observed
nothing, but what confirms Monsieur _Christian Huygens de Zulichem_ his
Systeme of that Planet, published by that worthy Gentleman in the year,
1659. {3}

The _Third_, respects _Jupiter_, wherein _Campani_ affirms he hath observed
by the goodness of his Glasses, certain _protuberancies_ and
_inequalities_, much greater than those that have been seen therein
hitherto. He addeth, that he is now observing, whether those sallies in the
said _Planet_ do not change their scituation, which if they should be found
to do, he judgeth, that _Jupiter_ might then be said to turn upon his
_Axe_; which, in his opinion, would serve much to confirm the opinion of
_Copernicus_. Besides this, he affirms, he hath remarked in the _Belts_ of
_Jupiter_, the shaddows of his _satellites_, and followed them, and at
length seen them emerge out of his Disk.

_A Spot in one of the Belts of Jupiter._

The Ingenious Mr. _Hook_ did, some moneths since, intimate to a friend of
his, that he had, with an excellent twelve foot Telescope, observed, some
days before, he than spoke of it, (_videl._ on the ninth of _May_, 1664,
about 9 of the clock at night) a small Spot in the biggest of the 3
obscurer _Belts_ of _Jupiter_, and that, observing it from time to time, he
found, that within 2 hours after, the said Spot had moved from East to
West, about half the length of the Diameter of _Jupiter_.

_The Motion of the late Comet praedicted._

There was lately sent to one of the _Secretaries_ of the _Royal Society_ a
Packet, containing some Copies of a Printed Paper, Entituled, The
_Ephemerides_ of the _Comet_, made by the same Person, that sent it, called
_Monsieur Auzout_, a _French_ Gentleman of no ordinary Merit and Learning,
who desired, that a couple of them might be recommended to the said
_Society_, and one to their _President_, and another to his Highness Prince
_Rupert_, and the rest to some other Persons, nominated by him in a Letter
that accompanied this present, and known abroad for their singular
abilities and knowledge in Philosophical Matters. The end of the
Communication of this Paper was, That, the motion of the _Comet_, that hath
lately appeared, having been praedicted by the said _Monsieur {4} Auzout_,
after he had seen it (as himself affirms) but 4 or 5 times: the _Virtuosi_
of _England_, among others, might compare also their Observations with
