CH. l] THE EXPLORATION OF THE SEA 29 



Forms of fishing gear capable of giving quantitative results do 

 exist but the consideration of these will occupy us further on. 

 In the present chapter I have dealt with the exploration of the 

 sea so far as this may be studied by the exact methods of physical 

 and chemical science ; and with the ordinary collecting methods of 

 biology, which so far aim mainly at the discovery of the forms of 

 life which are present in the sea, and with the broader facts of the 

 distribution of these.
