Chem.: A term used to denote the elements or compounds from which a more complex substance is obtained. Thus ethyl, alcohol, and acetic acid are the generators of acetic ether; and benzoic acid and glycocoll are the generators of hippuric acid. By the action of acids or alkalies these substances can be resolved into their generators, and so the constitution of a complex body can be determined; thus, Lecithin, a constituent of the brain, has the formula C4H90N PO; it has six generators, gly cerin, phosphoric acid, stearic acid, glycol, methyl alcohol, and ammonia; therefore it is found to be a dis tea rate glycerophosphate of choline, and choline has been found to be a trimethyl oxyethyl ammonium hydrate (CH3)3N CH2OH CH OH. 3. Distill .: A retort in which volatile hydrocarbons are distilled from liquid or solid matters. 4. Music: A ground note, fundamental ba , root, derivative. The principal sound or sounds by which others are produced, as the lower c for the treble of the harpsichord, which beside its octave will strike an attentive ear with its twelfth above or G in alt, and with its fifteenth above or c in alt. 5. Steam : A ve el in which steam is generated from water, for use in a steam-engine, a heating apparatus, . The term was first applied to the Perkins steam-boiler, in which water in small quantity was heated to a high temperature. It is now specifically applied to a cla of instantaneous generators. The name is now rapidly coming into use for all apparatus for generating steam, being held to be more correct than the usual term. [STEAM-BOILER.]
