are necessary for the comprehension of the biological results. In the preparation of 

 the hydrographical summary Mr. Helland-Hansen has assisted the Committee. 

 II. The second section considers the distribution of the plankton eggs; the account 

 is based on the special papers of Damas, Redeke and Schmidt. 



Damas' paper deals specially with the material collected by the Danish, German, 

 English and Norwegian investigations from the region east of Great Britain. 



Redeke's paper considers the Dutch material from the Southern North Sea, chiefly 

 south of 55° N. L. 



Schmidt's paper treats of all the material from west of Great Britain. The second 

 section likewise discusses the drift of the eggs, larvae and young fishes. 



III. The growth of the older stages, their age and migrations form the subject of the 

 third section, on the basis of the papers by D'Arcy Thompson, Borley, Damas and 

 Helland-Hansen. 



D'Arcy Thompson's work gives the results of the Scottish statistics, chiefly for 

 the Northern North Sea, which was specially considered as Committee A's region. 



Borley describes the results of the English marking experiments on cod in the 

 Western North Sea. 



In Helland-Hansen's paper is considered the extensive material on the measure- 

 ments of fishes collected by the research-steamers, and Damas reports in his paper 

 on the results obtained from the age determinations, which in many ways throw 

 light on the matters discussed in the other papers. 



IV. The fourth section gives in conclusion a review of all the results, which are ot 

 special importance for the comprehension of practical fisheries questions. 



A Draft of this General Report was sent to the members of the above Committee
