Mr. Boyd Dawkins is of opinion that Cervus Elaphus, C. megaceros, and 

 C. capreolus ave not to be regarded as the Pliocene age, while poligniacus is a 

 well-known Pliocene species; and this peculiar mixture of cervine species indi- 

 cates that the forest bed belongs rather to an early stage of the Pleistocene 

 than to the Pliocene ; and this inference is corroborated by the presence of 

 the Mammoth which is so characteristic of the Pleistocene age.f 



From the occurrence of such varied and large mammalia, most of them 

 of extinct species, Prof. RAilSAY tliinks they could not have originated in a 

 small detached island like England, but fornaed parts of large families that 

 inhabited the north of Europe, America, and Asia, at various minor periods 

 of geological time, and they could only have passed into our area by the 

 union of England with the continent. § 



In the last edition of the "Principles of Geology," (vol. 1, 

 ch.x,) attention is drawn to the singular analogy existing between 

 the forest bed of Diirnten, near Zurich, and that of Cromer, 

 just described. — 



Both contain the cones of the Spruce and Scotch fir, and the seeds and
