344 PETTERSSON, SIBERIAN SEA. 



Thus the constitution of the water in the deeper strata 

 and at the bottom was fouiid to be almost imchanged in 1875, 

 76 & 78, and yet we know that, from a nautic point of view, 

 the condition of the Kära Sea was very different in 1876 from 

 in 1875 or 1878. 



I next wish to call attention to the important fact, that 

 the same constitution of the deeper water-strata with regard 

 to saltness and temperature also prevails in that part of the 

 Barentz Sea west of the Waigatch and Novaya Zemlya, as may 

 be seen from the following observations by the Swedish expe- 

 dition, 1875, and the Holland, 1881.
