s inclined to the _Vertical_, sometimes
_Perpendicular_ to the _Horizon_, and at last _Parallel_; the _Convexe_
part respecting the _Heaven_, and the _Concave_, the _Horizon_. By the
crossing (_so they go on_) of the {297} _Horns_ with the _Angles of
Inclination_, it will be easie to those, that have exactly observed them,
and that are skill'd in the higher _Astronomical_ Calculations, to compute
the _true Place_ of the _Moon_ in her _Orbite_, that so it may be compared
with that of the _Tables_, and with that, which has been observ'd in other
places, for the more precise determinating of the _Difference_ of
_Meridians_ (that being the way, esteem'd by _Kepler_ the most certain) and
for making a good Judgment of the defect or exactnesse of the Celestial
_Tables_.

Then they observe, That the _Beginning_ and the _Middle_ of this _Eclipse_
hapned to be in the _North Eastern Hemisphere_, and the _End_, in the
_South-Eastern_. The _first Contact_ (as 'twere) of the two Disks was
observ'd in the _Superior Limb_ of the _Suns Disk_ in respect to the
_Vertical Line_, and in the _Inferior_ in respect to the _Ecliptick_: But
the _Middle_, and the _End_ were seen in the _Superior Limb_, in respect
both to the _Vertical_ and the _Ecliptick_: And (what to this Author seems
extraordinary) both the _Beginning_ and the _End_ of this _Eclipse_ hapned
to be in the _Oriental_ part of the Suns Disk.

Lastly, they take notice, that by their Observations it appears, that there
is but little exactness in all the _Astronomical Tables_, predicting the
_Quantity_, _Beginning_ and _Duration_ of this Eclipse; Those of
_Lansbergius_ importing, That the Obscuration should be of 10. dig. 48';
those of _Ricciolo_, of 9. dig. 1'; and those of _Kepler_, of 7. dig. 30'.
16": Again, that the _Duration_ should be of 2h. 2'. Lastly, The
_Beginning_ did anticipate the _Ricciolan Tables_ by 5 _minuts_, the _End_
by 23; and the _Middle_, almost by 11. In the mean time the Author notes,
that the _Rudolphin Tables_ come nearest to the Truth; and withal assures
the _Reader_ of the goodnesse of the _Instruments_ employed in his
_Observations_, and of the singular care, he, together with his skilful
Assistants, took in making them.
