180 Reid. — Notes on the Geological History 
Mr. George Barrow. This was obtained thirteen feet down in 
the peat at Corb, in the Highlands, at a height of over 1400 
feet above the sea. It yielded a few upland plants, but only 
species still found in similar situations. 
At the base of similar hill-peats in the Yorkshire moors, 
large well-grown oaks are found, but the associated seeds have 
not been collected, and it is doubtful whether the oaks alone 
are sufficient evidence of a change of climate. 
From the raised marine deposits with arctic shells bordering 
the Firth of Clyde, I have determined fifteen species, prin- 
cipally sent me by Mr. Thomas Scott and Mr. Bennie. 
Though associated with a decidedly northern marine fauna, 
there is nothing arctic about the plants. At that time the 
temperature of the air was apparently higher than that of the 
sea in the Clyde district. The plants, though few, are interest- 
ing, for they include dry-land forms — such as Bartsia Odontites 
and Thymus Serpyllum — not known from any other localities. 
The ‘ submerged forests 5 and associated deposits in Holder- 
ness yield a few species, all still living in the district. But 
from another bed in the same part of Yorkshire, Betula nana 
has been obtained, at Bridlington by Dr. A. G. Nathorst, and 
at Holmpton by myself. 
In Norfolk a few plants occur in a postglacial river-deposit 
at Mundesley, associated with the elephant and river-tortoise ; 
and Mr. H. N. Ridley and I have lately obtained a number of 
others from Hoxne, but have not yet finished the de- 
termination. 
From peat below the sea-level at the Albert and Tilbury 
Docks, I have received a few specimens from Mr. Spurrell. 
All the species are still living in the neighbourhood. 
A sample of similar peat from Southampton Docks, given 
me by Mr. Whitaker, yielded a few widely distributed 
species. 
The different localities from which interglacial plants have 
been obtained are nearly all in Scotland. This is largely due 
to the thorough way in which the Scotch glacial deposits 
have been searched, for similar beds certainly occur in England,
