Physical science treats of the properties and phenomena of the matter of which these bodies are composed. Matter is anything whose existence is revealed to us by our senses. The properties of a body are the peculiar qualities by which it makes itself known to us; as color, solidity, odor, taste, etc. Physics is that branch of physical science which treats of the phenomena presented to us by bodies or masses of matter as such. Chemistry is that branch of physical science which treats of the ultimate composition of bodies, and the changes which this composition may undergo.
