56 Origin of the British Flora. 



Bacton, Norfolk. 



(Reid, ' Pliocene Deposits of Britain,' Memoirs Geol. 

 Survey, 1890; Reid, 'Geology of the Country around 

 Cromer,' Memoirs Geol. Survey, 1882.) 



The Cromer Forest-bed at Bacton yields cones of 

 Pinus sylvestris and Picea excelsa, and rhizomes of 

 Osmunda; the principal fossiliferous localities are, how- 

 ever, close to Ostend Gap, a short distance to the south- 

 east, and are described under that heading. 



Ballaugh, Isle of Man.
