To these particulars, and others formerly imparted, his Excellency is
making more of the same nature; and particularly those of the Immersion of
the _Satellites_ of _Jupiter_.

We must not omit mentioning here, what he hath observed of _Halo_'s about
the _Moon_; which he relates in these words;

_Decemb._ 25. _Old Style_, 1666. In the Evening, here (vid. at _Madrid_)
was a great _Halo_ about the Moon, the _Semidiameter_ whereof was about 23
deg. 30 min. _Aldebaran_ was just in the _North-east_ part of the _Circle_,
and the two Horns of _Aries_ just enclosed by the _South-west_ of the
_Circle_, the Moon being in the _Center_. I note this the rather (_saith
he_) because five or six years ago, vid. _Novemb._ 21. _Old Style_, 1661.
an hour after Sun-set, I saw a great _Halo_ about the Moon of the same
_Semidiameter_, {391} at _Tangier_, the Moon being very near the same
place, where she was now.

_Publisher_, containing Observations about some _Insects_, and their
Inoxiousness, &c._

The Ingenious Author of this Letter, as he expresses an extraordinary
desire to see the _Store-house_ of _Natural Philosophy_, more richly
fraughted (a Work begun by the single care and conduct of the Excellent
Lord _Verulam_, and prosecuted by the Joynt-undertakings of the _R.
Society_) so he very frankly offers his Service in contributing some of his
Observations, and begins in this very Letter to perform his Offer. For,
Having taken notice of what was publisht in _Numb. 9. p. 161_. out of the
_Italian_ Philosopher _Redi_, vid. That Creatures, reputed Venomous, are
indeed no Poysons, when swallow'd, though they may prove so, when put into
Wounds: He, for confirmation thereof, alledges Examples of several Persons
well known to him (himself also having been an Eye-witness to some such
Experiments) who have frequently swallow'd _Spiders_, even of the rankest
kind, without any more harm than happens to Hens, Robin-red-breasts, and
other Birds, who make Spiders their daily Commons. And having made mention
of some men, that eat even _Toads_, he adds, that though a Toad be not a
Poyson to us in the whole; yet it may invenome outwardly, according to some
parts so and so stirr'd; an instance whereof he alledges in a Boy, who
