The boat was kept moored to the bottom some time to ascertain if there was any current, but it was not perceptible. The line was then cut, not being sufficiently strong to draw the weight up again.

In the afternoon the temperature and specific gravity of the sea at various depths was tried. The temperature of the surface at the time being 43°; at 150 fathoms, 42°; at 300 fathoms, 41°; at 450 fathoms, 40°, and at 600 fathoms, 39.8°: the specific gravity being the same throughout the whole depth as at the surface, 1.0274, at 43°. A piece of sea-weed, the first we had seen since leaving the antarctic seas, was passed during the afternoon.
