the plankton and the corresponding chemical properties of the water is also 

 going on. 



In connection with the work in May and July 1922 were taken samples for 

 determination of plankton. 



France. Recherches quotidiennes depuis 1920 au bateau-phare de Sandettie 

 (Mer du Nord). Triage et déterminations au Laboratoire de Boulogne-sur-Mer. 



Holland. A series of nanoplankton samples from the southern North Sea 

 collected and preserved after Gran's method in March and April 1914 was partly 

 worked up. No new plankton material was collected during the last year. 



c. Statistics. 



Belgium. Le travail de la statistique du marché au poisson d'Ostende ainsi 

 qu'il est dit plus haut a été interrompu par des difficultés survenues au sein du per- 

 sonnel de la minque. Cependant les quantités de poissons débarqués au cours de 

 l'année sont annotées et pourront être tabulées, si l'utilité de ce travail tardif se 

 fait encore sentir. De plus la nomination toute récente d'un excellent directeur 

 de ce marché nous garantit pour l'avenir le fonctionnement d'un service statistique 

 de premier ordre. 



Denmark. The general statistics of catch are collected and published yearly 

 for each of the principal waters round Denmark: The North Sea, Skagerak, Katte- 

 gat, Belt Sea, Sound, Western Baltic and True Baltic. Besides this a great material 

 is collected upon which more detailed statistics can be worked out, e. g. catch per 

 month, catch per fishing day, catch in each of the depth areas or rectangular areas etc. 



England. The system of rectangular areas on the plan recommended by the 

 Statistical Committee had already been put into operation for demersal fish in 

 the North Sea at the beginning of 1920, but the areas used are based on Mercator's 

 projection. The method of nomenclature recommended by the Committee has been 

 adopted and extended to regions outside the North Sea. As from Jan. 1st, 1922, 

 pelagic fish are being tabulated both in the North Sea and outside in the new rect- 

 angular areas. An attempt is being made to extend the system outside the North 

 Sea for demersal fish also. 



Scotland. At a meeting of the Interdepartmental Conference held in London 

 on October 6th, 1921, it was decided to adopt, provisionally, certain fundamental 

 amendments to the proposals brought forward and carried at the last meeting of 

 the International Council at Copenhagen in July 1921. 



As now amended, the affected paragraphs in the original report (Proc. Verb. 

 . XXVII, p. 44) read as follows:— 



A 1) That each region to be divided into squares is known and referred to by the 

 origin of reference which will be the latitude and longitude of the bottom
