are to be understood _literally_, seeing that the _Church_ may make a
contrary declaration, no man ought to scruple to follow the _Hypothesis_ of
the _Earths motion_, but only forbear to maintain it in _publick_, till the
prohibition be called in. But to return to the matter in hand, this Author,
upon all these observations and relations of _Cassini_ and _Campani_, doth
find no reason to doubt any more of the excellency of the Glass used by
them, above his; except this difference may be imputed to that of the
_Air_, or of the _Eys_. But yet he is rather inclined to ascribe it to the
goodness of their Glasses, and that the rather, because, he would not be
thought to have the vanity of magnifying his own; of which, yet he
intimates by the by, that he caused one to be wrought, of 150 _Parisian_
feet; which though it proved none of the best, yet he despairs not to make
good ones of _that_, and of far greater Length.

__Signor Campani's_ Answer: and Monsieur _Auzout_'s Animadversions
thereon._

The other part of this _French Tract_, conteining _Campani_'s Answer, and
Mr. _Auzout_ his _Reflections_ thereon, begins with the pretended _Shadows_
of the _Ring_ upon _Saturn_, and of _Saturn_ upon the _Ring_. Concerning
which, the said _Campani_ declareth, that he never believed them to be
_shadows_, made by the _Ring_ upon the _Disk_ of _Saturn_, or by the body
of _Saturn_ upon the _Ring_, but the _Rimms_ of these bodies, which being
_unequally_ Luminous, did shew these appearances. In which Explication,
forasmuch as it represents, that the said _Campani_ meant to note only the
_Inequality of the Light_, which, _he saith_, his Glasses did discover, Mr.
_Auzout_ does {76} so far acquiesce, that he only wishes, that his own
Glasses would shew him those differences. Next to the Objection, made by
Monsieur _Auzout_, against Signor _Campani_, touching the Proportion of the
Length of the _Ring_ to its breadth, _Campani_ replyeth, that the Glasses
of Monsieur _Auzout_, shew not all the particulars, that his do, and
therefore are unfit for determining the true Figure and breadth of the
apparent _Ellipsis_ of the _Ring_. To which M. _Auzout_ rejoyns, that he is
displeased at his being destitute of better Glasses, but that it will be
very hard for the future to convince _Campani_ touching the _Proportion_ of
the _Ring_, seing that the breadth of the _Ellipsis_ is always diminishing,
altho
