than at Greenwich, on account of parallax. I then 
calculated what would be the effect of parallax at each 
place, fuppoling the Sun’s parallax to be 9 leconds ; 
and found that the time of the internal contadf would 
be accelerated i'.i 6", 63 at Greenwich, and retarded 
W 31', 09 at the Cape: the whole effedt of parallax 
therefore is . But the difference in time ’ 
as found by obfervation, is only 7' • 2 4 // • and there- 
fore the difference by calculation is to the differ- 
ence by obfervation, as the affumed parallax is to the 
true parallax on the day of the tranfit, which by this 
obfervation is 8 // ,543. The parallax refulting hom 
each obfervation will be found in the following table, 
which will be fufficiently explained by the foregoing 
example.
