OF Bodies, ſome (weſee) are hard, and ſome ſoft:
The hardneſsis cauſed

Experiment
Solitary,
touching
Hard and
Soft Bodies. (chiefly) by the Jejuneneſs of the Spirits; and their imparity with the
Tangible parts: Both which, if they be in a greater degree, maketh them
not onely hard, but fragile, and leſs enduring of preſſure; as Steet, Stone, Glaß,
Dry Wood, & c. Softneſs cometh (contrariwiſe) by the greater quantity of
Spirits, (which ever helpeth to induce yielding and ceſſion;) and by the
more equal ſpreding of the Tangible parts, which thereby are more ſliding,
and following; as in Gold, Lead, Wax, & c. But note, that ſoft Bodies (as we
uſe the word) are of two kindes; the one, that eaſily giveth place to an-
other Body, but altereth not Bulk by riſing in other places; and therefore we
ſee that Wax, if you put any thing into it, doth not riſe in Bulk, but onely
giveth place: For you may not think, that in Printing of Wax, the Wax riſeth
up at all; but onely the depreſſed part giveth place, and the other remaineth
as it was. The other that altereth Bulk in the Ceſſion, as Water, or other
Liquors, if you put a Stone, or any thing into them, they give place (in-
deed) eaſily, but then they riſe all over; which is a falſe Ceſſion, for it is in
place, and not in Body.

ALl Bodies Ductile, and Tenſile, (as Metals) that will be drawn into Wires;

Experiment
Solitary,
touching
Bodies Ductile
and Tenſile. Wool, and Tow that will be drawn into Yarn or Thred; have in them
the Appetite of Not diſcontinuing, ſtrong; which maketh them follow the
force that pulleth them out; and yet ſo, as not diſcontinue or forſake their
own Body. Viſcous Bodies (likewiſe) as Pitch, VVax, Birdlime, Cheeſe toaſted,
will draw forth and roap. But the difference between Bodies fibrous, and
Bodies viſcous, is plain; For all Wooll, and Tow, and Cotton, and Silk
(eſpecially raw Silk) have, beſides their deſire of continuance, in regard of
the tenuity of their Thred, a greedineſs of Moiſture, and by Moiſture to
joyn and incorporate with other Thred, eſpecially, if there be a little Wreath-
ing, as appeareth by the twiſting of Thred, and the practice of Twirling
about of Spindles. And weſee alſo, that Gold and Silver Thred cannot be
made without Twiſting.

Other Paßi-

of Bodies. figurable; mouldable, and not mouldable; ſciſſible, and not ſciſſible;
and many other Paſſions of Matter, are Plebeian Notions, applied unto the
Inſtruments and Ufes which Men ordinarily practiſe; but they are all but the
effects of ſome of theſe cauſes following, which we will enum erate without
applying them, becauſe that would be too long. The firſt is the Ceſſion, or
not Ceſſion of Bodies, into a ſmaller ſpace, or room, keeping the out ward
Bulk, and not flying up. The ſecond is, the ſtronger or weaker Appetite, in
Bodies, to continuity, and to flie diſcontinuity. The third is, the diſpoſition
of Bodies, to contract, or not contract; and again, toextend, or not extend.
The fourth is, the ſmall quantity, or great quantity of the Pneumatical in
Bodies. The fifth is, the nature of the Pneumatical, whether it be Native
Spirit of the Body, or common Air. The ſixth is, the Nature of the Native
Spirits in the Body, whether they be Active, and Eager, or Dull, and Gentle.
The ſeventh is, the emiſſion or detenſion of the Spirits in Bodies. The eighth
is, the dilatation or contraction of the Spirits in Bodies, while they are de-
tained. The nineth is, the collocation of the Spirits in Bodies, vvhether the
collocation be equal or unequal; and again, vvhether the Spirits be coacer-
vate or diffuſed. Thetenth is, the denſity or rarity of the Tangible parts.
