The oak wood obtained by Professor Prestwich from the workmen 
may belong to this horizon, though none was met with in the trial-pit. 
The piece of pine-bark and the seed of cornel, found among disturbed 
material in 1888 by Messrs. Reid and Ridley, may both belong to recent 
specimens; these species therefore should not be included in the list without 
further corroboration. A pit sunk at the margin instead of in the centre 
of the channel would probably yield many more dry-soil species, and 
might also yield traces of man. 
Mr. Mitten records the following mosses from this horizon, and it may 
be observed that the conclusions he comes to with regard to the climatic 
and other conditions under which Beds C and D were deposited agree 
closely with those arrived at from an examination of the flowering 
plants :— 
ampullacea? Good. 
Eurynchium striatum, B. and S.; fragments of stem and branches. 
Homalothecium sericeum, B. and S.; » branches. 
Brachythecium populeum ? B. and S. aS BS

‘ These might be derived from a sylvan country in a temperate region 
of low elevation.’ 
Bed E. 
The lignite just described rests on a mass of green carbonaceous clay 
with lacustrine shells, fish-remains, and a few drifted seeds belonging to 
the same plants as occur in the bed above. This clay is not used in the 
brickyard ; but our trial-pit was sunk about a foot into it, and then a 
boring was carried to its base. The upper part of the clay is green, hard,
