And ſo many ſemidiameters are contained in the line B C, to
which one being added for the line A B, we ſhall have little leſſe
than 61. ſemidiameters for the two lines A B C; and therefore
the right diſtance from the centre A, to the Star C, ſhall be more
than 60. ſemidiameters, and therefore it is ſuperiour to the Moon,
according to Ptolomy, more than 27. ſemidiameters, and according
to Copernicus, more than 8. ſuppoſing that the diſtance of the
Moon from the centre of the Earth by Copernicus his account is
what the Author maketh it, 52 ſemidiameters.
With this ſame
working, I find by the obſervations of Camerarius, and of
ſius, that the Star was ſituate in that ſame diſtance, to wit,
what more than 60. ſemidiameters.
Theſe are the obſervations,
