46XXXIV ſequor earum diſcrimina: oſtendo nimirum, quo
pacto varias induere poſlint figuras quaſcunque,
quarum tenaciſſimæ ſint; poſſint autem data quavis
figura diſcrepare plurimum in numero, & diſtri-
butione punctorum, unde & oriantur admodum
inter ſe diverſæ vires unius particulæ in aliam, ac
itidem diverſæ in diverſis partibus ejuſdem parti-
culæ reſpectu diverſarum partium, vel etiam re-
ſpectu ejuſdem partis particulæ alterius, cum a ſolo
numero, & diſtributione punctorum pendeat illud,
ut data particula datam aliam in datis earum di-
ſtantiis, & ſuperficierum locis, vel attrahat, vel
repellat, vel reſpectu ipſius ſit prorſus iners: tum
illud addo, particulas eo difficilius diſſolubiles eſ-
ſe, quo minores ſint; debere autem in gravitate
eſſe penitus uniformes, quæcunque punctorum díſ-
poſitio habeatur, & in aliis proprietatibus pleriſ-
que debere eſſe admodum (uti obſervamus) diver-
ſas, quæ diverſitas multo major in majoribus maſſis
eſſe debeat.

A num. 426 ad 446 de ſolidis, & fluidis, quod
11426 diſcrimen itidem pertinet ad varia cohæſionum ge-
nera; & diſcrimen inter ſolida, & fluida diligenter
expono, horum naturam potiſſimum repetens ex
motu faciliori particularum in gyrum circa alias, at-
que id ipſum ex viribus circumquaque æqualibus;
illorum vero ex inæqualitate virium, & viribus
quibuſdam in latus, quibus certam poſitionem ad
ſe invicem ſervare debeant. Varia autem diſtin-
guo fluidorum genera, & diſcrimen profero inter
virgas rigidas, flexiles, elaſticas, fragiles, ut &
de viſcoſitate, & humiditate ago, ac de organi-
cis, & ad certas figuras determinatis corporibus,
quorum efformatio nullam habet difficultatem, ubi
una particula unam aliam poſſit in certis tantum-
modo ſuperficiei partibus attrahere, & proinde co-
gere ad certam quandam poſitionem
