The beds are subdivided as follows :— 
Cromer Forest-Bed Series. 
Newer Pliocene. ~ Norwich Crag Series. 
Red Crag. 
Older Plocene.  Coralline Crag. 
I do not propose to discuss the Crag Series here, but 
simply to point out that the Cromer Forest-Bed Series occurs 
immediately above the Weybourne beds* of the Norwich 
Crag, and below the Glacial beds. 
However, Prestwich points out? that the base-line between 
the Pliocene period and the Quaternary or Pleistocene period 
is Somewhat arbitrary. He places this base line at the top 
of that very variable deposit the Chillestord Clay and 
consequently includes the Forest-Bed with remains of 
E. meridionalis, in the Pleistocene period, as the lower 
member of the Westleton Series.t 
A list of the Forest-Bed flora and fauna is contained in 
Mr. ©. Reid’s memoir on The Geology of the Country 
round Cromer, pp. 62-80, and in Mr. EK. 'T. Newton’s memoir 
on The Vertebrata of the Forest-Bed. (Geol. Survey 
Memoirs, 1882.) The absence of 4. primigenius (mammoth) 
should be noted. 
If, then, we follow Prestwich, we shall class eolithic man 
as belonging to the early Pleistocene; if, on the other hand, 
we follow Lyell, we shall regard him as of late Pliocene time. 
The geological facts of the case, however, are the really 
important points; the nomenclature, however useful as a 
framework for the scientific appreciation of those facts, 1s in 
this instance a secondary consideration. 
As Dr. Hicks pointed out in his last Presidential Address 
at the Annual Meeting of the Geological Society in 1898, 
“all the evidence tends to show that the so-called Tertiary 
and Quaternary periods merged gradually one into the other, 
and were not separated by any great break in Britain. The 
higher mountains, before the close of the Tertiary period, 
must have been covered in part by ice and snow, and the 
so-called “Glacial period” can only have a chronological 
importance as indicating the increased intensity and climax
