Physiologia Epicuro-Gassendo-Charltoniana, or, A fabrick of science natural, upon the hypothesis of atoms founded by Epicurus repaired [by] Petrus Gassendus ; augmented [by] Walter Charleton ...

SECT. II.

ARTIC.

1 ARistotles Definitions of Natural and Vi∣olent motion; incompetent▪ and more adaequate ones substituted in the room of them.

444

2 The same deduced from the First Epicurean Principle of motion, praemised: and three con∣siderable Conclusions extracted from thence.

445

3 A short survey of Aristotles whole theory con∣cerning the Natural motion of Inanimates: and the Errors thereof.

446

4 Uniformity, or Aequability, the proper Chara∣cter of a Natural motion: and the want of u∣niformity, of a Violent.

447

5 The Downward motion of Inanimates, derived from an External Principle; contrary to Ari∣stotle.

449

6 That that External Principle, is the Magne∣tique Attraction of the Earth

450

7 That the Vpward motion of Light things, is not Accelerated in every degree of their As∣cent as Aristotle praecariously affirmed: but, the Downward motion of Heavy things is Ac∣celerated in every degree of their Descent▪

ibid

8 The Cause of that Encrease of Velocity in Bodies descending; not the Augmentation of their Specifical Perfection as they approach neerer and neerer to their proper place: as Simplicius makes Aristotle to have thought.

452

9 Nor the Diminution of the quantity of Aer underneath them: as some Others conjectured.

ibid.

10 Nor, the Gradual Diminution of the Force imprest upon them, in their projection upward: as Hipparchus alleadged.

453

11 But, the Magnetique Attraction of the Earth.

ibid.

12 That the Proportion, or Ration of Celerity to Celerity, encreasing in the descent of Heavy things; is not the same as the Proportion, or Ration of Space to Space, which they pervade: contrary to Michael Varro the Mathematici∣an.

455

13 But, that the moments or Equal degrees of Celerity, carry the same proportion, as the mo∣ments or equal degrees of Time, during the motion: according to the Illustrious Galilaeo.

456

14 Galilaeo's Grounds, Experience, and Reason.

457

15 The same Demonstrated.

458

16 The Physical Reason of that Proportion.

460

17 The Reason of the Equal Velocity of Bodies of very different weights, falling from the

same altitude; inferred from the same Theory.

ibid.

18 Gravity Distinguish't into Simple, and Ad∣jectitious.

461

19 The Rate of that superlative velocity with which a Bullet would be carried, in case it should fall from the Moon, Sun or region of the Fixed stars, to the Earth: and from each of those vast heights, to the Centre of the Earth.
