Chap. 5. Of the differences of Diseases that come from the in∣ternal fault of the Humors.
THere are two chief differences of Diseases from internal humors. The first are ma∣lignant, but kill not, onely cause greater Symp∣toms then the first qualities can produce, with these a man may live long.
The second are such as presently kill, and are well called Venemous.
Of the first sort are the humors that cause an Epilepsie, fear of water, dancing, madness, Scur∣vey, Colick, and malignant Dysenteries, Ele∣phantiasis, Gangrene, and simply malignant Fe∣ve••s. Of the second sort, are the humors that be∣get pestilent feavers, and the plague.
As for the first sort, the Epilepsie and the other diseases are not the evident causes, or from ob∣struction of the ventricles of the brain, nor is fe•••• of water, from the biting of a mad Dog. But this Epilepsie is from a humour or vapor that hurts the membranes of the brain, and the nerves espe∣cially. And fear of water may come from inter∣nal humors without the biting of any mad crea∣ture. Mercellus Donatus hath five Examples of this, and the diseases mentioned are not from manifest qualities, but from malignant, occult and venemous causes.
As for the second kind, the humors are so cor∣rupted, that they do not only turn malignant, but breed deadly diseases, that kil like poyson, as pe∣stilent Feavers and the Plague, Buboes and Car∣bun••les, of which before.
