at all. But neverthelefs , if you know it not, or enquire it not attentively 

 and diligently, you (hall never be able to difcern, and much , lefs to pro- 

 duce, a Number of Mechanic all Motions. Again, as to the Motions Corpo- 

 rally within the Enclofures of Bodies, whereby the Effects (which were 

 mentioned before)pafs between the Spirits, and the T angibk, Parts, (which 

 are Arefaliion, Colliquation, C one oU ion, Maturation, &c. )they are not at all 

 handled. But they are put off by the Names of Fertues, and Natures, and 

 jStiom,m& PafJions,md fuch other Logical! Words. 



IT is certain, that of all Powers in Nature, Heat is the chief-, both in the 

 Frame of Nature, and in the works of Art. Certain it is likewife, that 

 the Effects of He at, are moft advanced, when it worketh upon a Body with- 

 out lots or dillipation of the Matter for that ever betray eth the Account,; 

 Arid therefore it is true, that the power of Heat is beft perceived in Di filia- 

 tions, which are performed in clofe Veil els, and Receptacles. But yet there 

 is a higher Degree ^ For howfoever Di filiations do keep the Body in 

 Cells,and Cloyiters, without Going abroad, yet they give fpace unto Bo- 

 dies to turn into Vapour - To return into Liquour And to Separate one 

 part from another. So as Nature doth Expatiate, although it hath not full 

 Liberty: Whereby the true and Ultime Operations of Heat are not attai- 

 ned. But if Bodies may be altered by Heat, and yet no fuch Reciprocation of 

 Rarefaction: and of Conden fat ion, and of Separation,2dmitttd -, then it is like 

 that this Proteus of Matter, being held by the Sleeves, will turn and change 

 into many Met amorphous . Take therefore a Square Fejfell of Iron, in form of 

 a Cube, and let it have good thick and ftrong Sides. Put it into a Cube of 

 Wood, that may fill it as clofe as may be A nd let it have a Cover of Iron as 

 flrong(at leaft,as the Sides And let it be well Luted, after the manner of 

 dp Cbjmijls, Then place the Fefjell within burning Coals kept quick kind- 

 led,tbr fomefew houres fpace. Then take the Fefjell from the Fire, and take 

 off the Cover, and fee what is become of the Wood. 1 conceive that fince all 

 Inflammation, and Evaporation are utterly prohibited, and the Body mil tur- 

 ned upon it Self, that one of thefe. two Effects will follow-, Either that 

 the Bodj of the Wood will be turned into a kind of Amalagma, (as the cby- 

 mifls call it - ) Or that the Finer Part'will be turned into Air, and the GroT- 

 fer ftick as it were baked, and incruftate upon the Sides of the Fefjell -, being 

 become of a Denfcr Matter, than the Wood it felf, Crude. And for another 

 Triall,take alfo Water, and put it in the like VclTell, ft opped as before •, But 

 ufe a gentler Heat and remove the VeiTell fometimes from the Fire-, And 

 again, after fome fmall time, when it. is Cold renew the Heating of it : And 

 repeat this Alteration fome few times : And it you can once bring to pafs, 

 that the Water, which is one of the Simpleft of Bodies, be changed in Co- 

 lour, Odour, orTaft, after the manner of Compound Bodies, you may be 

 fure that there is a great Work wrought in Nature, and a Notable En- 

 trance made into ftrange Changes of Bodies, and productions : And alfo a 

 Way made to do that by Fire, in fmall time, which the Sunne and Age 

 do in long time. But of the Admirable Effects of this Diflillaticn in C lofe, 

 (for fo we call it)which is like the Wombs and Matrices of living creatures, 

 where nothing Expireth, nor Separated! -, We will fpeak fully, in the due 

 place 5 Not that we Aim at the making of Paracelfus pigmeys h Or any fuch 

 Proaigious Follies-, But that we know the Effects of Heat will be fuch,as 

 will fcarce fall under the Conceit of iMan -, If the force of it be altogether 

 kept in.
