Observation 1.

Mr. N. N. by birth of Clive, of thirty

years of age, he was Scorbutick, had red Spots, and Pustils in his Face, a heaviness and weariness in his Ioints, and a numness, a flushing in his Face after drinking strong Wine, or strong Beer, or the Swalbasher Spaw Water, and was obnoxious to bleed∣ing Gums, and the like; after having ta∣ke Pills upon the 28 day of Iuly, 1671. He was let Blood in the left Arm, and had about seven Ounces taken from him, in three Porringers. The Blood was very hot in its flowing forth: the day before he had drank Wine largely, after which he was cold, his Blood had much Serum, and the grumous and curdled parts were very red, and would easily be divided by a Twig; in the bottom it was of a bright Bay colour, the Serum poured off, was of the colour of Lee, like Vrine of a Citron colour tending to red: It was divided into twelve Dishes, and the Liquors being mixed with it, things appeared thus.

First, With Spirit of Nitre dropt on it, it presently coagulated into a substance like cheese, from the top to the bottom of the Liquor, in that space the Spirit was dropt into: This Curd was white on the top, but towards the bottom yellow like Sul∣phur, the rest of the Serum swimming about

it was clear, but dropping in Spirit of Nitre it also became of a Cheesy substance; some of the Liquor which remained, poured out clear like water, upon inclining of the Vessel.

Secondly, The sweet Spirit of Nitre be∣ing drop'd on, made no alteration; but after a short time, the upper half of the Liquor grew altogether clear, but the lower half was a little troubled, yet so, that there could scarce any difference be dis∣cerned but by curious Chymical eyes.

Thirdly, Spirit of Salt did presently pervade the Liquor, not only in that place where it was drop'd in, but through the whole circumference of the Liquor, and about the bottom precipitated a white co∣agulum, but not stiff.

Fourthly, The sweet Spirit of Salt did trouble the Liquor a little, but in a short time there was a separation made like the cream of Milk, which swam at the top.

Fifthly, Spirit of Vitriol, did precipitate a White Curd equally from all parts to the bottom, almost Analogous to the curd made with the sweet Spirit of Salt, but thinner.

Sixthly, Aqua-fortis did altogether a∣gree with the Spirit of Nitre, both in the whiteness of the Curd, its yellowish bottom,

and the clearness of the Liquor which was left uncoagulated.

Seventhly, Spirit of Sulphur, converted the whole Liquor into a white coagulum, or Curd, except a few drops which were left.

Eightly, The Clyssus (or the Sulphureous acid Spirit of Antimony) being dropped in, precipitated to the bottom of the Li∣quor a Curd, which was on one side White, and Cheesy, and on the other side transpa∣rent, and like a Ielly.

Ninthly, Arcanum Nitri (that is the So∣lution of the Salt of the caput Mortuum of Aqua-fortis, or its red Earth left in the bot∣tom of the Retort) dropped in, at the be∣ginning it did presently fall to the bot∣tom of the Liquor in which it was put: nor would it be mixed with it, so that it might be very well discerned from it, but after an hour or two, the Liquor was of an bigher Colour, and there settled in the bot∣tom of the Vessel a troubled Sediment, which upon slightly shaking of the Glass united again with the Liquor.

Tenthly, The Salt Spirit of Sal Armo∣niack did introduce no alteration at all in the Liquor, neither in its Colour, nor in its consistence.

Eleventhly, The fixed Liquor of Nitre, did thicken and trouble this Liquor, and precipitated to the bottom a certain Sal∣tish Curd, the Liquor which swam at the top was very clear.
