causing this pain. Also Pustles inflamed from scrat∣ching come from pain which follows, though at the first it seems pleasant. Also it often comes to pass, that not on∣ly the part pained swelleth, but the adjacent parts if they be apt to receive Defluxions, as the Kernels in the Groins, Arm-pits, and behind the Ears, when there is any pain from the Causes or Diseases montioned. And a trouble∣som Scab in these parts, hath commonly a Bubo accompa∣nying it. And the pestilential Bubo comes as I shewed, not so much from the Plague, as from the burning and pain of the Carbuncle near it.
Also these Pains are longer and worse, when the blood easily and constantly flows thither, and the part is conti∣nually pained. As when there are swell'd Leggs in a Dropsie, if the skin be open, there is a constant Flux of water which by its corruption through long abiding in the Body, is pernicious and corroding; And also of blood being thin, which causeth the perverse and ulcerated Ery∣sipelas which so easily gangraenes.
When outward heat doth long or much afflict the skin,
it doth not only make it thin, but inflames it, and the blood near to it, and makes it flow, causing Erysipe∣las or Inflammations, especially in tender and sanguine Constitutions, and such as are subject thereto. As when they sit too long by the sire and burn their Shins, or inflame them∣selves by long suning. As I did by riding in a hot day when I was young, my Boots were so hot that they made my Leggs burn, and look red two dayes after. This I have had often, and it came at first with red Spots, which tur∣ned first blew, after yellow, and then vanished. They may also come from hot water, and after bathing, as the pustles called in high Dutch Eyssen, when in the time of the Bodies being hot, they use cold water, which causeth a sudden re∣percussion, so that the Blood flies back suddenly and returns with pain. Also other moderate heat may cause Itch, and that scratching, and so pustles. Also Inflammation of particular parts may cause them, as of the Roots of the Nails. Then they are called Paronychiae, as when Maids by washing their Hands in foul hot water often, do cause their Nails to be crooked, and the Roots inflamed.
Also other excrementitious and pre∣ternatural Humors thrown to the skin,
and there fixed cause pustles, as blood dispersed into divers parts, and these may grow greater, and turn into Ulcers, small or great, or corroding, or venemous, as the quality is.
Humors that have an occult quality that is malignant, produce a little swelling or pustle, according to their Ve∣nom.
A venemous Humor so infecteth the parts,
that somtimes at first there is a little Tumor which only causeth a little pricking, but is most dangerous, in that it will not away; because while it is nourished with the other parts of the Body, it makes the Nourishment like unto it self, and converts it into Venom, and so increaseth by degrees, and grows broader and deeper, and at length becomes a Cancer, consisting of a fleshy substance full of Veins, with no In∣flammation or Tumor, but Blood in the Veins, which itcheth and pricketh, which shews its malignity by its constant increase, till there is an Ulcer, and then it goes no further but with its Claws that come from the Body it creeps on, we know the whole to be malignant, because if it be not taken out by the Root, it cannot be cured, and the least portion remaining will grow again.
It is a hard thing to know whence this Matter and Poy∣son first comes, or to describe the Nature of it but by the effect. But that it came by Touch and Infection, because the Elephantiasis whose Cause is the same with that of the Cancer, and therefore is called the gene∣ral Cancer comes from Contagion, but the Cancer is worst, because the Humors are all in one place. And as there are few that have Cancers, so are there sew Lepers, for the Venom lyeth lurking in the Veins, and comes to the part infected with the Blood, and when the Cancer in∣creaseth, it weakneth the Body by degrees. And this may be an argument, that there is a Contagion in the breeding of a Cancer, because I knew two Women that attended u∣pon two other that had Cancers a long time in their Breasts, that consumed them which were themselves infect∣ed with Cancers, and perished therby after long torment, the one being near of kin to her Mistriss. But we cannot yeeld that it comes from Melancholy, for these reasons: For if it comes from Natural Melancholy, which they say is the Dreggs of the Blood, there would some signs thereof appear, and such blood would be there gathered out of the Vessels, if there should be a Tumor or Inflam∣mation, which are not. And if it come from preternatu∣ral Melancholy, there would be at the first coming a bur∣ning, corroding, and blackness, as in the Carbuncle which is not so, but a Cancer is like Flesh, and not very painful.
A pestilent Pustle comes from poy∣son of another Nature,
which we call a Carbuncle, with venemous force, and with little burning, but with itching and pricking, only as I said of a Can∣cer; somtimes with Inflammation round about, and a Bubo hard by, which corrupteth the part, and mollifieth till it falls out back from the sound.
This poyson comes from that pestilent Poyson that got into the Body, and caused a pestilent Feaver by its destru∣ctive quality and heat, as I shewed when it gets outward. And we shewed in pestilential Feavers, that I and others have been infected with pestilent Pustles taken outward∣ly.
Some Humors cause Scabs, Itch, and Carbuncles,
by a manifest qua∣lity that corrodes and burns, and Pu∣stles with Ulcers; these are either preternatural, yellow, and green, and black Choler, or salt, sharp, or ma∣lignant, and go the Superficies of the Body, with the blood and serum, and cause pustles and in∣flammations, if they come with blood or pain; or they come without this Flux from the Veins by sweat, accord∣ing to the diversity of these Humors, are different Scabs, Itch, and Carbuncles, as we shall shew.
If in the common moist Scab, there be Itch and corro∣ding without great burning, the Humor is not so hot but salt, and gentle Choler, or tempered with water, is fallen from the Veins upon the skin, when there is no redness or Inflammation: But if there be, they shew it come with blood moved by scratching or pain, as also may appear by the suppuration that follows. When those things are as in the worst Scab, with yellow or green Matter, it comes from thicker and worse Choler, as the colour shews, as in Terminthis and Epinyctis, the pustles are very burning, with Inflammation and Suppuration following. Especially in a Carbuncle are the pustles very burning, which shews that they come from very hot Choler, and the Feaver shews they come from Blood, and their sudden appearing shews that they come from Defluxion. And we cannot gather that black Choler was the Cause, by their black∣ness, because others are black when they are dry. But from the great Heat that burns and corrupts the skin, and makes it black, and will not let them suppurate, we may conclude that either black Choler or green was the cause.
This ••••ews that the pustles in Herpes come not from a Flux of Humors, but from a Collection made there, be∣cause they come by degrees without Inflamation. And if the Herpes be called Miliaris, there is great Heat and Pu∣stles dry, and therefore the Choler was yellow, milder, and thinner, and went to the Superficies of the skin. If it be Herpes Esihiomenus the Choler is worse and green, and
