[ *75 ] 
The weather was more favourable at your Lord- 
lhip’s own obfervatory at Shirburn-Caffle, where the 
Reverend Mr. Hornfby, Fellow of Corpus-ChrifH 
College in Oxford, attended, to affift Mr. Phelps and 
Mr. Bartlett, your own obfervers. Mr. Hornfby has 
favoured me with a copy of the obfervations there 
made ; and writes, that though the morning feemed. 
very unpromifmg, yet the clouds began to difperfe 
about half an hour after five, moving flowly towards 
the eaff. He then made many obfervations of the 
differences of Venus and the fun’s limb in right: 
afcenfion and declination,, in the lame manner which 
I ufed at the Royal Obfervatory, the fky free from 
clouds, and the air tolerably clear. I fha-11 not at 
prefent lay thefe obfervations, or my own, or Mr.. 
Green’s, before your Lordfhip and the Society, as the 
fhcrtnefs of the time will not permit me to examine 
how well they correfpond with each other, or what- 
degree of exadnefs may be depended upon from 
them. 
The continual fwift motion of dying clouds, of 
different denfities, over the difk of the fun, were no 
imall prejudice to our obfervations at Greenwich, 
till the end of the tranfit was approaching, when it 
was tolerably clear, a fmall hazmefs only remaining. 
We obferved the internal contad of Venus- with the 
fun’s limb, Mr. Green having taken off the micro- 
meter with the two feet refledor, Mr. Bird, mathe- 
matical inftrument- maker in the Strand, with a re- 
fledor of i § inches focal length, of his own making, 
and myfelf with the refrador, the telefcopes ufed by- 
Mr. Bird and myfelf magnifying about jj times, 
that by Mr. Green 120 times, June yth, 1761, at
