makes the diameter of the fun at right angles to the 
equator, with his micrometer, 31' 32" '. At 2 oh 12' 
apparent time, Mr. Hornfby, by one obfervation, 
makes the center of Venus north of the fun’s fouth 
limb in declination, 3' 26". The latitude of the ob- 
fervatory at Shirburn-Caftle is 51 0 3p' 22", being 
to the north of the Royal Obfervatory io' 43 11 . The 
difference of longitude between them has been deter- 
mined, by fome former obfervations, to be 4/ i" y 
that of Shirburn being to the weft. Thefe are all 
the obfervations which are come to my knowlege, 
and which I think, at prefent, worthy the attention 
of your Lordfhip, and the Royal Society. If the 
others fhould hereafter appear to be fo, they fhall be 
laid before you, by 
Your Lordfhip’s 
and their moft obedient 
humble fervant, 
Nathaniel Blifs.
