We had the winds from the north-east with squalls and hazy weather, until the 29th, when it backed round to the westward again, and the weather became fair. After the time-keeper was taken from the Sirius, I kept an account of the ship's way by my own watch, which I had found for a considerable time, to go very well with Kendal's; I knew it could be depended on sufficiently to carry on from one lunar observation to another, without any material error; for although its rate of going was not so regular as I could have wished, yet its variation would not in a week or ten days have amounted to any thing of consequence; it was made for me by Mr. John Brockbank, of Cornhill, London, upon an improved principle of his own. The lunar observation, which I never failed to take every opportunity, and which Lieutenant Bradley also paid constant attention to, gave me reason to think, by their near agreement with the watch, that it continued to go well. On the 1st of December our longitude, by account, was 36 deg. 42' east; by the watch 36 deg. 48' east; and by distance of sun and moon 36 deg. 24' east: latitude 40 deg. 05' south, and the variation of the compass 29 deg. 40' west. For three successive days both Mr. Bradley and myself had a variety of distances, by which our account seemed to be very correct. I now determined (if I could avoid it) never to get to the northward of latitude 40 deg. 00' south, and to keep between that parallel and 43 deg. or 44 deg. south. After the 3d, I found, by altitudes taken for the watch, that we went farther to the eastward than the log gave us, and no opportunity offered for getting a lunar observation to compare with it until the 13th, when both Mr. Bradley and I got several good distances of the sun and moon, by which our longitude was 70 deg. 22' east, by the watch 70 deg. 07' east, and by account 67 deg. 37' east.
