“ (hort of reaching the limb of Venus. Out of the 
“ i8 that were taken, 14 of them correfpond fo well 
“ that I am convinced they may be depended upon. 
“ The 4th which 1 have fet down, and only one 
“ other, which will be found omitted, differ fome- 
“ thing from what they ought to be; which might 
“ eaiily happen, either from any midake in noting 
“ the time, or in reading the ‘vernier of the micro- 
meter, or not fixing it exadly in the direction of 
“ the n^areftdiftance of the limbs ; tho’ great care was- 
“ taken in this part, by fweeping it con flantly round 
“ to try the truth of the contadfs that were formed. 
The mealurcs intended to be taken in chords- 
“ parallel tg the equator, are very near the truth, con— 
iidering that, ii> letting the micrometer to, that di- 
redlion, we had only the truth of the polar axis to- 
“ depend on, which was confi:ru<ded haflily to an- 
*'• fwer the purpofe of the. day,, and was not exadly 
true, as a Imajh mot on of the ragk- work that railes- 
or depreffes.the telefcopc was foinetimes neceffary 
to keep the Sun in the field. Three of thefe mea- 
“ fures, parallel to the equator, agree with each- 
other, and with all the reft pf the micrometer ob- 
“ lervations, on fuppofing the chord in which they 
“ were taken inclined half a degree to the plane of 
“ the equator. . The fourth of thefe meafures is Hill 
“ more nearly parallel to the equator,, but, diverges a 
'* little the other way. Thefe chords are delineated
