Here follows the feries of my determinations of the 
longitude, during my voyage, delivered in an extradt 
of my fea journal. The firft column contains the 
day of the month ; the fecond, the latitude ; the 
third, the longitude, which I deduced from my ob- 
fervations of the Moon, reduced to the neareft noon ; 
the fourth (hews the longitude per account, kept in 
the ufual manner ; the fifth gives the difference be- 
tween the third and fourth columns, and expreftes 
how much the longitude deduced from the obferva- 
tion of the Moon is weft of the longitude per ac- 
count; the laft column (hews, whether the diftance 
of the Sun from the Moon, or diftance of what ftar 
from the Moon, . was obferved.
