In order to find the error of the micrometer (if 
any), Jupiter’s diameter was meafured to the right 
and to the left j and Mr. P.ittenhoufe afterwards 
took the trouble cc mealure the diameter of a white 
painted circle both ways ten times. This work was 
performed early in the morning before fun-rife, when 
the air was ftiil, and tree from all tremulous mo- 
tion j the refult of which, on a mean of thofe to the 
right, and a like mean of thofe to the left, was an 
error of adjuftment for the micrometer of 
to be fubtradled ; which was accordingly allowed 
for in the redudlion of all the micrometer mea- 
fures. 
Thus we have given a full and faithful account 
of our work. We could have witlied to have 
comprized it in lefs room. Had our latitude and 
longitude been well fixed, as they had been at 
Philadelphia, by able mathematicians, beforehand, 
a confiderable part of our work might have been 
faved. But as it was necefiary to fiiew, that fuch 
pains have been taken in thefe material articles, that 
they may be depended on ; and as we had op- 
portunities
