Excerpt from The Elements of Chemical Arithmetic: With a Short System of Elementary Qualitative Analysis

A mass of matter is any portion of matter appreciable by the senses.

A molecule is the smallest particle of matter into which a body can be divided Without losing its identity; or it is the smallest portion of matter which can exist by itself.

An atom is a still smaller particle produced by the division of a molecule; or it is the smallest portion of matter that can go into combination.

Examples. The sun and a grain of sand are masses of matter. The smallest particle of salt which can exist and which exhibits the properties of salt is a molecule. The minute particles of Chlorine and sodium which com pose the molecule of salt are atoms.
