This dangerous commotion we attributed to the current by which for several days we had been carried to the south-westward, but which had during the last day changed its course to the north-westward, and which was running at the extraordinary rate of sixty-eight miles per diem, or nearly three miles an hour, in direct opposition to the wind.
April 15.The temperature of the surface of the sea fell so rapidly from 73° to 61°, that I concluded we were approaching a body of ice, and some indications in the sky favoured this belief. We did not however see any, and before midnight the temperature had again risen to 67°, so that, if its fall were occasioned by ice, we had probably passed it in the dark.
April 16.At noon we were in lat. 41° 24′ S. and long. 25° E., and detected another change in the current, it having carried us N. 75 E., twenty-two miles during the last twenty-four hours; and again we found a gradual depression in the temperature of the sea from 68° at 1h. a.m. to 58° at noon, without any
