 Meth·yl n.  Chem. A univalent hydrocarbon radical, CH3-, not existing alone but regarded as an essential residue of methane, and appearing as a component part of many derivatives; as, methyl alcohol, methyl ether, methyl amine, etc. [Formerly written also methule, methyle, etc.]
 Methyl alcohol Chem., a light, volatile, inflammable liquid, CH3.OH, obtained by the distillation of wood, and hence called wood alcohol or wood spirit; tecnically referred to as methanol; -- called also methol, carbinol, etc.
 Methyl amine Chem., a colorless, inflammable, alkaline gas, CH3.NH2, having an ammoniacal, fishy odor.  It is produced artificially, and also occurs naturally in herring brine and other fishy products.  It is regarded as ammonia in which a third of its hydrogen is replaced by methyl, and is a type of the class of substituted ammonias.
 Methyl ether Chem., a light, volatile ether CH3.O.CH3, obtained by the etherification of methyl alcohol; -- called also methyl oxide or dimethyl ether.

 Al·co·hol n.
 1. An impalpable powder. [Obs.]
 2. The fluid essence or pure spirit obtained by distillation. [Obs.]
 3. Pure spirit of wine; pure or highly rectified spirit (called also ethyl alcohol or ethanol, CH3.CH2.OH); the spirituous or intoxicating element of fermented or distilled liquors, or more loosely a liquid containing it in considerable quantity. It is extracted by simple distillation from various vegetable juices and infusions of a saccharine nature, which have undergone vinous fermentation.
 Note: [The ferementation is usually carried out by addition of brewer's yeast, Saccharomyces cerevisiae to an aqueous solution containing carbohydrates.]
 Note: ☞ As used in the U. S. “Pharmacopœia,” alcohol contains 91 per cent by weight of ethyl alcohol and 9 per cent of water; and diluted alcohol (proof spirit) contains 45.5 per cent by weight of ethyl alcohol and 54.5 per cent of water.
 4. Organic Chem. A class of compounds analogous to vinic alcohol in constitution. Chemically speaking, they are hydroxides of certain organic radicals; as, the radical ethyl forms common or ethyl alcohol (C2H5.OH); methyl forms methyl alcohol (CH3.OH) or wood alcohol; amyl forms amyl alcohol (C5H11.OH) or fusel oil, etc.
