Council shall have authority to make any necessary alterations in these 

 lines, or in the regions where each nation is to work. 



The special points are to be decided by the respective nations, and 

 when once chosen the subsequent observations are to be repeated at 

 the same points. 



The special instructions for the work will also be given by the 



respective nations, and the communications as to the extent and the 



nature of the observations shall take place through the Central Bureau 



(see C). 



X. 



§ 17. It is desirable to supplement these investigations by making 

 use of regular liners, light-ships, etc., and coast-stations for the purpose 

 of taking temperature observations and collecting samples of sea-water 

 and plankton. These observations are to be taken not only in the 

 typical months, but also during the intervening periods.

Delimitation of Areas. 

 I. 



§ 1. It is recommended that each of the nations taking part in the 

 international investigation should undertake the biological study of a 

 definite area to be decided on as in the case of the hydrographical work 

 and to correspond with the divisions adopted for that purpose. 



The following is suggested as a preliminary division : — 



A. North Sea south of 54° N. 



1. From 2° E. eastward to Borkum Reef: Holland and Belgium. 



2. From Borkum Eeef to the Elbe : Germany. 



3. From 2° E. westward to the British coast, including the English 

 Channel : Great Britain and Belgium. 



B. North Sea, from 54° N. to 58° N. 



1. From 2° E. eastward to Jutland and the Naze: Germany and 

 Denmark. 



2. From 2° E. westward : Great Britain. 



C. North Sea, north of 58° N., and North Atlantic to about 62° 

 N. (the Faroes) : Great Britain, Norway, and Denmark.
