The numbers [pointed with blue] in sections IV, V & VI, 

 which represent the saltness in p. c. of the surface-water, reveal 

 to US another very important fact, viz. that the great fresh-ivater 

 current of the Kära Sea, derived from the Ohl and Yenisei rivers, 

 does not reach farther eastivard than Cape Tcheljuskin. The diluted 

 water at the siirface, north of the Taimur peninsuhi, is of course 

 due to an admixture of river-water, but this water does not 

 belong to the Obi and Yenisei, but to the great Siberian river- 

 system east of the Taimur land. For in case the fresh- 

 Avater current from the Kära Sea reached beyond the Taimur 

 peninsula, we ought to find the saltness of its water continu- 

 ally increasing along its whole course. Instead, it reaches its 

 maximum at Cape Tcheljuskin. The following series is the result 

 of the regular observations of the saltness of the water at the 

 surface between Port Actinia and the Chatanga Bay (see sec- 

 tions IV, V, VI on plate 24 & 25)

This fact is the more remarkable as we raight rather 

 anticipate the contrary. It can be seen most unmistakably 

 from the sections VII, VIII, IX that the currents from the 

 rivers Chatanga, Olonek, Anabara, Lena, Indigirka, Kolyma 

 etc. . . are always deviating to the east; consequently we should 

 expect that the upper-current of the Kära Sea, after rounding 

 the northern and eastern capes of the Taimur coast, would 

 penetrate into the Siberian Sea. From the other side there 

 is no current of river-water along the east side of the Taimur 

 land, which could directly neutralize the former. From section 

 VI we see, that the outflow from the Chatanga bay takes an 

 easterly and southerly direction. Towards the north it is 

 limited by a »wall» of relatively cold and salt water. I think 

 the problem can be explained as follows: The average niveau 

 of the Siberian Sea, east of the Taimur peninsula, is raised by
