I have endeavored to present the subject in a condensed but general way without burdening you with technical details of species, genera or life history. The subject is a vast one and to which the best minds of the scientific world are devoting themselves. To those who are or may become interested in bacteriology and particularly to those who study the relation of these germs to disease, is held forth the reward which is sure to come to those who work persistently and intelligently.
The method which I shall employ to-night is eclectic. Doubtless each investigator will find fault with some parts of the process and perhaps suggest a better one. The following, however, has in my hands worked well and given entire satisfaction, so far as I know, to those who were and are most interested.
The apparatus necessary is as follows:
One two-inch glass funnel.
One package filter papers to fit same.
Four medium size test tubes.
Two glass or porcelain staining glasses.
One glass or agate mortar and pestle.
One cover holder.
One pair pincetts.
