A similar spot was founcl by a Swedish expedition in 1896 

 at 79° 6' K, 5° 17' E. See Pettersson and Ekman (6, p. 5). 



As to salinity, most of the Gulf Stream samples are iying 

 between 35.00 and 35,25 %o, thus corresponding to the salinity of 

 the western part of the Gulf Stream as this is defined by Mr. 

 Martin Knudsen. See Knudsen and Ostenfeld (4, p. 32). 



It seems to me that the most interesting hydrographic fact 

 derived from the observations of the two captains is the great ex- 

 pansion of the Gulf Stream in 1898 with a considerable rise of 

 temperature. and a similar one in 1S99. accompanied by a depres- 

 sion of temperature. 



Prof. Pettersson has in a series af interesting works drawn 

 attention to the influence of the Gulf Stream variations on the 

 Scandinavian climate and the winter fisheries of cod and herring. 

 The discussion of the said influence on the cod migrations I hope 

 to take up in a later paper; I will here only mention that the 

 influence of the Stream on the ice conditions in the Arctic Ocean 

 most probably have effects on the catehing (of seal). By convers- 

 ing and corresponding with sealers I have got the impression 

 that a retrogression of the ice in the Jan Mayen lield (as in 1898) 

 is unfavourable. The same can certainly be said about the neid 

 north of Spitsbergen.
