Observation 4.

These were instituted not in the Serum, but in the clotted blood it self. To wit Mr. N. N. after he had spit blood for some years, fell into a spitting of Matter, with an inordinate or irregular Feaver, after exhibiting of Medicines, and chiefly of Adstringents, the thirtieth day of May he fell into a large Haemoptisis, or spitting of blood, he having been afflicted before it with a weightiness, and weariness of his Joynts: upon the first of August this Symp∣tom was urgent again, and he cast up much florid blood▪ which was easily coagulated. The 2d day of August after Midnight, his spitting of blood was very urgent, only he perceived his blood which he threw up to be hotter whilst it was in his mouth: it was neither putrid matter, nor Salt as heretofore. I commanded to take about four ounces of Blood, by opening a Vein in the Right Arm. The Blood which was let out was taken in two Silver Dishes, and appeared black even whilst it was flowing forth: it had little Serum, scarce two drams, and that of a Yellow Colour. The clotted blood had a florid red circle about it, the

middle part was like the skin of a Jelly. To this blood, being well dryed with spongy Brown Paper, these following things were applyed.

1. One drop of Spirit of Nitre, did presently and sooner than in the twinkling of an Eye, impress a white spot upon it, and that not superficially, but sufficiently deep, and very white.

2. The Sweet Spirit of Nitre, made no change at all.

3. Spirit of Salt, did more slowly make a spot, and that less white, and less deep. The red Circle of the blood it self, and the circumference of the drop, were both black.

4. Sweet Spirit of Salt, at the first did nothing, but after it had stood sometime upon the Liquor it did a little dissolve the outward skin of the Blood, and made a hole in it, and rendred the blood under it, (in which it was contained) of a livid flesh Colour, spotted like Marble.

5. Spirit of Vitriol did slowly make a spot a little whitish.

6. Aqua-fortis did swiftly and imme∣diately (with some Fume) make a spot altogether agreeable with that of Spirit of Nitre.

7. Spirit of Sulphur, made a Spot like that of Spirit of Vitriol.

8. The Clyssus produced a white spot.

9. Spirit of Verdigrece as to its effect a∣greed with the Sweet Spirit of Salt.

10. Arcanum Nitri stood upon the Blood in its own circumference, after∣wards it made a yellowish spot, and ren∣dred the skin of the Blood thinner, so that it might easily be divided by a twig.

11. Spirit of Sal Armoniack made no change, or spot.

12. The Liquor of Fixed Nitre ren∣dred the Blood much Redder and transpa∣rent.
