general view of the members was that, for the main tables, the values for each

Programme of the Atlantic Slope Committee. 



1) Portugal. As far as the means at their disposal permit, it would be 

 desirable for Portugal to undertake the following work: — 



a) An océanographie section from south of Cape Vincent to the coast of Morocco, 

 as often as possible, and more particularly in January. 



b) An océanographie section from Lisbon to the Azores, and further a special 

 monthly station from the surface to 1000 m by the Azores. 



2) France. It would be of benefit that the following work were carried 

 out by France:

 these cruises, that will be conducted by naturalists, will depend on circumstances 

 and cannot be fixed beforehand.

4. England. (M.B.A.). It is desirable that the researches undertaken in 

 the western part of the Channel be continued in the widest measure possible.

2) A study of the causes which bring about the migrations of these fishes. This
