5. The 2d obfervation made at Greenwich being 
dubious, if the mean of the iff, 3d, 4th, and 5th, 
be taken at I9 h 48' 39", apparent time, at Green- 
wich, the obferved right afcenfion was 6' 5 2". 4, and 
the obferved declination 1 f 52". 4; from whence 
the vilible longitude was S' 6". 1, and the vilible la- 
titude if 4 // -3, from the fun’s center. The vilible 
ecliptic conjunction was, therefore, iy h 46' 17", ap- 
parent time, at Greenwich, with 9' 5 5 // -5 of vilible 
iouth latitude. The parallax of longitude, to be 
added, was 12". 6 ; and the parallax of latitude, to 
be fubtraCted, 17" .3, to give the true longitude and 
latitude from the fun’s center. The true ecliptic con- 
junction, therefore, was at I7 h 42' 2 8 // , apparent 
time, at Greenwich j when the true latitude was 
9 ' 32 "- 4 - 
I have omitted the computation of the longitude, 
latitude, and of the vifible and true conjunction from 
the internal contaCt, at Greenwich, and the difference 
of declination, as given in my laft letter ; becaufe 
there mull have been fome miftake in reading the 
numbers of the micrometer, or in fetting them, or 
the times, down : for they differ too much from all 
the above, which correfpond fo well with each other, 
(though made at different places, and with different 
inftruments) and give the true latitude, at the ecliptic 
conjunction, about 8 // lels, that we cannot lately de- 
pend upon them. 
If, therefore, we fuppofe the vilible ecliptic con- 
junction to have happened at 17** 45' 3", apparent 
time, at Greenwich, being the mean of the five fore- 
going deductions, where the greatelt difference is no 
.more than 2' 1 3" of time, or 8" of vilible longitude, 
with
