Answer to Some Magnetical Inquiries, Proposed Numb. 23. of These Transactions, Pag. 423, 424

Answer to some Magnetical Inquiries, proposed Numb. 23. of these Transactions, Pag. 423, 424. The Queries were these. 1. Whether a Needle may be so toucht upon any Magnet, as not to point to the true North and South? &c. 2. Whether different Load-Stones, will give different directions? or, whether fainter or stronger touches, upon one and the same Magnet, will cause any Variation in the directions? &c. To these the Industrious Mr. Sellers returns this Answer: To the First; That he had often made tryal with many Needles touching them in each Hemisphere of the Stone, with all variety of wayes he could imagine, to find, if it were possible by that means to cause any of these Needles to vary in its direction but, that he alwayes found the contrary; all of them conforming to the Magnetical Meridian, and standing North and South, as other Needles, that were toucht upon the very Pole of the Stone. He adds, that some of these Experiments he tryed in London, when there was no Variation known. To the Second; 1. That, upon frequent tryals of touching Needles upon different Load-Stones, of several bignesses, as also of different vertue; the several Needles, touched upon these different Stones, gave all of them the same directions. This he thinks is confirm'd by all the Needles and Sea-Compasses, made in several parts of the World, and consequently touched upon several Stones of several Countries, yet all agreeing in this Magnetical Harmony, that they all give the same directions. 2. That having sometimes drawn a Needle only over the Pole of the Stone, within the Sphere of its vertue, without at all touching the Stone; it hath received the same directive quality from the Stone, as if it had been really toucht upon the Stone it self, though not altogether so strong, as if it had toucht the Stone. Again, that having toucht Needles upon the Stone, with faint strokes, and other Needles with stronger; all these Needles received the same effect from the Stone, both for strength and direction; he conceiving, that 'tis not the fainter or stronger touches upon the Stone, nor the multiplicity of Strokes, that varies the Needles strength or direction; but that the Nature of the Steel, whereof the Needle is made, and the Temper that is given thereunto, thereunto, causeth different effects, as to the strength it receiveth from the Stone; himself as having tryed all sorts of Steel, that he could possibly procure, and all the different Tempers he could imagine, for the most powerful receiving and retaining the vertue from the Load Stone; wherein he affirms to have fully satisfied himself, so that he can infuse such vertue into a piece of Steel, that it shall take up a piece of Iron of two Ounces weight or more; and give also to a Needle, the vertue of conforming to the Magnetical Meridian, without the help of a Load-Stone, or anything else, that hath received vertue therefrom. So far this Answerer; whom as we cannot but much commend for his diligence in searching, and frankness of communicating; so we give these particulars to the publick, that further Tryals may be made by others, for more discovery; hoping withall, that the same Inquisitive person, that hath made these returns, will not scruple to add to them the wayes, he uses for infusing that Magnetical vertue into Steel and Needles, without the help of a Load-Stone, spoken of in the end of this his Answer. Extract of a Letter, Written from Paris, containing an Account of some Effects of the Transfusion of Blood; and of two Monstrous Births, &c. I was present, when M. Gayant shew'd the Transfusion of the Blood, putting that of a Young Dog into the Veins of an Old, who, two hours after, did leap and frisk; whereas he was almost blind with age, and could hardly stir before. In the House of M. Bourdelots was shew'd a Monster in form of an Ape, having all over its shoulders, almost to his middle, a mass of flesh, that came from the hinder part of its head, and hung down in form of a little Cloak. The report is, that the Woman that brought it forth, had seen on a Stage an Ape so cloathed: The most remarkable thing was, that the said mass of flesh was divided in four parts, correspondent to the Coat, the Ape did carry. The Woman, upon inquiry, was found to have gone five months with Child; before she had met with the accident of that unhappy sight. Many questions were on this occasion agitated: viz., about the Power of Imagination; and whether
