What office in Nature do bacteria seem to serve? Give the theory in regard to propagation of special disease germs. Do they always cause disease when taken into the body? [Footnote: Of the immense number and variety of microorganisms found in Nature, only very few are disease producing. Dr. Austin Flint says in _The Forum_, for December, 1888: "It is probable that future investigations into the physiology of digestion, will show that bacteria play an important part in this function. Pasteur has recently isolated no less than seventeen different microorganisms in the mouth, which were not destroyed by the gastric juice. Some of these dissolved albumen, gluten, and caseine, and some transformed starch into sugar. Bacteria normally exist in great number and variety in the intestines, although the part which they take in intestinal digestion has not been accurately determined."--The number of spores introduced into the human system by respiration, when the health is perfectly sound, has been estimated at three hundred thousand a day.] 302.
