 which lie in the direct course from Madeira to the Canaries, though 

 somewhat nearer to the latter than to the former, give them an espe- 

 cial interest in the eyes of geographical naturalists, — particularly 

 those, however, who have had 'an opportunity of studying the pro- 

 ductions of the two neighbouring groups. The qucestio vexata, as to 

 whether these several Atlantic islands are not, in reality, the mere 

 exponents or outposts of an immense continent now for the most 

 part submerged, may perhaps never be solved ; yet certainly one of 

 the best methods of helping towards a solution is carefully to 

 examine the fauna and flora of what seem to be its detached por- 

 tions, and then closely to compare them with each other, in order to 

 ascertain whether they possess sufficient in common (after every 

 reasonable allowance has been made for the accidental intermission
