4. There are many also that attribute the Generation of this Creature to Hogs Hair, which being mixed with Lime, and Houses Plaistered with it, does occasion (say they) the Generation of Bugs. Now it is most certain, that there is no possibility in Nature for this Production: For no kind of Hair ever breeds any Living Creature, except it be put into Water or Mud when the Sun is powerful, and then this Creature, thus generated, retains its first _Species_, _viz._ a Hair, with a live Head, which was its Element whence it proceeded: but if you take it out of the Water, it presently dies: So also it doth when the Sun declines in Heat, as most sorts of Vermin that are bred through Heat and Moisture do. But Hair being mixed with Lime, all Matter of Generation is thereby totally destroyed: For Lime does chiefly contain a harsh, fiery, keen, sharp, corroding Quality; it is so sharp, that it does destroy all Life, and is as contrary to it, as Light is to Darkness; the predominant Quality in it is the Salts Nature, from which no Living Creature can be produced. Besides, if there were never so much Matter in Hair for the Generation of such Vermin, Lime would destroy it; for in Lime there is only a Sal-nitral fiery Vertue. 5. If the Reasons before-mentioned be not sufficient to convince the Ignorant of their erroneous Opinions in this particular, then I hope the following one will, which is more familiar to every one. It hath never been known, that this troublesom Vermin was ever seen in Warehouses, Kitchens, Parlours, Dining-rooms, or any Places where Beds have never been, except they have by accident been brought into such Rooms or Warehouses, by Furniture of Chambers that have been troubled with them, though all such Places have the same Furniture as Chambers, except Beds. 6. From the same Substance or Matter whence Bugs are bred, is also occasioned the Generation of many nasty Diseases in the Blood; so that the destruction of the Matter that breeds them, is of greater Consequence than most People are sensible of: And if these following Rules be observed, I dare affirm, That the Generation of Bugs will cease, and also many other Inconveniencies and Distempers, that are got by this sort of Uncleanness, will be avoided.
