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 Muno­
sius, that the Star was situate in that same distance, to wit, some­
what more than 60. semidiameters. These are the observations,
and these following next after them the calculations.
