BLACK BURN, EAST TARBET. 
From the Clyde Beds at this place Mr. David Robertson 
obtained seeds of Rubus Ideus. The sub-Arctic character 
of the associated marine mollusca causes these deposits to 
be here classed as Late Glacial. 
BLASHENWELL, DORSET. 
(Reid, ‘An Early Neolithic Kitchen-midden and Tufa- 
ceous Deposit at Blashenwell, near Corfe Castle,’ Proc. 
Dorset Field Club, Vol. XVII, pp. 67-75. 1897.) 
The calcareous tufa contains only recent species of 
mammals and mollusca, with charcoal and unpolished flint 
implements of early Neolithic type. The plant-remains 
are impressions of leaves and twigs, with decayed wood and 
hazel-nuts. The only determinable plants found were :— 
Ulmus montana (?). Quercus Robur. 
Corylus Avellana. 
BOVEY TRACEY, DEVON. 
(Pengelly and Heer, ‘On the Lignite Formation of 
Bovey Tracey, Phil. Trans., Part II. 1862; Nathorst, ‘On 
the Distribution of Arctic Plants during the Post-glacial 
Epoch, Journ. Bot., n.s., Vol. IL, p. 225. 1873.)
