Lemma
7. Cohaesionem massularum corporis solidi a nisu aequali in directiones contraries sese movendi dependere demonstravit clarissimus Wolfius (Cosmol., § 291, et Phys. dog., § 45).
Theorema I
8. Corpus solidum dum in fluidum abit, massularum nisus aequalis sese movendi in directiones contraries impediri debet.
Demonstratio
Massularum corporis solidi impediri debet mutua cohaesio, cum id in fluidum fuerit transmutandum (§ 6). Cohaesio haec ab aequali massularum nisu in directiones contrarias sese movendi proficiscitur (§ 7). Nisus itaque hie prout causa cohaesionis corporis solidi massularum impediri debet. Q. E. D.
Corollarium I
9. Quoniam sine ratione sufficiente nihil fieri potest (Ont., § 70), massularum nisus aequalis in directiones contrarias sese movendi a causa quadam impediatur necesse est, dum corpus solidum in fluidum transmutatur.
Sc ho li on
10. Causam hanc esse motum fluidi praeexistentis patebit inferius.
Corollarium II
11. Corpus solidum dum in fluidum transmutatur, vires nisus aequalis, quern massulae corporis solidi exerunt ad sese movendas in directiones contrarias, viribus causae massularum cohaesionem impedientis resistere nequeunt.
