by the
water hath, all the while it is descending, a clear passage through;
whereas, as soon as the Bucket is pulled upwards by the Line F, the
resistance of the water to that motion beats the Bucket downward, and keeps
it in the posture G, whereby the Included water is preserved from getting
out, and the Ambient water kept from getting in.

By the advantage of which Vessel, it may be known, whether sea water be
Salter at and towards the bottom, then at or near the top: Likewise,
whether in some places of the sea, any sweet water is to be found at the
bottom; the _Affirmative_ whereof is to be met with in the _East Indian_
Voyages of the industrious _John Hugh Van Linsckoten_, who page 16 of that
Book, as 'tis _Englished_, records, that in the _Persian Gulph_, about the
Island _Barem_, or _Baharem_, they fetch up with certain Vessels (which he
describes not) water out of the sea, from under the salt-water, four or
five fathom deep, as sweet, as any Fountain water. {150}

_Of the Judgement of some of the _English_ Astronomers, touching the
difference between two learned men, about an Observation made of the First
of the two late _Comets_._

[Sidenote: _By _Telescopical_ Stars are understood such, as are not seen,
but by the help of a Telescope._]

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 th
