This work is an attempt to reveal to the reader those living beings of the Invisible World which most concern us. The author is not aware that any other work, similar in plan and scope, has been published. Fragmentary parts of the general subject have been treated, but even these have usu ally appeared in so technical terms as to be of little, if any, avail to the general public. The aim here has been to cover the entire field, and in so plain and simple language that whoever reads may understand.

With this aim in view, Microbes In General are first considered, their nature, functions, origin.
