So we endeavour, by Chemistry, to find out the nature of various bodies, their changes, and the results. In nature we have simple and compound bodies. The former are called Elements. We must not confuse these elements with the so-called elementsearth, air, fire, and water. These are really compound bodies. An element is a substance or a gas which is not composed of more than one constituent; it is itselfa compound of perfectly identical particles.

These bodies are divided into non-metallic and metallic elements, and all bodies are composed of them, or are these bodies[Pg 308] themselves. The list is as follows.
