from The Century Dictionary.

  • noun A substitute for yeast used for leavening bread, consisting of a preparation of soda, phosphates, and other substances, in the form of a powder; a baking-powder.
  • noun While this term is, in the United States, generally understood to mean one of the baking-powder mixture's used as substitutes for yeast, it has been sometimes applied to yeast itself obtained as a result of alcoholic fermentation, freed from water by pressure, washed with acetone and then with ether, and dried in pulverulent form by spreading it out on absorbent paper at ordinary temperature.
