One of the subjedls brought prominently into notice by the 

 observations taken on the Challenger Expedition is the relation of 

 the surface fauna of the ocean to that of the bottom deposits. 

 So far as the Foramhiifera are concerned the question is by no 

 means a new one; but the Challenger colle(5tions, and those more 

 recently made by Mr. Murray on the cruises of the "Knight 

 Errant" and "Triton", have brought many fresh fadts into 

 notice, and furnished new ground for its discussion.
