the ligament detached from the Sun’s limb, I turned 
my eye to the clock, to catch the minute, and to be 
fatisfied that I was right in my counting of the fe- 
conds. And when I returned my eye to my telef- 
cope, w'hich was before or not later than the 55th 
fecond, I found that the thread of light between the 
limb ot Venus and the limb of the Sun had feniible 
breadth, and the'fhape of the Planet was perfedly 
circular. Mr. Jackfon reckoned the internal. contact 
at 7^' 21' 51'’', by our regulator. He judged of it as 
I did, by the detachment of the ligament, which he 
faw, as well as I, from the Sun’s limb. My regulator, 
when it was hrft fet a-going, feemed to gain on 
Mr. Hornfby’s obfervatory clock for fome hours 
(the pendulum, perhaps, not being' come to its na- 
tural fwing). But on Friday evening, about a 
quarter after eight, it was too flow for Mr. Hornfby’s 
clock 13". On Saturday, half an hour after noon, 
it was 1 8'', 9 too flow. And Saturday evening, at 
9^ 30', it was 27'' too flow j and on Sunday morn- 
ing, about nine o’clock, it was 32'''' or 33^' too 
flow. So that at the time of the internal contaifl it 
, was 25'''' I or 26''' too flow for Mr. Hornlby’s ob- 
fervatory clock. ’ ■ ■ 
I was much furprized, upon comparing notes with 
Mr. Hornlby, to find that he had judged the internal 
contact 14" I or 15'' earlier than, I did. 
The foregoing narra.tive of what I faw,,^I have 
drawn up June 8th, having not converfed with any 
other obfervers, except Mr. Hornlby and Mr. Jack- 
fon, and Mr. Maflcelyne, whom I met in the flreet 
this day, and talked with him very curforily. And 
that my account may be purely of what I faw, as it
