Excerpt from The Popular Educator, Vol. 2: A Complete Encyclopaedia of Elementary, Advanced and Technical Education The most minute particle, which even the microscope can only just discern, may contain millions of these atoms, so that they are far beyond the reach of the recognition of our senses. A molecule (a little mass) will bear a definite meaning in these pages - namely, the least particle of a compound body which is capable of existing by itself. In fact, it is the ultimate particle of such a body. Thus we shall find that water is composed of two atoms of hydrogen and one of oxygen hence the molecule of water would be a group of these three atoms.
