18. Experiments and Observations touching the Coldness and Temperature of the Air.
19. Of the strange Effects of Cold.
20. Experiments touching the weight of Bodies frozen and unfrozen.
21. Promiscuous Experiments and Observations concerning Cold.
This Treatise will be dispatched within a very short time, and would have been so, ere this, if the extremity of the late Frost had not stopt the Press. It will be accompanied with some Discourses of the 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.
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.
