Mercury came to move along the other, as I found it to 
do at 3 1 ' i' 1 6" T. app. But RefraBion comr-afting 
this Difference of Declination about y Seconds (the 
Sun being then but about n° high) 1 concluded that 
the Centers of the Sun and Mercury , were truly in the 
fame Parallel of Declination at -g" 3' T. app. proxme. 
At JVanfted in Effex, my worthy Collegue, the Rev. 
Mr. James Bradly , Savilian Profeffor of AJtronomy , 
obferv’d with the Hugenian Telefcope , of above 120 
Foot long, the total lmmerfion, or mteriour Contact 
ofthe Limbs, at 2 h 2.6'4 AT. aq. that isi' 41 3 
T. app. twelve Seconds later than I found it at Green- 
wich 1 moll of this Difference being due to the Diffe- 
rence of our Meridians. And applying the Micrometer 
to that vaft Radius , he meafured the Diameter of the 
Tlanet 10" 45 At i h 48' 57" he found the Dif- 
ference of Declination between the fouthern Limbs of 
the Sun and Tlanet by the Micrometer , in a fifteen 
Foot Tube, to be 15' 19". Wherefore, allowing, the 
obferv’d Semidiameter of the Tlanet, and the Refrac- 
tion, the faid Difference was nearell 15^ 30 , and con- 
fequently Mercury more foutherly than the Sun s 
Center in relpedt of Declination o r 45 • 
Mr. George Graham , in Flect-fireet , London , ob- 
ferv’d the tar ft Impreffion on th qShh s Limb at 2A 41 / 
al'T. app. and at 2 h 42' 19" Mercury was intirely 
within the Disk. At 3'’ 6 ' 4i"he meafur’d with a Mi - 
crometer, in a twelve Foot i ube, the Diftanct. of his 
Center from the nearell Limb of the Sun 2 ' 13^. And 
avain, at 3 h 25 ' 24” their Diltance was found }' 57". 
At 2 h ’ 34' 43 " he meafur’d the Difference of Declina- 
tion, from the northern Limb of the Sun 1 4 ^ 5 7 / 
which, corrected by RefraBion, becomes 15-' 4", that 
is, 1 1 n 11 more northerly than the Sun’s Center.
