk, laminated brick-eartks were originally spread 
out, and afterwards more or less denuded, and in some parts greatly 
contorted and disturbed. At tkeir base lie pebbly sands, wkick are 
partly tlie “ Westleton beds ” of Mr. Prestwich, and above them lie 
tke “ Middle Glacial sands and gravels ” of Mr. S. V. Wood, jun. 
In nearly all tke sections given by tke autkors in tke above-named 
memoirs, and in most of those that I kave myself examined, tbe 
brick-eartks and pebbly sands rest directly on tke Ckalk or on tke 
Newer Tertiary beds. In tke few exceptions, as in tke Cromer Cliff- 
section, and near Tketford, wkere tkese brick-eartks are underlain 
wkolly or in part by tili, tkere is muck disturbance of tke strata, and 
tke beds are greatly contorted and folded, as kas been very fully 
described by Sir Charles Lyell. 
I kave in various papers urged that tke ice that flowed down tke 
bed of tke German Ocean reacked to and invaded tke coast of 
Norfolk ; and it may very well kave been reinforced by ice tliat 
kad rounded tke Southern end of tke Pennine Chain from tke 
and Suffolk.
