Directions for the hydrographical purposes during the seasonal cruises, the methods of treatment, and 

 Piani<ton during the preparation of the so called plankton protocols". 



the Seasonal 

 Cruises 



The November Bulletin began the publication of these results, and contained 

 plankton tables from Sweden (August and November), Denmark (November) and 

 from Holland (November). The tables for Finland and Norway (February) 

 appeared in the third Bulletin, and in the May number are also the tables for 

 Germany (May), England (February and May) and Scotland (May). 



Although the determination of the plankton collected during the seasonal 

 cruises occupies a considerable space of time, it seems c[uite possible that this 

 portion of the investigations — if the workers will just confine their attention to 

 what is really necessary — will also be accomplished within the period between 

 the seasonal cruises. 



Plani(ton col- 

 lected by mail- 

 steamers etc. 



Plankton samples have been collected in the North Sea, by the steamers 

 already spoken of, during the months selected for the investigations (August, No- 

 vember, February and May) in addition to those taken by the special research 

 steamers. Prof. P. T. Gleve has worked up the material thus collected, on 



the lines: 



Hebrides-Skagen 

 Orkneys- » 

 Shields- 



Glasgow-Skagen 

 Granton- , 

 Hamburg- , 

 Le Havre- , 

 The results of his investigation, as drawn up by him, are published in the 

 concluding number of the first annual volume of the Bulletin. 



Their Aim and 

 Object 



B. The Biological Investigations 

 As explained in the preliminary remarks to the Christiania programme of 

 investigations, the main object of the international cooperation to be kept in mind, 

 was the practical benefit of the fisheries and the obtaining of a scientific and 

 economically correct basis for international legislation. It became apparent, when 

 the preparations for working out the Christiania programme were in progress, in 

 the interval between the Christiania conference (May 1901) and the first meeting 

 of the Internationa] Council (July 1902), that the difficulty and the number of the 

 problems as well as the wide extension of the field of labour, made it obligatory 

 that attention should be concentrated on a few but important problems of economi-
