_Cancers_ and _Fistula's_ are somewhat alike, in that they are both produced from Salt, or sharp corroding Motions: but in this they differ, that Cancers keep their Center, and spread in streams; whereas _Fistula's_ will run from place to place: for if it be stopt in one place, it is apt to remove and break out in another. Yet _Cancers_ are somewhat like _Gangren's_, in infecting adjoining Parts; so that unless a _Cancer_ be in such a place as can be divided from the Sound Parts, it destroys the Human Life, by eating (as I may say) the Sound Parts of the Body, as all Corroding, and Sharp or Salt Diseases do. CHAP. XI. Of the GOVT. As for the Disease named the _Gout_, I never heard but of Two sorts; the _Fixt_, and the _Running Gout_: but, mistake me not, I mean _Fixt_ for _Place_, not _Time_. The _Fixt_ proceeds from Hot, Sharp, or Salt Motions: The _Running Gout_ from Cold, Sharp Motions; but, both sorts are Intermitting Diseases, and very painful; and I have heard those that have had the _Fixt Gout_, say, That the pain of the Fixt Gout, is somewhat like the Tooth-ach: but, all Gouts are occasioned by Irregular Pressures and Re-actions. As for that sort that is named the Windy Gout, it is rather a Sciatica, than a Gout. CHAP. XII. Of the STONE. Of the Disease of the _Stone_ in Human Creatures, there are many sorts: for, though the _Stone_ of the _Bladder_, of the _Kidneys_, and in the _Gaul_, be all of one kind of Disease called the _Stone_, yet they are of different sorts: but, whether the Disease of the _Stone_ be produced of Hot or Cold Motions, I cannot judg: but 'tis probable, some are produced of Hot Motions, others of Cold; and perchance, others of such sorts of Motions as are neither perfectly Hot, nor Cold: for, the _Stone_ is produced, as all other Creatures, by such or such sorts of Figurative Motions. Here is to be noted, That some of the Humours of the Body may alter their Motion, and turn from being Flegm, Choler, or the like, to be _Stone_; and so from being a Rare, Moist, or Loose Body, to be a Dry, Densed, Hard, or Fixt Body. But certainly, the _Stone_ of the _Bladder_, _Kidneys_ and _Gaul_, are of several sorts, as being produced by several sorts of Figurative Motions; as also, according to the Properties and Forms of those several Parts of the Body they are produced in: for, as several sorts of Soyls, or Parts of the Earth, produce several sorts of Minerals; so several Parts of the Body, several sorts of the Disease of the _Stone_: And, as there are several sorts of Stones in the several Parts of the Earth; so, no doubt, there may not only be several sorts of Stone in several Parts, but several sorts in one and the same Part; at least, in the like Parts of several Men.
