    the nineteenth century the familiar processes of putrefaction and fermentation were not understood, and that the causes of infectious diseases were equally obscure, shows what an important change took place in man’s conception of the living world around him, when Pasteur and Koch founded bacteriology. The part played by bacteria in the causation of disease may be regarded as of surpassing importance, but the work done by them in other directions exerts a mighty influence upon the welfare of man- kind. Bacteria not only act as scavengers in de- stroying dead organic material, but they also change the form of important chemical elements, such as nitrogen and carbon, into substances which are available for the nutrition of the higher plants, thus pro^dng themselves as important in construc- tive as in destructive processes.
