these curious searches in Antiquity,
did not hinder this great _Virtuoso_ from discharging the duties of his
place with much assiduity, and with so much ability, that he hath had the
reputation of one of the greatest _Civilians_ of his Age.

But that, which is most of all surprizing to many, is, that with all that
strength of understanding, which was requisite to make good these rare
qualities, lately mentioned, he had so polite and delicate parts, that he
composed _Latin_, _French_, and _Spanish_ Verses with the same elegancy, as
if he had lived in the time of _Augustus_, and passed the greatest part of
his life at the Courts of _France_ and _Spain_.

More particulars will perhaps be mention'd of the Works of this Rare
person, when all things, that he hath publish'd, shall be recovered, and
when liberty shall be obtained of his Worthy Son, to impart unto the World
the rest of his Writings, hitherto unpublished.

_Extract of a Letter, lately written from _Rome_, touching the late Comet,
and a New one._

I Cannot enough wonder at the strange agreement of the thoughts of that
acute French Gentleman, Monsieur _Auzout_, in the _Hypothesis_ of the
Comets motion, with mine; and particularly, at that of the _Tables_. I have
with the same method, whereby I find the motion of this Comet, easily found
the Principle of that Author's _Ephemerides_, whi
