MEMOIR OF ROBERT WIGHAM. 
In this well also the Weybourn Crag rests immediately on 
the Chalk. The micaceous clay, which seems to represent the 
Chillesford Clay, here lies between two beds of shelly Crag. The 
upper one, however, may belong to the Forest-bed, which, west of 
Cromer, often shows marine intercalations. At present, we are 
unable to distinguish between the marine fauna of the Weybourn 
Crag and that of the Forest-bed ; for the land and fresh-water 
species of the Weybourn Crag all (with the exception of Litho- 
glyphus) range upward into the Forest-bed, while the marine fossils 
of the Forest-bed (except some extremely rare mammals) are all 
found in the Weybourn Crag. Further knowledge may obliterate 
entirely the distinction between Crag and Forest-bed. A close 
study of the fauna does not support the view that the Forest-bed 
can be separated from the Crag and made into the base of a new 
division, to be classed as Pleistocene.

MEMOIR OF ROBERT WIGHAM.

Read 29th October , 1901. 
In the ‘Transactions’ of our Society there have been published 
from time to time memoirs of Norfolk Naturalists of bygone 
days ; but up to the present there has not appeared any notice 
of Robert Wigham, who was an enthusiastic student of Natural 
Science, and whose work in the County as a field naturalist 
entitles him to such a record.
