Sect. II. Cap. 1. De Mosv
r DesiexAVM vel Vessigirn Morrs est locus com
munis omnium et proprius solorum mobilis locorum, m
quibus durante motus tempore fuit; locorum inquam con
gruentium seu Ves sigroxvm MosiL Is.
Loers autem PRoseirs ett, qui et alis communis non est
aliis, inquam, qua nempe punitum habeant, quod in nullo sit
mobilis loco. Seu Locus proprius veltigiorum seu locorum mo-
biles est, qui nullum punctum continet; quod non in aliquem ex
+
locis mobilis eadat.
Ut si (Fig. 5.) rectangulum punctum A in recta 1A2 A3A
vel  motum transferatur, ea 1A per 2 A in 3A, via erit recta

1A2A3A; vel si recta AD mobilis in recta quiescente. VX mota
trantferatur, ut ex 1A1 D per 2A1D m 3A3D, vra erit recta 1A3D.
Vel si recta mobilis A∞, aut etiam rectangulum AB CD intra
duas rectas 1A1D, 1B1C, continuatas in plano transferatur,
recta quidem ea 1A L B per 2 A 2B m 3A38, rectangulum vero
ea 1A, B1 C+ D. per 2 A2B2 C2D n 343B3C5D, via recta
AB, erit rectangulum 1A1B3 A3B, et via rectanguli ABCD
erit rectangulum 1A1B3C3D; Vertigium vero aliquod rectae
erit 2A2B; et rectanguli vertigium 2 A2B2C 2 D. Ubita
men discrimen insigno observari debet, quod interdum via
mobili homogenea est, intordum secus. Sic recta LA2A3 A pun-
cto A, et rectangulum 1 A1B2A3B rectae AB homogeneum non
est; sed recta 1A3D rectae AD, et rectangulum IAIB3C3D
rectangulo ABCD homogoneam est.
Nimirum generaliter (Fiig. 6.) omnis puncti F, via

cies, si puncta ejus durante motu sibi non suec edant continue;
