This table explains itfelf. If we, therefore, take 
the mean of the Sun’s parallax ariling from each of 
thofe fixteen total durations, it will be found = 8", 
48, and if we rejedt the obfervations of number 
7th, 8th, 9th, 10th, 1 2th, 13th, and 14th, which 
differ the moft from the reft, the mean of the nine 
remaining ones gives the Sun’s parallax = 8", 55, 
agreeing, to a furprizing exadtnefs, with that found
