Sunday, January 1st, 1769. First and Latter part, fresh breezes and Clear weather; in the Middle, light Airs and Calm. At Noon, longitude in per 4 Sets of Observations between the sun and moon 61 degrees 8 minutes 28 seconds west. The Difference between the least and Greatest of these sets was 8 minutes, and the mean of 2 differs from the Mean of the whole but 32 seconds. The Longitude by account carried on from the last Observations exactly agree with these Observations. Saw a great number of small Whales about the Ship. Wind South to West-South-West; course South 36 degrees West; distance 39 miles; latitude 43 degrees 35 minutes South; longitude 61 degrees 8 minutes 28 seconds West.

The first part of this day a Genteel gale and Clear weather; middle, Squally, with Lightning and rain, and some showers of Large Hail Stones; towards Noon a Steady fresh breeze and Clear weather. At noon longitude in by 3 sets of Observations between the sun and moon 61 degrees 7 minutes 45 seconds, which is 43 seconds to the Eastward of yesterday's Observations.

At Noon saw several Birds of a light Grey Colour, like Pidgeons, but smaller; these are of the Mother Carey's kind. Longitude per Observation 61 degrees 29 minutes 45 seconds, which is 22 minutes to the westward of Yesterday, but the ship hath made 41 minutes, Consequently there is an Error of 19 minutes, which is not to be supposed to be in the Log in one Day's run; but, be it which way it will, it is not great. Wind West, Southerly; course South 11 degrees; distance 122 miles; latitude 47 degrees 17 minutes South, longitude 61 degrees 29 minutes 45 seconds West.

Wednesday, 4th. First part, genteel breeze and Clear; latter, fresh gales, with heavy squalls of wind and rain, which brought us under our courses and main topsails close reefed. Soon after noon saw the appearance of Land to the Eastward, and being in the Latitude of Peypes Island, as it is lay'd down in some Charts, imagined it might be it.* (* Pepys' Island, placed on charts, from a report by Captain Cowley in 1683, about 230 miles north of Falkland Islands, and long imagined to exist. It was eventually recognised, after the discovery of Cowley's manuscript Journal, that Cowley had sighted the Falklands.) Bore down to be Certain, and at 1/2 past 2 p.m. discovered our Mistake, and hauld the Wind again. At 6 sounded, and had 72 fathoms black sand and mud. Variation 19 degrees 45 minutes East. Wind West-North-West to South-West by South; course South 30 degrees East; distance 76 miles; latitude 48 degrees 28 minutes South, longitude 60 degrees 51 minutes West.
