REFACE 



1 he General Report on the investigations of the International Council for 

 the study of the Sea on the plaice question will, on account of the extensive nature 

 of the work, yet require some time to fully complete. It will probably also be 

 necessary to take into consideration new and hitherto unpublished material, which 

 will necessitate further delay in the completion of the work. I have therefore, at 

 the request of the Central Council, compiled the following short resume of the most 

 important conclusions hitherto arrived at in the Report. It is however, impossible 

 here to state in full detail the grounds on which these conclusions are based, or 

 the sources from which they are obtained. 



Copenhagen, iS'h September 1911. 



Heincke.
