THE GROWTH OF DIFFERENT ORGANISMS IN A STATE OF PURITY: THEIR AUTONOMY.
§ I. Growth of _Penicillium glaucum_ and _Aspergillus glaucus_ in a state of purity.—Proofs that these fungoid growths do not become transformed into the alcoholic ferments of beer or wine.—Preliminary inquiry into the cause of fermentation 86
§ II. Growth of _Mycoderma vini_ in a state of purity.—Confirmation of our original conjectures as to the cause of fermentation.—_Mycoderma vini_ does not change into yeast, although it may give rise to fermentation 108
§ III. Growth of _Mycoderma aceti_ in a state of purity 121
§ IV. Growth of _Mucor racemosus_ in a state of purity.—Example of life more active and lasting when removed from the influence of air 127
