It appears alfo by his calculation, that the time of 
the internal contadt was accelerated 30", and the laft 
contadt 18", by parallax. The iaternal contadt, 
therefore, as feen from the center of the Earth, was 
at 2i h s' 2 %"> and the external conta( ^ was at 
2i h 23' 25", and the egrefs of the planet’s center at 
2i h H' 33" „ f J 
From the time of the planet’s paffage over the edge 
of the Sun’s difk, as feen from the Earth’s center, the 
author very accurately determines the planet’s diame- 
ter to be Sl"\' , , 
The egrefs of the center of Venus, as deduced 
from the pofition of its path, and from the other ele- 
ments, as related above, differs near two minutes 
from the obferved time, when corredted by parallax, 
and reduced to the Earth’s center. This difference 
is entirely to be attributed to an error in the motion 
of Venus in longitude, which, perhaps, could not be 
deduced with fufficient accuracy from thefe obferva- 
tions, and from a fmall error in fome of the other 
elements j all which the author might have taken,^ 
with the utmoft accuracy, from the tables either of 
Dr. Halley or M. Caffini. Perhaps alfo, fome part 
of this difference might arife from our ignorance of 
the true quantity of the Sun’s parallax. 
Hitherto our author has given us thofe elements, 
which might immediately be determined from his 
obfervations \ the following are deduced from the 
tables. From the the motion of Venus in latitude, 
it may readily be colledted, that the planet was in its 
node on June 5, at I4 h 55' 9". The place of the 
Sun at that time, according to the tables of the Abbe 
De la Caille, was in n 14° 59 ' 5 't* and th ?
