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. Little wind, and sometimes Calm; the first part Clear
weather, remainder Foggy and Hazey. Soundings from 44 to 49 fathoms; Grey
sandy Bottom. Caught both this Morning and last Night a great Number of
insects. Some were upon the Wing, but the greater part were upon the
water, and many of these alive and of such sort as cannot fly far; and
yet at this Time we could not be less than 30 Leagues from Land. Wind
variable; course South 30 degrees West; distance 54 miles; latitude 42
degrees 32 minutes South, longitude 60 degrees 15 minutes West.

Saturday, 31st. Cloudy weather, with some Lightning and a few showers of
rain. Variation 18 degrees 36 minutes East. Soundings from 46 to 50
fathoms; fine dark sand. Wind South-Easterly; course South 18 degrees
