It has then been found that at depths between 350 and 3000 metres 
the values of the salinity must have been between the following upper 
and lower limits, on the dates mentioned:

If the bottom-water of the North Polar Basin with temperatures 
below zero, has a nearly uniform salinity, like that of the Norwegian 
Sea, this salinity must consequently, according to the observations, be 
between 35°08 °/,. and. 3511 % “As there seems fo be no probable 
reason to doubt these derterminations it appears at present, until new 
investigations shall have been made, necessary to assume that the salinity 
of the bottom-water of the North Polar Basin is about 35:10 "/00. 
On November 30 and December 2, 1895, Dr. Blessing bottled 
several water-samples from depths between 150 and 900 metres in the 
North Polar Basin. These samples were brought home, and the specific 
gravity of five of them carefully determined by Mr. Hercules Tornøe 
with the Sprengel pyenometer!. If the salinities be computed by Knud- 
sen’s Tables from the specific gravities thus obtained the following values 
for salinity and density, of the samples from 800 and 850 metres are 
obtained:
