HYDROGR. SECTION — FEBR.-MARCH 1906 ( 39 ) 
Under Head 2 Mr. Knupsen submitted to the Section the charts of surface- 
temperatures for the North Sea drawn up in accordance with Resolution III of 
the July 1905 Meeting of the International Council (Procés-Verbaux p. 15). The 
Section examined the work critically and recommended the continuance of the 
charts according to the plan shown in the Bulletin for July—August—Septem- 
ber 1905. 
Under Head 3 the Section after examining the printed schemes proposed 
agreed to their preparation and publication, as also to the other changes in Parts A, 
B and C of the Bulletin. 
Head 4 was postponed. 
Outside the agenda, Prof. Winp proposed that average values for the tempe- 
ratures should also be prepared in charts and sections from the material so far 
published in the Bulletin. Mr. Knunsen offered to make an attempt in this direc- 
tion and to lay the result before the Section at the next opportunity. The Section 
agreed to this proposal. 
Prof. Perrersson submitted to the Section a treatise by Prof. V. Bierknes with the 
remark that it contained a proposal, to which he wished to refer at the next sitting. 
Dr. Mr stated that the British Government desired that the procedure to be 
adopted in drawing up a report on the results of the International Investigations 
should be considered. He thought it of importance that the Hydrographical Sec- 
tion should seriously consider this matter. 
The Section agreed to deal with the subject at the next sitting. 
The next sitting was arranged for Thursday, March 1st at 10 a.m. with the 
following agenda: | 
1. The hydrographical investigations of the Danish research-steamer “Thor” 
during the year 1906 and the question whether the seasonal eruises between the 
Faeroes and Iceland might in future be omitted. 
2. Determination of bottom-temperatures by means of telegraph cables. 
3. Proposal of Prrrersson in relation to the treatise of Bjerknes on the 
isobar surfaces of the atmhosphere and the sea. | 
4, Proposal of Mit. concerning a report to the participating governments. 
5. Report of the Special Committee appointed on July 18th 1905 to consider
