Appendix I 



(Proposal regarding an International Hydrographieal Laboratory). 



To the Bureau of the 



International Council for the Investigation of the Sea. 



I hereby beg to suggest that an international hydrographieal laboratory 

 should be instituted, as such a laboratory could, in my opinion, be of very great 

 service to the Hydrographers, even though it were arranged on a much smaller 

 scale than the former laboratory in Christiania. 



The principal objects of the laboratory should in my opinion be the following: 



1) To facilitate the obtaining of hydrographieal apparatus and utensils. 



2) The testing of hydrographieal apparatus and furtherance of uniformity in 

 the instruments and methods employed. 



In this connection I beg to further add the following remarks: 

 I frequently receive requests from hydrographers to furnish them with hydro- 

 graphical instruments and to test same, and can in such case only give them 

 advice as to the maker of the various instruments. It also happens, that the hydro- 

 graphers send in their orders so late, that it is impossible to furnish the instru- 

 ments required within the time-hmit given, and the stock of hydrographieal mate- 

 rials for use on their expedition is thus incomplete. I would therefore suggest, 

 that the laboratory should keep a stock of certain instruments, as for instance: 

 thermometers of reversion, Pettersson-Nansen water-bottles with thermometers, 

 meter-wheels, bottles for storing water samples for chlorine or oxygen-titrations 

 apparatus for titrations and standard fluids, Ekman's and Jacobsen's current-meter, 

 Pettersson's registering current-meter, drift-bottles for the surface and deeper 

 layers. It is also of great importance to have such parts of instruments as are 

 frequently lost. Such a depot would certainly be a convenience to the hydro- 

 graphers of the international organisation, but certainly not indispensable. It 

 would however, in my opinion, be of great importance to provide the means of 

 properly equipping such other expeditions, as might require to be furnished with
