Winter-observations at Pitlekaj.
Some of these observations, which concern the saltness of
the ice, the efflorescence of Rossol salt and the appearance of
salt brines on the surface of the ice-floes are discussed in the
foregoing paper. In the following table are enumerated some
determinations of the temperature and spec, gravity of the
sea-water beneath the ice. 1 The titrations were made on
board the ship.
