over the Sun , on Saturday Morning , 6 th 
June 1761, at Savile-Houfe, about 8 " of 
rime Weft of St. Paul j *, London. 
Read June u, XT IS Royal Highnefs the Duke of 
8 I York, being defirous of obferving 
the rare phenomenon of Venus’s paflage over the 
dilk of the fun, I had the honour of being com- 
manded by his Royal Highnefs, to attend him on 
that occafion at Savile-houfe, which was a place the 
moft proper for that obfervation, on account of its 
remarkable elevation above all the neighbouring 
buildings, and confequently above the grofs vapours 
of the town. 
In obedience to thefe orders, on Friday, 5th June, 
I carried thither the indruments proper for this ob- 
fervation, together with an adronomical clock, made 
by Mr. Shelton, and the fellow of that which was 
lad made for the Royal Obfervatory at Greenwich, 
and which dands in the trandt-room, and went to 
the faid houfe on Saturday morning, at four o’clock, 
in company with the Reverend Dr. Blair, and Dr. 
Bevis, and immediately put the indruments in order. 
The indruments, made ufe of on this occafion, 
were a reflecting telefcope of 1 8 inches focus, with 
a heliofcope adapted to it, and having a field of more 
than the fun's diameter, proper for fhewing Venus 
on the fun’s did:, with great eafe and fatisfaCtion ;
