Though the weather continued fair, the sky, as usual, was clouded.
However, at nine o’clock the next morning, it was clear, and we were
enabled to observe several distances between the sun and moon. The mean
result of which gave 39° 30ʹ 30ʺ east longitude. Mr. Kendal’s watch, at
the same time, gave 38° 27ʹ 45ʺ, which is 1° 2ʹ 45ʺ west of the
observations; whereas, on the 3d instant, it was half a degree east of
them.
In the evening I found the variation, by }

Gregory’s compass, to be }

of Dr. Knight’s }
And by another of Dr. Knight’s 28 34 0
Our latitude at this time was 63° 57ʹ, longitude 39° 38-1/2ʹ east.
The succeeding morning, the 15th, being then in latitude 63° 33ʹ south,
the longitude was observed by the following persons, viz.
Myself, being the mean of six distances } 40° 1ʹ 45ʺ E.
of the sun and moon }
Mr. Wales, ditto 39 29 45
Ditto, ditto 39 56 45
Lieutenant Clerke, ditto 39 38 0
Mr. Gilbert, ditto 39 48 45
Mr. Smith, ditto 39 18 15
----------
Mean 39 42 12
----------
Mr. Kendal’s watch made 38 41 30
Which is nearly the same difference as the day before. But Mr. Wales and
I took each of us six distances of the sun and moon, with the telescopes
fixed to our sextants, which brought out the longitude nearly the same
as the watch. The results were as follows:—By Mr. Wales 38° 35ʹ 30ʺ, and
by me 38° 36ʹ 45ʺ.
