same _Author_,
concerning _New Thermometrical Experiments and Thoughts_, as also, with an
Exercitation about the _Doctrine of the Antiperistasis_: In the former
whereof is _first_ proposed this _Paradox_, That not only our Senses, but
common Weather-glasses, may mis-inform us about Cold. _Next_, there are
contained in this part, New Observations about the deficiencies of
Weather-glasses, together with some considerations touching the New or
_Hermetrical_ Thermometers. _Lastly_, they deliver another _Paradox_,
touching the cause of the Condensation of the Air, and Ascent of water by
cold in common Weather-glasses. The latter piece of this part contains an
Examen of _Antiperistasis_, as it is wont to be _taught_ and _proved;_ Of
all which there will, perhaps, a fuller account be given by the Next. {10}

_An Account of a very odd Monstrous Calf._

By the same Noble person was lately communicated to the _Royal Society_ an
account of a very Odd Monstrous Birth, produced at _Limmington_ in
_Hampshire_, where a Butcher, having caused a Cow (which cast her Calf the
year before) to be covered, that she might the sooner be fatted, killed her
when fat, and opening the Womb, which he found heavy to admiration, saw in
it a Calf, which had begun to have hair, whose hinder Leggs had no Joynts,
and whose Tongue was, _Cerberus_-like, triple, to each side of his Mouth
one, and one in the midst: Between the Fore-leggs and the Hinder-leggs was
a great Stone, on which the Calf rid: the _Sternum_, or that part of the
Breast, where the Ribs lye, was also perfect Stone; and the Stone, on which
it rid, weighed twenty pounds and a half; the outside of the Stone was of
Grenish colour, but some small parts being broken off, it appeared a
perfect Free-stone. The Stone, according to the Letter of Mr. _David
Thomas_, who sent this Account to Mr. _Boyle_, is with Doctor _Haughteyn_
of _Salisbury_, to whom he also referreth for further Information.

_Of a peculiar Lead-Ore of _Germany_, and the Use thereof._

There was, not long since, sent hither out of _Germany_ from an inquisitive
Physician, a List of several _Minerals_ and _Earths_ of that Country, and
of _Hungary_, together with a _Specimen_ of each of them: among which there
was a kind of _Lead-Ore_ which is more considerable than all the rest,
because of its singular use for _Essays_ upon the _Coppell_, seein
