Whereas notice has been taken in _Num._ 6. of these _Transactions_, that there was some difference between those two deservedly celebrated Philosophers, _Monsieur Hevelius_ and _Monsieur Auzout_, concerning an Observation, made by the former of them, on the 8/18 of _February_ 1665. & that thereupon some Eminent _English_ Astronomers, considering the importance of the dispute, had undertaken the examination thereof; it will, 'tis conceived, not be unacceptable to such, as saw those Papers, to be informed, what has been done and discerned by them in that matter. They having therefore compared the Printed Writings of the two Dissenters, and withall consulted the observations made with _Telescopes_ at home, by some of the most intelligent Astronomers amongst them, who have attentively observed the Position of that _Comet_ to the _Telescopical_ stars, that lay in its way; Do thereupon Joyntly conclude, that, whatever that Appearance was, which was seen near the _First Star_ of _Aries_, by _Monsieur Hevelius_ (the truth of whose relation concerning the same, they do in no wise question) the said _Comet_ did not come neer that _Star_ in the left _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_.
