Chap. 4. Of the Jaundice.
THe Jaundice is a yellow color of the whol Body, coming of Choller, spread over all the Skin.
It is therefore a Symptome of the Quality changed. And now presently, that vulgar difficulty which is controverted by almost all Writers, offers it self; namely, That the yellow color in the Cornea, doth immediately hurt the Sight, making all objects appear yellow. To which (that I may answer in a word, without circumstances) I say, That it is a disease in the encrease of Number; for since the Cornea ought to be void of all color, that it may let the Species of Objects pass through pure and unchanged, if it have any pre••ernatural color, it hath a Disease in the encrease of Number, that is, more than what is necessary to the Natural Constitution thereof.
Authors do make two sorts of Jaundice; Yellow, and Black. The Black proceeds from the Spleen and is very rare: therefore here treating only of the Diseases of the Liver, we will speak only of the Yellow Jaundice.
The spreading of Choller upon the Skin, comes from many Causes; which may be reduced to three Heads: namely, An Evil Disposition of the Liver; An Obstruction of the Bag that contains the Gall; And the malignity of the Chollerick Humor.
The Evil Disposition of the Liver is divers; as Dstemper, Inflamation, Obstruction, Schirrus, and whatsoever may so weaken the part, that Excrementitious Choller cannot be separated from the Blood, but is with it distributed through the whol Body.
The Obstruction of the Bag or Cystis, which contains the Gall, hinders the passage of it into the Guts, whereby it remains in the Liver, and goes from thence with the Blood into the whol Body. This Obstruction is either from gross Flegm, or Choller abounding; somtimes from little stones which are often bred in the Bag of Gall; which may also be made narrow in the Passage, by the com∣pression of some part nigh unto it, which is inflamed or schirrous.
The Evil of the Chollerick Humor consists, either in the great quantity thereof, which cannot be regulated by Nature, nor be separated from the Mass of Blood, or which so filleth the Bag of the Gall, that it cannot contract it self to expel it; or it consists in an evil quality, which by corrupting of the Humors, doth hinder their due Evacuation, or stirs up Nature suddenly to cast it forth, as you may observe in a Critical or Symptomatical Jaundice. This Corruption happens in continual Chollerick Feavers; as also after Poyson is taken, or from the biting of some venemous Creature, by which the whol Blood is turned into Choller.
The Signs of the Yellow Jaundice are manifest; namely, a yellow color through the whol Body, especially in the white of the Eyes. Also an itching, and laziness, bitterness of the Tongue, somtimes Chollerick Vomitings, and Hiccoughs.
The Signs of the Causes are to be taken from their proper Fountains; for if the distemper of the Liver be hot, this Disease comes from Inflamation, Obstruction, Schirrus, or the like: the knowledg of which is to be taken from their proper Chapters.
These things properly shew the Obstruction of the Bag of the Gall, white Excrements, and a Bel∣ly bound through the want of Choller, which useth to make the Excrements yellow, or red, and to stir up the Expulsive Faculty of the Guts like a Clyster. The Urine is very yellow, inclining to red and if you put a Linnen clout therein, it will dye it yellow.
If it come from the malignity of the Chollerick Humor, the Excrements of the Belly are high colo∣red, and also the Urine, especially if it follow a putrid Feaver, when the Jaundice is a Symptome, and then after the coming of the Jaundice the Feaver remains: but if it be critical, the Feaver ceaseth, and the Excrements with the Urine are wel colored. The External Causes, as Poyson, and vene∣mous bitings may be declared by the Patient, and those about him.
The Prognostick of the Jaundice is various, according to the variety of Causes.
That is more Curable which comes from the Obstruction of the Bag containing the Gall, because its passages are neerer the Guts, and the Matter cleaving thereto, is easily sent into them, provided that the Obstruction come not from a stone, which because it cannot be dissolved, renders the Disease incurable.
The Jaundice coming from an Inflamation or Schirrus of the Liver, is most dangerous; for one commonly ends in an Imposthume, the other in a Dropsie.
They who in a Feaver, have the Jaundice before the seventh day, are desperate, Hipp. Aph. 62. Sect. 4. against which Aphorism, there is another of, Hippocrates opposed, which is in 4. de victus ratione in acutis, in these words: In a Chollerick Feaver, if the Jaundice come before the seventh day, with chillness, the Disease is cured; but if it come without chillness, it is deadly. There is
