In a more restricted sense, that which occupies space, is denominated Matter. In the most extended signification, matter is that which in any way becomes cognoscent to our senses. 4.

The space which a body occupies, according to its length, breadth, and depth, gives the idea of its figure. The bulk of a body is named its volume. 6.
