The wind kept between the S.W. and S.E., on the 19th and 20th, afterward, it veered to the E., N.E., and N. The night between the 20th and 21st, an eclipse of the moon was observed as follows, being then in the latitude of 22° 57-1/2' S.:
The latitude and longitude are those of the ship, at 8 h 56 m a.m., being the time when the sun's altitude was taken for finding the apparent time. At the beginning of the eclipse, the moon was in the zenith, so that it was found most convenient to make use of the sextants, and to make the observations by the reflected image, which was brought down to a convenient altitude. The same was done at the end, except by Mr King, who observed with a night telescope. Although the greatest difference between our several observations is no more than fifty seconds, it, nevertheless, appeared to me that two observers might differ more than double that time, in both the beginning and end. And, though the times are noted to seconds, no such accuracy was pretended to. The odd seconds set down above, arose by reducing the time, as given by the watch, to apparent time.
I continued to stretch to the E.S.E., with the wind at N.E. and N., without meeting with any thing worthy of note, till seven o'clock in the evening of the 29th, when we had a sudden and very heavy squall of wind from the N. At this time we were under single reefed topsails, courses, and stay-sails. Two of the latter were blown to pieces, and it was with difficulty that we saved the other sails. After this squall, we observed several lights moving about on board the Discovery, by which we concluded, that something had given way; and, the next morning, we saw that her main-top-mast had been lost. Both wind and weather continued very unsettled till noon, this day, when the latter cleared up, and the former settled in the N.W. quarter. At this time, we were in the latitude of 28° 6' S., and our longitude was 198° 23' E. Here we saw some pintado birds, being the first since we left the land.
