_Ear_ of _Aries_, where the said M. _Hevelius_ supposes it to have passed,
but took its course neer the _Bright Star_ in its _Left Horn_, according to
_Bayers_ Tables. And since that the Observations of judicious both _French,
Italian, & Dutch_ Astronomers (as many of them, as are come to the
knowledge of the _English_) do in the main fully agree with theirs, they do
not at all doubt, but that, there being such an unanimous {151} consent in
what has been just now declared, & the Controversie being about _Matter of
fact_, wherein Authority, Number, and Reputation must cast the Ballance,
Mons. _Hevelius_, who is as well known for his Ingenuity, as Learning, will
joyn and acquiesce in that sentiment.

_Of a correspondency, to be procured, for the Finding out the _True_
distance of the _Sun_ and _Moon_ from the Earth, by the _Paralax_, observed
under (or neer) the same _Meridian_._

Seeing that the knowledge of this distance may prove of important Use, for
the Perfecting of Astronomy, and for the better establishing the doctrine
of _Refractions_, it is in the thoughts of some very curious Persons in
_England_, for the finding out the same, to settle a Correspondency with
some others abroad, that are understanding in Astronomical matters, and
live in places farr distant in _Latitude_, and under (or near) the same
_Meridian_.

To perform which, the following Method is proposed to be observed; _viz._
That at certain times agreed on by two Observatours, making use of
_Telescopes_, large, good and well fitted for this purpose, by a measuring
rod, placed within the Eye glass at a convenient distance, that it may be
distinctly seen, and serve for measuring small distances by minuts and
seconds (which is easie enough in large _Telescopes_) that, I say, each of
such observers, thus furnish't shall observe the visible way of the _Moon_
among the _Fixt Stars_, (by taking her exact distance from any _Fixt
Starr_, that lyes in or very near her way, together with the exact time of
her so appearing) and the then apparent Diameter of her Disk; continuing
these Observations every time for two or three hours; that so, {152} if
possible, two exact observations of her _Apparent_ place among the _Fixt
Stars_ being made, at two places thus distant in _Latitude_, and as near as
may be under the same _Meridian_, by these Observators concurring at the
same time, her true and exact distance may be
