CHAP. XXXI. Of the Feaver which happeneth in Scirrhous Tumors.
SVch a Feaver is a Quartaine, or certainly comming neare unto the nature of a Quartaine, by reason of the nature of the Melancholike * 1.1 humor of which it is bred. For this shut up in a certaine seat in which it makes the tumor, by communication of putride vapours heats the heart above measure, and enflames the humors conteined therein, whence arises a Feaver. Now therefore a quartaine is a Feaver comming every fourth day, and having two dayes intermission.
The primitive causes thereof are, these things which encrease Melancholicke humors in the body, such as the long eating of pulse, ofcourse and burnt bread, of salte flesh and fish, of grosse meates as Beese, Goate, Venison, olde Hares, olde Cheese, Cabbage, thicke and muddy wines and other such things of the same kinde.
The antecedent causes are a heaped up plenty of Melancholicke humors aboun∣ding over all the body. But the conjunct causes are Melancholike humors putrify∣ing without the greater vessels, in the small veines and habite of the body.
We may gather the signes of a Quartaine feaver from things which they call natu∣rall, not naturall, and against nature; from things naturall, for a cold and dry * 1.2 temper, oldeage, cold and fat men, having their veines small, and lying hidde, their spleene swolne and weak, are usually troubled with quartaine Feavers.
Of things not naturall; this Feaver, or Ague is frequent in Autumne, not onely because, for that it is cold and dry, it is fit to heape up Melancholike humors; but * 1.3 cheifly by reason that the humors by the heate of the preceding Summer are easily converted into adust Melancholy, whence far worser and more dangerous quar∣taines arise, than of the simple Melancholike humor; to conclude, through any cold or dry season in a region cold and dry, men that have the like Temper easily fall into quartaines; if to these a painefull kinde of life full of danger and sorrow doth accrew.
Of things contrary to nature; because the fitts take one with painefull shaking, inferring as it were the sence of breaking or shaking the bones; further it taketh one every fourth day with an it ching over the whole body, and oft times with a thinne skurfe and pustles especially on the legges; the pulse at the beginning is litle, slow, and deepe, and the urine also is then white and waterish, inclining to somewhat a darke colour.
In the declination when the matter is concocted the urine becomes blacke, not occasioned by any maligne Symptome or preternaturall excesse of heat, (for so it should be deadly) but by excretion of the conjunct matter. The fit of the Quar∣taine continues 24 houres, but the intermission is 48 houres. It often takes its
