Two bodys being uniformely moved in the same plaine their center of motion which describe a streight line

[105] The 28th & 30th proposition done otherwise

[106] Or thus

[107]
The {illeg} of motion is {illeg} before after {illeg}
[108]

The center of motion in finite bodys hath the same velocity before & after reflection
