HYDROGRAPHICAL SECTION — JULY 1905 ( 32 ) 
be enlarged by tables, which would contain all the surface-observations the salinity 
of which had been determined by the titrimetrical method. This extension should be 
made at once, and Docent Knupsen was invited to investigate in detail, what 
the expense would be of a cartographic representation either of the separate 
observations or of the averages according to the method of Prof. Winp or of 
both, and to report on the matter at the next meeting of the Council (Resolu- 
tion III). | | 
In reply to a question from Prof. Branpr it was resolved, that the publication 
of the surface observations hitherto made should be left to the resp. countries. 
On the proposal of Prof. Wın it was resolved, that the Bureau should be asked to 
enter in relation with the “Deutsche Seewarte”, in order to obtain surface-observations 
(data regarding the temperature and the salinity) from that institute (Resolution V). 
A long discussion then took place regarding the modification and extension 
of the seasonal cruises. 
Great stress was laid upon the desirability of hydrographical observations in 
the interval between the seasonal cruises, especially in relation to the fisheries 
investigations. The continuation of the discussion was adjourned so as to permit 
of consultation with the biologists. 
Prof. Branpt proposed that it be permitted in future to replace, if desired, 
the inexact signs in the Bulletin for the frequency of the plankton by data indi- 
cating the occurrence and non-occurrence. In that case a brief remark on the 
frequency, and on the principal forms etc. might be appended to the tables. 
The meeting did not think it fell within its competency to decide on this 
proposal and referred it to the Bureau. 
The meeting adjourned at 5:20 p.m. 
Third Sitting: Thursday July 20 at 10:45 a. m. 
Vice-President Orro Perrersson in the chair. 
Present also: Exman, Gitson, Hsornt, Homen, KnıpowitscHh, Knunsen, Krimuet, Minn, Nansen,

Secretary: Martin KnuDsen. 
The President opened the discussion between the hydrographers and biolo- 
gists. The gentlemen present thought desirable to modify in future the periodical 
cruises in the Norwegian Sea and in the northern part of the North Sea, in order 
to concentrate the international hydrographical work on questions of more direct 
importance and bearing on the practical fisheries investigations. It seemed especially 
necessary to bring the Norwegian and Scottish periodical cruises and other hydro-
