WEYMOUTH. 
(Gepp, ‘ Fossil Plant-remains in Peat,’ /ourn. Botany, 
Vol. XXXIIL, pp. 180-182. 
1895.) 
Cakes of compressed peat thrown up near Weymouth 
have yielded a few plants, among which is the white water- 
lily. The peat is apparently derived from the seaward edge 
of Lodmoor, which lies to the north-east of Weymouth. 
Its age is not earlier than Neolithic, and at present it is 
impossible to say whether it may not be entirely Post- 
Roman.
