I (liall now produce, at one view, the means of 
the feveral determinations of the Sun’s parallax, by 
the before-mentioned three feveral methods, which 
will contain the fubftance of this whole paper. 
i m0 . The mean of 1 16 comparifons of 
the internal contacts obferved at places to 
the north of the Line only, gives the f 
Sun’s parallax — -J 
2 do . The mean of 2 1 comparifons of 
the internal contacts, with that at the 
Cape, gives the Sun’s parallax - - — - 
3 ti0 . The mean of 21 comparifons of 
the internal contadls with that at Rod- 
rigues, gives the Sun’s parallax - - — _ 
4 t0 . The mean of the comparifons of 
the total durations gives the Sun’s parallax 
5 t0 . The mean of the apparent leaft dis- 
tances of the centers compared with that 
meafured at Rodrigues, gives the Sun’s 
parallax - - — __________ 
6 t0 . The mean of the apparent leaf! dis- 
tances of the centers by computation from 
the total durations compared together, 
gives the Sun’s parallax - . 
The mean of thefe 6 means gives the 
Sun’s parallax - - — - - — _ — _ 
And if we rejedt the mean arifing from 
the comparifons of the total durations, 
which is the leaft certain, the mean of 
the other 5 means gives the Sun’s parallax. 
= 3. 565 
= 8. 56 
= 8.57 
— 8. 61 
= 8. 56 
= 8. 53 
} = 
8. 566 
8-557 
Thus
