Friday, 24th. First part, Calm; Middle, light breezes; latter, fresh breezes and hazey. P.M. had several Azimuths, all of which gave the Variation less than 4 degrees East, but they were a little doubtful on account of the Rowling of the Ship. What winds we have had this day hath been from the Eastward, and are the first we have had from that Quarter since we left the Latitude 58 degrees 46 minutes. Wind calm, East-North-East and East-South-East; course North 42 degrees 45 minutes West; distance 79 miles: latitude 43 degrees 37 minutes South, longitude 107 degrees 6 minutes West.
Thursday, 23rd February, 1769
Thursday, 23rd. Little wind and Calm, and some Lightning, a thing we have not seen for some time past, and therefore suppose not common in these Seas in high Latitudes. Variation 5 degrees 34 minutes East. Wind North-West, calm; course North 30 degrees East; distance 13 miles; latitude 44 degrees 35 minutes South, longitude 105 degrees 52 minutes West.

Saturday, 18th. Fresh gales all this day. The weather Variable, sometimes fair and Cloudy, other times hazey, with drizzling rain. Saw some Birds nearly as big as Albetrosses; they were all black, with Yellow Beaks. Wind South-West by West; course North 32 degrees 30 minutes West; distance 140 miles; latitude 44 degrees 50 minutes South, longitude 99 degrees 7 minutes West.

Thursday, 16th February, 1769
Thursday, 16th. The first part of this day had fresh Gales and Cloudy; in the night thick hazey weather with heavy squalls of wind and rain, which obliged us to close-reef our Topsails. In the morning and all the forenoon had strong gales and cloudy weather, and very heavy Seas from the South-South-West, one of which broke upon the Quarter and carried away the Driver Boom. Wind North-West, West, and South; course North 74 degrees West; distance 97 miles; latitude 48 degrees 0 minutes South, longitude 94 degrees 25 minutes West.
Wednesday, 15th February, 1769
Wednesday, 15th. Little wind and Cloudy the most part of this day. Variation per Azimuth in the Evening 12 degrees East, and in the morning both by an Amplitude and an Azimuth 11 degrees East. A.M. Shifted the Mainsail, Mizen, Fore, and Main topsail.

Monday, 13th February, 1769
Monday, 13th. The first part of these 24 Hours, moderate breezes and Cloudy; remainder, fresh Gales and cloudy. P.M saw a great many Albetrosses and other Birds about the Ship; some were all white and about the size of Teal. Took several Observations of the sun and moon, the result of which gave 90 degrees 13 minutes West Longitude from Greenwich. The Variation of the Compass by the Mean of several Azimuths 17 degrees East. The Longitude by account is less than that by Observation, 37 minutes, which is about 20 Miles in these high Latitudes, and nearly equal to the Error of the Log line before mentioned. This near Agreement of the 2 Longitudes proves to a Demonstration that we have had no Western Current since we left the Land. Wind West, Northerly; course North 75 degrees West; distance 35 miles; latitude 49 degrees 35 minutes, longitude 90 degrees 37 minutes.
Sunday, 12th February, 1769
Sunday, 12th. First and Middle parts, fresh gales and cloudy; latter, little wind and clear. Having for some time past generally found the Ship by Observation to the Northward of the Log, which is not owing to a Current as I at first imagined, but to a wrong Division of the Log line, being 2 1/2 feet in each Knot–but this is now rectified. Wind South-West by South; course North 48 degrees West; distance 113 miles; latitude 49 degrees 41 minutes South, longitude 89 degrees 36 minutes West.

Tuesday, 7th February, 1769
Tuesday, 7th. A fresh breeze and dark cloudy weather, with some showers of rain; the wind, varying from West to North by West, obliged us to Tack several times. Wind North-West by West, West by South; course North 20 degrees West; distance 46 miles; latitude 54 degrees 40 minutes South, longitude 82 degrees 54 minutes West.

Saturday, 4th February, 1769
Saturday, 4th. Fore and Middle parts, little wind and dark cloudy weather; latter, fresh Gales and Cloudy with some rain. P.M. had a Boat out and Shott several sorts of Birds, one of which was an Albetross as large as a Goose, whose wings when Extended measured 10 feet 2 inches; this was grey, but there are of them all White except the very tip end of their Wings. Another sort, in size between an Albetross and a large Gull, of a grey Colour, with a white Spot above their Tail about the Breadth of one’s hand, and several other sorts.

