Investigations on the plaice: general report. Preliminary brief summary.

The 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 It will probably also be necessary to take into consideration new and hitherto unpublished material, which will necessitate further delay in the completion of the work.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 resumé 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. In English and German.
