heaving down by, there being no other method to come at a Ship's bottom, as the Tides doth not rise above 6 or 7 feet. At the New and full Moon it is high Water at that time about 8 o'clock, when the Land and Sea breezes are regular, but when they are not the Course of Tides are alter'd. The Sea breeze begins to blow about 10 or 12 o'clock, and continues until sunset, when it dies away and is succeeded by the land breeze, which continues most part of the night. From a little after sunrise until the Sea breeze sets in it is generally Calm, and is then the Hotest and most Disagreeable part of the whole day. CHAPTER 2. RIO JANEIRO TO TAHITI.

At noon the Observed latitude 26 Miles to the Southward of the Log, which I believe is chiefly owing to her being Generally steer'd to the Southward of her Course. Yesterday being Christmas Day the people were none of the Soberest. Wind North; course South-West; distance 158 miles; latitude 40 degrees 19 minutes South, longitude 54 degrees 30 minutes West. Tuesday, 27th. Fresh breezes and Hazey with Squalls which Obliged us during the Night to take in the small Sails and 2 reefs in the Topsails which were let out in the Morning. Wind northerly; course South 50 degrees West; distance 123 miles; latitude 41 degrees 38 minutes South, longitude 56 degrees 15 minutes West. Wednesday, 28th. First part Strong Gales and Cloudy, which Obliged us to get down TopGallant Yards. At 8 p.m. it blew a Storm of Wind with Rain which brought us under our Mainsail with her Head to the Westward. Sounded 50 fathoms, fine brown Sand; 40 at midnight had 40 fathoms, the same bottom. At 4 a.m. had 46 fathoms Coral Rock.

P.M. loosed all the Reefs out, and got Topgallant Yards a Cross. Variation per Azimuth 16 degrees 12 minutes, per Amplitude 16 degrees 32 minutes; Mean of the Two 16 degrees 22 minutes East. Between 9 and 10 a.m. took 7 sets of Observations between the sun and moon to find the Longitude of the Ship. Each set Consists of three Observations; the Mean of the whole gave 59 degrees 18 minutes 34 seconds West of Greenwich. The result of each set was as follows: viz., 1st set, 59 degrees 8 minutes; Second, 59 degrees 21 minutes; Third, 59 degrees 34 minutes; Fourth, 59 degrees 17 minutes; Fifth, 59 degrees 11 minutes 45 seconds; Sixth, 59 degrees 19 minutes 30 seconds; and the Seventh, 59 degrees 20 minutes 45 seconds. The greatest differance between any two--viz., the first and third--is but 26 minutes, and the mean of these two differ from the mean of the whole only 2 minutes 26 seconds. This shews to what degree of accuracy these observations can be made even by Different Persons, for four of these were made and computed by Mr. Green and the rest by myself. The Longitude given by the Ship, reckoning from the last Observation 5 Days ago, differs only 8 Miles from the Observation, which shews that we have not been in any Currents. Soundings from 40 to 47. Wind North-Easterly; course South 46 degrees 30 minutes West; distance 81 miles; latitude 41 degrees 45 minutes South, longitude 59 degrees 37 minutes West. Friday, 30th.

Wind variable;