Wednesday, 1st February, 1769
Wednesday, 1st. First part, fresh Gales; latter, light Airs and Cloudy; P.M. found the Variation by several Azimuth to be 24 degrees 53 minutes East. At Noon sounded, but had no ground with 240 fathoms of line; hoisted a Boat out to try if there was any Current, but found none. The weather was such as to admit Mr. Banks to row round the Ship in a Lighterman’s Skiff shooting birds. Wind, South-East by East, South-South-East, East; course, North-West by West; distance, 106 miles; latitude 58 degrees 46 minutes South, longitude 78 degrees 42 minutes West.
Tuesday, 31st January, 1769
Tuesday, 31st. First part moderate and Cloudy, with some rain; in the night, little wind and Calm; towards Noon, fresh Gales and Cloudy. Between 7 and 8 p.m., being then in the Latitude of 60 degrees 10 minutes, which was the farthest south we were, and in the Longitude of 74 degrees 30 minutes found the Variation of the Compass by the mean of Azimuth to be 27 degrees 9 minutes East. At 3 a.m. wind at East-South-East, and Moderate breeze. Set the Steeringsails, and soon after 2 Birds like Penguins were seen by the Mate of the Watch. Wind West-North-West, calm, East-South-East, South-South-East; course North 71 degrees West; distance, 55 miles; latitude 59 degrees 46 minutes South, longitude 75 degrees 54 minutes West.
Monday, 30th January, 1769
Monday, 30th. Fore part, fresh Gales and Squally with Hail and rain, remainder moderate and Cloudy. At 6 a.m. loosed the 2nd reef out of the Topsails and set Top-gallant Sails. At 11 Longitude per 3 sets of Observations of the sun and moon, 1st set 73 degrees 38 minutes 15 seconds; second set 73 degrees 25 minutes 45 seconds; and 3rd, 73 degrees 19 minutes 30 seconds; the mean of the whole is 73 degrees 27 minutes 50 seconds West, and 35 minutes less than the Longitude by Dead reckoning, which is only 6 Leagues in this Latitude, and therefore not worth taking notice of. Latitude per Observation 60 degrees 4 minutes South. Wind West by North and West-North-West; course, South 33 degrees West; distance, 76 miles; latitude 60 degrees 4 minutes South, longitude 74 degrees 10 minutes West.
Sunday, 29th January, 1769
Sunday, 29th. First and Latter parts, fresh Gales and Squally, with flying Showers of rain and Hail; the Middle, strong Gales with heavy Squalls and showers of rain. At 8 p.m. took 2nd Reef Topsails, at 6 a.m. Close reefd the Foretopsails and took in the Mizen Topsl, and at 10 set it again and let the reef out of the Fore top-sails. Wind, West Northerly; course South-West; distance, 79 miles; latitude 59 degrees 0 minutes South, longitude 72 degrees 48 minutes West.
Saturday, 28th January, 1769
Saturday, 28th. Fresh Gales the most part of this day; first and Middle parts cloudy; latter, clear with a Sharp cold air. At 2 p.m. saw the land, bearing North, distant about 8 Leagues; it made in 2 Hummocks, and appeared to be an Island, which I take to be the Isle of Diego Ramirez. It lays in the Latitude of 56 degrees 38 minutes South and Longitude 68 degrees 47 minutes West from Greenwich. Found the Variation this Evening to be 22 degrees East. A.M. had 3 sets of Observations of the sun and moon, which gave the Longitude 69 degrees 7 minutes 15 seconds West. The Longitude of the Ship at Noon by the Observation is 69 degrees 24 minutes, from which take 1 degree 48 minutes, the longitude made from Cape Horn, the remainder is 67 degrees 36 minutes, the Longitude of the Cape, which is 52 minutes less than the result of Yesterday’s Observations. This difference may arise partly from the Observations and partly from the Ship’s runs; the mean of the 2 gives 68 degrees 2 minutes and 68 degrees 24 minutes, the Longitude of the Cape from the Observations taken at Strait Maire 136 degrees 26 minutes/2 = 68 degrees 13 minutes West from Greenwich. The Longitude of Cape Horn being deduced from no less than 24 Observations taken at no very great distance from the Cape, and on both sides of it, and when the Sun was both to the East and West of the Moon; for in this case the Errors arising from the Observations are most likely to Correct one another. Wind, North and West by North to North-West by West; course, South 39 degrees West; distance, 80 miles; latitude 58 degrees 4 minutes South, longitude 70 degrees 1 minute West.
Friday, 27th January, 1769
Friday, 27th. First part, moderate breezes and thick Hazey weather; the Middle, fair and Cloudy; and the Latter, fresh Gales with some rain. At 8 a.m. took two Setts of Observations of the sun and moon; the first gave 68 degrees 15 minutes; the second, 68 degrees 9 minutes; the Mean of the 2 is 68 degrees 12 minutes West. The Longitude of the Ship at Noon by these Observations is 68 degrees 42 minutes less 14 minutes, the Longitude made from Cape Horn, equal to 68 degrees 28 minutes, the longitude of Cape Horn according to the Observation. A Great many large Albetrosses about the Ship. Wind, South-West, West and North; course, South and West; distance, 32 miles; latitude 57 degrees 2 minutes South, longitude 68 degrees 27 minutes West.
Thursday, 26th January, 1769
Thursday, 26th. Fresh Gales and thick Hazey weather, with small rain. At 2 p.m., the weather clearing up a little, saw Cape Horn bearing West-South-West, distance about 6 leagues, and from which I take my departure. Its Latitude and Longitude have before been taken notice of. Wind South-West by West to West-North-West; course South 15 degrees West; distance, 63 miles; latitude 56 degrees 57 minutes South; longitude 68 degrees 13 minutes West; at noon, Cape Horn North, 58 miles.
