Here we ſee alſo, (as I have noted even now) that ſhould the
Authour conſent to aſſign the diſtance of 32. Semidiameters for
the true height of the Star, the correction of thoſe his 10. workings,
(I ſay 10. becauſe the ſecond being very high, is reduced to the
height of 32. Semidiameters, with 2. minutes correction) to make
them all to reſtore the ſaid Star to that diſtance, would require ſuch
a reduction of Parallaxes, that amongſt the whole number of ſub
ſtractions they ſhould make more than 756 m. pr. whereas in the
5. calculated by me, which do place the Star above the Moon, to
correct them in ſuch ſort, as to conſtitute it in the Firmament,
the correction onely of 10. minutes, and one fourth ſufficeth.
Now adde to theſe, other 5. workings, that place the Star
ciſely in the Firmament, without need of any correction at all,
and we ſhall have ten workings or indagations that agree to place
it in the Firmament, with the correction onely of 5. of them (as
hath been ſeen) but 10. m. and 15 ſec. Whereas for the
on of thoſe 10. of the Authour, to reduce them to the altitude of
32. ſemidiameters, there will need the emendations of 756
nutes in 836. that is, there muſt from the ſumme 836 be
cted 756. if you would have the Star elevated to the altitude of
32. ſemidiameters, and yet that correction doth not fully ſerve.
The workings that immediately without any correction free the
Star from Parallaxes, and therefore place it in the Firmament,
and that alſo in the remoteſt parts of it, and in a word, as high
as the Pole it ſelf, are theſe 5. noted
