called Mot tit Plag*. In this Common Experiment, the Caufe of the Enclo- 

 fure of the Bubble is for that the Appetite to refill Separation, or Difcon- 

 tinuance, (which in folid Bodies is ftrong) is alfo in Liquors, though fain- 

 ter and weaker 5 As we fee in this of the Bubble : we fee it alfo in little Glaf- 

 fes of Spittle that Children make of Rufhes And in Caftles of Bubbles, 

 which they make by blowing into water, having obtained a little Degree of 

 Tenacity by Mixture of Soap ; We fee it alfo in the Stilltcides of water, 

 which if there be water enough to follow,, will Draw themfelvesinto a fmafi 

 thred, becaufe they will difcontinue 5 Jm if there be no Remedy, then 

 they, caft themfelves into round Drops • which is the Figure, that faveth 

 j the Body moft from Difcontinuance .; The fame Reafon is of the Round- 

 j nefs of the Bubble, as well for the Skin of Water, as forttie Air within: 

 For the Air likewife avoideth Dif continuance - 7 And therefore cafteth it 

 felfintoa round Figure. And for the flop and Arreft of the Air a little 

 while, itfheweth that the Air of it felf hath little, or no Appetite, of 

 Afcending. 



TH E Rejection, which I continually ufe, of Experiments, (though it 

 appeareth not) is infinite $ But yet if an Experiment be probable in the 

 Work,and of great Ufe, I receive it, but deliver it as doubtfull. It was re- 

 ported by a Sober Man, that an Artificial! Spring may be made thus : Find 

 out a hanging Ground,where there is a good quick Fall of Rain-water. Lay 

 a Half-Trough of Stone, of a good length, three or four foot deep with- 

 in the fame Ground ; with one end upon the high Ground, the other upon 

 the low : Cover the Trough with Brakes a good thicknefs, and caft Sand 

 upon the Top of the Brakes.- You flaall fee, (faith he) that after fome 

 ihowres are part, the lower end or the Trough will be like a Spring of 

 water: which is no mar veil, if it hold, while the Rain-water lafteth ; But 

 he faid it would continue long time after the Rain is pad ; As if the water 

 did multiply it felf upon the Air, by the help of the Coldnefs and Con- 

 densation of the Earth,and the Contort of the firft Water. 



T. H E French, (which put off the Name of the French Difeafe, unto the 

 Name of the Difeafe of Naples)do report, that at the Sie^e o{ Naples, 

 there were certain wicked Merchants that Barrelled up Mans flefl), (of iome 

 that had been lately llainin Ba.rbta.fi) and fold it for T mnej h And that upon 

 that foul and high Nourifhment, was the Onginall of thzx*DijeaJe. Which 

 may well be For that it is certain, that the Caniballs in the Wejl-Indies, eat 

 Mans fiejh ; And the Weft- Indies were full of the Pocks when they were firft 

 difcovered : And at this day the Mortaleft pojfons, pra&ifed by the Weft In- 

 dians, have fome Mixture of the Blood, or Fat, or Flelh of Man : And di- 

 vers Witches, and Sorcereftes, as well amongft the Heathen,^ amongft the 

 Chriftians, have fed upon Mans' flefl), to aid(as it ieemeth)their Imagination, 

 with high and foul Vapours. 



IT feemeth that there be thefe wayes (in likelyhood) of Verfton of Va- 

 pours or Air, into Water and Moifture. The firft is Cold ; which doth ma- 

 nifeftly Condenfe 5 as we fee in the Contracting of the Air in the Weather- 

 Glafi? whereby it is a Degree nearer to Water. W e fee it alfo in the Genera- 

 tion of Springs 7 which the Ancients thought (very probably ) to be made by 

 the Ver [ion of Air into Water, holpen by the Reft, which the Air hath in 

 thofe Parts-, whereby it cannot dilTipate. And by the Coldnefiot Rocks h for
