noteable for the failure of certain of the winter-fisheries. 



The statements rendered in this paper will appear sufficient to remove all doubts 

 regarding the existence of a near connection between hydrographie, météorologie and 

 biologic phenomena. It is desirable therefore, that the statistical investigations of the 

 fisheries of our seas pay careful attention to the annual variation of hydrographie and 

 plankton-biologic conditions which occur in these seas.
