COUNCIL — JULY 1905 14 
for his generous cooperation in Irish waters, and hopes that this important addition 
to the international work may be continued in the future. 
Il. The Bureau is requested, to prepare maps and sections of the average 
salinity from the hydrographical data obtained and to publish these together with 
information as to the variations from the average. 
III. The International Council resolves, that the surface observations which 
include salinities determined by titration and which hitherto have been worked up 
only for the surface maps in the Bulletin shall also be published in tabular form 
in Part A of the Bulletin. Mr. Martin Knupsen is requested to prepare as a 
specimen a cartographic representation of all the surface observations, utilizing the 
individual values or the mean values for suitable small areas (according to Winp’s 
method) or both methods, and when possible to include this in the Bulletin. 
IV. The International Council resolves, that observations in deepwater made 
at times between the seasonal cruises should be included in the Bulletin. The 
discussion of the hydrographical data is to be extended so as to include variations 
occurring between the fixed periods of observation. The observations in deep- 
water made at certain lightships to be designated by the Bureau are also to be 
included, provided that the salinity is determined by titration. 
V. The International Council requests the Bureau to enter into communica- 
tion with the “Deutsche Seewarte” and with other institutions, as also with private 
investigators, with the view of obtaining from them surface observations of tem- 
perature and salinity determined by titration. 
VI. The International Council requests the representatives of the participating 
states to endeavour to arrange for hydrographic cruises between the dates of the 
regular seasonal cruises, either according to the complete programme or with the 
understanding that the regular seasonal cruises shall be carried out with as little 
modification as possible. Mr. Martin Knupsrn is requested to undertake the necessary 
correspondence with the gentlemen responsible for the hydrographical work in the 
various countries. 
The discussion on these resolutions was then opened; after a few explanatory 
remarks they were accepted unanimously. 
Under Head 6* of the Agenda (Investigation of Water-samples with 
regard to Gas-contents etc.) Professor Psrrerssox said he wished to withdraw
