in Physics, a minute particle, or physical atom, such as a natural body is composed of. By this word is not meant the elementary particles, nor hypothetical principles of chemists; but those particles, whether of a simple or compound nature, the parts of which will neither be dissolved nor dissipated by ordinary degrees of heat.

**CORPUSCULAR PHILOSOPHY** is that method of philosophising which endeavours to explain things, and to account for the phenomena of nature, by the motion, figure, rest, position, attraction, or repulsion of the corpuscles, or the minute particles of matter.
