 the country itself, afler which Ihey liave successively spread

 countries may also have laken place across the sea lo all 

 parts of the country; most easily, however, to the northern- 

 mosl parts, and to south and south-east Greenland. There 

 is no reason lo assume any post-glacial immigration over a 

 connected belt of land from Europe. The slight surplus of 

 FLnropean types as compared with American in Greenland 

 is due to the greater abundance of European types in South 

 Greenland; and their presence here is suflicienlly explained 

 by the similarily of climalic conditions to those of western 

 Europe, and by a grealer facilily for planl migration, from 

 Iceland especially, to South (ireenhuul Ihan from America
