it; and on the other side that some very subtil Spirits actually cold, being put into cold Water, will quickly produce in it a sensible warmth, I thought it would not be amiss to try, what Spirit of Humane Blood would do, when employed after the same man∣ner. Having therefore placed a seal∣ed Thermoscope in an open mouth∣ed glass, furnished with as much distilled water as would cover the Ball of the Instrument, we left it there for a while to bring the internal Li∣quor and the external to the same degree of Coldness. Then we pour∣ed upon the immersed Ball two or three spoonfuls of Spirit of Humane Blood (which was all we could spare for this Tryal) but perceived very little alteration to ensue in the Ther∣moscope, only that it seemed, the Spirit of Wine in the stem did a little, and but a very little, subside which effect (tho it had been much more manifest) I should not have been sur∣priz'd

at, partly because I found Spi∣rit of Urine to have a like, or some∣what more considerable effect, and partly because I remembred, what I elsewhere relate about the Operati∣on of the pure Salt of Humane Blood upon Distill'd Water; which Liquor I therefore make use of in these and many other Experiments, because in our common Pump-Water or Well-Water, and in most other common Waters, I have observed a kind of common Salt, which tho in very small quantity, makes it apt to coa∣gulate with, or precipitate, some kind of Saline Corpuscles, whether more simple, or more compounded. But before I quite dismiss the lately reci∣ted Experiment, I must acknowledge, that I dare not acquiesce in it. Since probably the effect of the Spirit of Blood would have been more consi∣derable, if I had been furnish'd with a sufficient quantity of it, to pour in∣to the Water.
