the lame kind : which the Schools, in a vain apprehenfion call the »o«- 

 Tonderation of a body xvithin its oven Sphere. All the(e do vary the 

 Motion of Gravity 5 for heavy fubjiances are otherways moved in fcaleSj 

 otherwife in falling down j nay30thefwire(which may feem ftrange) in 

 Ballances hanging in the Air, otherwile in Ballances imraerfed in Wa- 

 ter j otherwife in falling down through Water, otherwife in fwim- 

 ming, or tranfportation upon Water. 



6. Let it be inquired, what the Figure of a body de(cending may, or 

 doth work, to the moderating of the Motion of Gravity^ as a broad Fi- 

 gure with tenuity ; a cubick Figure^ long round , Pyramidal 5 when 

 they turn j when they remain in the lame pofture, wherein they were 

 deliver'd. 



7. Let inquiry be made'o/i that which the Continuance and Progrejflon 

 of a Fall ox Defcent'^mZiy ,^nd doth work to this efFeft,that it may be car- 

 ried with a greater incitation and force; and with vvhatproportion,and 

 how far that Incitation will carry ? For the Ancients, upon a Qight con- 

 templation, were of opinion, that becaufe that tvas a natural Motion^ it w d:^ 

 would continually be augmented and improved. ^ ^' 



3. Let inquiry be made of that which Dijiance and Froximity of a. 

 Body defcendingfrom the earthy roay, and doth work to this end, that 

 it may fall more fpeedily, more (lowly, or elfe not at all, (if fb be that it 

 be without the Orbof Aftivity of the terrene G lobe , which was Gilbert's ceMagnJ 

 opinion J; as likewise what the immerjion of a Body defcending more in 

 the deep of the earth •■) or the placing thsx^oi nearer to the fuperficies of 

 the earthy may produce ? For thefe kinds of Pofitures vary the Motion, 

 as they experience that work in Mines. 



9. Let there be inquiry made of that which the difference of Bodies, 

 by which motion of Gravity is^diffufed, and communicated, can do 

 and doth : And whether it may equally be cotnmunicated by Bodies 

 foft, and porole '■, as by hard and (olid ; As if the Beam of the Ballance 

 be on one (ide of the Tongue Wood, on the other fide Silver, Ct hough 

 they be reduced to the fame weight J whether doth it not beget a va- 

 riation in the Scales? In like manner, whether Metal put upon Wool, 

 or upon a blown Bladder, weigh the fame, it would do, if laid in the 

 bottom of the Scale ? 



10. Let there be inquiry made what the diltance of a Body from the 

 level-Poife; that is the quick, or late perception of the incumbent, or 

 ofdepre(rion, can do or doth ; As in a Ballance where one part of the 

 Beam is longer (thoughof the fame weiglit) whether this doth fway 

 the Ballance ? Or in the crooked Pipes, where certainly the longer part 

 will draw the Water, although the (hotter part, made more capacious, 

 may contain a greater weight of Water. 



11. Let there be Enquiry made of that which the intermixtion or 

 copulation of a light Body with a weighty , may do to the railing 

 of the weight of a Body , as in the poife of living Creatures, and 

 Dead? 



12. Let inquiry be made of the fecret a(cenfions , and delcenfions of 

 the parts more light, and more weighty in one, ancf the (ame entire Bo- 

 dy. Whereby there may be made oftentimes exaft feparations 5 as in 

 the feparation of Wine and Water 5 in the Afcenlion of the Flower of 

 Milk, and the like.
