in 
gravity of the samples thus taken was carefully determined by Mr. Jakob 
Schetelig with the Hydrometer of Total Immersion. The salinity was 
determined by Mr. Leivestad, by Titration (Mohr). The values obtained 
by the two methods agree on the whole very well, as is seen in the 
Table below. Makaroffs values thus obtained, may consequently be 
assumed to be very accurate, and are in several respects important}. 
The results of the determinations of the samples from this part of the 
sea are therefore here given in detail.

Makaroff's Stations 77, and 83 are evidently in the channel or de- 
pression communicating with the North Polar Basin? (see Fig. 1, p. 24). 
Here at depths about or greater than 200 metres, there is warm water 
trust these simple green bottles, he also sent some other samples, taken simultaneously, 
in very fine glass-bottles with glass-stoppers; but these samples gave all of them higher 
salinities, indicating that evaporation had taken place.
