TO try some suspicions I had about the Saline and Aqueous Parts, that I thought might he con∣cealed in the Fibrous or Consistent part of Humane Blood, I caused some of it to be in an open and shal∣low Glass exposed to the Air in a Frosty Night, and the next morning found it to be lightly frozen, and the Surface of the Ice prettily figur'd with resemblances of Combs, with
Teeth on both sides or edges; on which account these Figures did not ill resemble those, that I have oftentimes obtained, by slowly coa∣gulating into Salt, a solution of Sal-Armoniack made in Common Wa∣ter.
In the Second Part of the forego∣ing Memoirs, I have not said any thing of the Medicinal Vertues of Humane Blood it self, (for those of the Spirit belong to the Fourth Part) and, tho I might now, if I thought fit, say something not impertinent to that Subject, in this Appendix, both out of some Printed Books and my own observations, yet I now forbear to do it, not only for a reason that 'tis not necessary I should here declare, but because four or five Processes that I have met with a∣bout Humane Blood in Paracelsus, Burgravius, (famous for his Bioly∣chnium made of that Subject) and one or two more, about the Transplan∣tation
of Diseases by means of the Patients Blood, are such, as either I do not well understand, because of their being (probably on purpose) obscurely pen'd, or seem in them∣selves unlikely, of which sort is the Biolychnium, or Lamp of Life, in which 'tis pretended that the Blood is so prepar'd, that the state of Health of the Person whose it is, may be discover'd by the manner of the burning of the Flame it affords, (tho he be perhaps at a great di∣stance from it,) and his Death by its Extinction. Besides that, as I have elsewhere noted, some Circumstances relating to the Ashes of Humane Blood, make me doubt, whether some of these Processes were not rather the Products of Fancy than Experience. And, tho I think those Medicines less improbable, that with∣out much destroying the Texture of the Blood by Fire, aim at transplant∣ing Diseases by its intervention, yet
I thought fit to decline transcribing the forementioned Medicines, till Experience shall warrant me to do it. And I shall also at present for∣bear to set down my own Tryals, because I have not yet seen the E∣vents of them. But yet I shall in∣vite you to endeavour with me to prepare two, that, if they succeed, may afford, especially the last of them, considerable Medicines. The first Medicine that I attempted, was, by putting to Salt of Tartar Oyl of Humane Blood instead of Oyl of Turpentine: and by keeping them long, and stirring them frequently, in the open Air, to make such a Sapo∣nary Concretion, as is not unknown to many in London, by the name of Matthews's Corrector, which as he made it with Common Oyl of Tur∣pentine, tho it seem but a slight Composition, is yet esteemed and im∣ploy'd with good success, by some Doctors of Physick and other Practi∣tioners in London. To make the
other Medicine, we endeavoured to unite by long Digestion, the Salt, Spirit, and Oyl of Humane Blood, into a Mixture, which some Chymists (for their Terms are not by all of them used in the same sense) call a Clyssus. But having begun this, without having had time to finish it, we shall say no more of it, but that divers Chy∣mists may not improbably look upon this sort of Compositions, as one of the noblest sort of Pre∣parations that many a Drug is ca∣pable of.
