And as Fevers, and Swellings attending and prolonging the Cure of Fractures, are accounted for the same way; why may it not by the same parity of Reason be admitted, that the Bite or Wound of a Bugg should swell and inflame such only whose Blood is out of order; and tho’ they do bite, cause no Inflammations on any in right order of Blood? The best Reason which can be given in support of this Error, is, That where two Persons lie in one Bed, one shall be apparently bit, the other not. Buggs indeed, where there are two Sorts, may feed most on that Blood which best pleases their Palate; but that they do taste the other also, to me is apparent: And whenever that Bedfellow who is most liked by Buggs shall lie from home, the other will so sensibly feel the effects to be as above, that they will no longer think themselves bite-free. Of this I am sensible, that I daily am bit when practising and at work in my Business, destroying them; and as they never swell me but when out of order, from thence I infer, that not only myself, but all such who are among Buggs, and do not swell with their Bites, are certainly in good Habit of Body. But to return to my Subject. Having shewn that they not only live in Winter, but asserted that to be the best Season for their total Destruction, I must further observe, that few People caring to trouble themselves about Buggs but when they themselves are troubled by them, having confin’d the Attempts for their Destruction chiefly to the Breeding-Season, has been the sole Reason why the best Efforts for their Destruction have fail’d. I do admit innumerable Quantities have been destroy’d, and much good has and may be done in Summer: but should every old Bugg then be destroy’d, you are yet not safe; for the Nits behind Wainscot and in Walls, which cannot be come at, will by heat come to life, and your work is partly to be done over again. Whereas, on the contrary, if cleared out of Spawning-time, there is a certainty, as there is then no Nits, that their Offspring cannot plague you thereafter. ’Tis for this Reason I warrant what I do in Winter; which I cannot pretend to do in Summer. In Summer indeed I do destroy all Buggs and Nits too in Beds and their Furniture, but Buggs only behind Wainscot and in Walls: for tho’ my Liquor has an attractive as well as the destructive Quality, and thereby does bring out and destroy every live Bugg; yet their Nits being inanimate, cannot come to the Liquor, nor the Liquor at them. Such Nits therefore will come to life by heat, and quit the Walls and Wainscot for better Quarters and Food in the Bed, and so become troublesome to you. * * * * * Having thus given, I hope, a satisfactory Account of this nauseous, venomous Vermin, I shall proceed to shew how they are daily brought to _England_, and into Houses commonly; then give some necessary Cautions how to avoid them, and Directions how to destroy them.
