THE RELATION OF ALCOHOL TO LIVING PROTOPLASM.
(a) The Source of Alcohol.
—Ethyl alcohol is one of the normal products of metabolism of the yeast plant. Most species of white mold form alcohol under abnormal conditions. The conditions which lead to a formation of alcohol by the white mold, lead also to a marked increase in the formation of alcohol by yeast.The yeast plant is a fungus and in common with other fungi reproduces by means of spores. The yeast plant possesses another method of reproduction, gemmation or budding. This method is used when all conditions are favorable to vegetative growth.The fungi belong to the lowest sub-kingdom of plants, and are distinguished morphologically by absence of root, stem and leaf; and physiologically by the absence of chlorophyl—the green coloring matter of leaves and stems.According to the plan of nature, only those organisms which possess chlorophyl are able
