During the next two days it blew a gale from the N.W., and for the first time we had rain instead of snow, the temperature having risen to 37. As we were now approaching Bouvet Island, we rounded to every night, lest we should either run upon, or pass it in the dark.

At 8 p.m. we were in latitude 54° 8′., and longitude 4° 36′ E.; only fifty-eight miles from the island, as placed on the Admiralty chart.
