We invariably found the temperature of the water increase with a southerly gale, 
and decrease as we approached the ice. At Spitzbergen, in August, the flood tide 
which came from the southward, was 3* warmer than the ebb ; the former being 3 7*, 
the latter 34. 0

About 10 leagues 
distant from Spitz- 
bergen. The ship 
in general closely 
beset with ice. 
* The above are the means between those observations most to be relied on. The 
Specific Gravities were taken with great care while the ship was beset in ice, and had 
no motion, with an hydrostatic balance, made for me by Newman, of Lisle-street.
