ich was a smal Line of a
somewhat lighter part; and below that again, Southwards, was the great
black _Belt c_. Between that, and e, the other smaller black Belt, was a
pretty large and bright _Zone_; but the middle d, was somewhat darker than
the edges. I perceiv'd about 3^{h.} 15^{m.} near the middle of this, a very
_dark round Spot_, like that represented at g, which was not to be
perceiv'd about half an hour before: And I observed it, in about 10.
minutes time to be gotten almost to d, keeping equal distance from the
_Satelles h_, which moved also Westwardly, and was joyn'd to the Disk at i,
at 3^{h.} 25^{m.} After which, the Air growing very hazy, and (as appeared
by the _Baroscope_) very light also (in weight) I could not observe it: So
that it was sufficiently evident, that this black Spot was nothing else,
save the shadow of the _Satelles h_, Eclipsing a part of the Face of
Jupiter. About two hours before, I had observed a large darker spot in the
bigger _Belt_ about k, which in about an hour or little more (for I did not
exactly observe the time, nor draw the _Figure_ of it) moving Westwards,
disappear'd. About a week before, I discover'd also, together with a Spot
in the _Belt c_, another Spot in the _Belt e_, which kept the same way and
velocity with that of the _Belt c_. The other three _Satellites_ in the
time of this Eclipse, made by the _Satelles_, were Westwards of the Body of
_Jupiter_; appearing as bright through the Tube, as the Body of _Jupiter_
did to the naked Eye, and I was able to see them longer through the Tube,
after the day-light came on, than I was able to see the Body of _Jupiter_
with my naked eye.

_A late Observation about Saturn made by the same._

[Illustration]

_June_ 29 1666. between 11. and 12. at night I observed the Body of
_Saturn_ through a 60. foot Telescope, and found it {247} exactly of the
shape represented in the _Figure_ R. The _Ring_ appear'd of a somewhat
brighter Light than the _Body_; and the black lines a a, crossing the Ring,
and b b crossing the Body (whether Shadows or not, I dispute not) were
plainly visible: whence I could manifestly see, that the _Souther_-most
part of the Ring was on _this_ side of the Body, and the _Northern_ part,
behind, or covered by the Body.
