Body; extended sub- stance; that which is visible or tangible to the perceptive senses; that which fills space, and of which the macrocosm of natui-e, and all essential bodies consists. That which possesses the properties whose existence is revealed to us by our senses; that part of the universe which is neither mind nor force — substance. We know nothing of the essential or inti- mate nature of matter, and are only acquainted with its existence through its essential properties, which are: Divisi- bility, impenetrability, porosity, compres- sibility; to which may be added extension and figure, which belong also to space, and form the subject of geometry. The contingent properties oi matter are mo- bility and weight. Matter in every form is capable of being moved from one place to another; and every substance is sub- ject to the attraction of gravitation. But motion has reference to space, and weight to the attraction of other matter. The above are the general properties of mat- ter, on which physical investigations de- pend. There are, however, various other qualities belonging to particular sub- stances, or to matter in particular states, the consideration of which is important in mechanical philosophy. A^mong these the principal are elasticity, fluidity, hard- ness, rigidity, solidity.
