a colorless volatile highly inflammable liquid formerly used as an inhalation anesthetic

the fifth and highest element after air and earth and fire and water; was believed to be the substance composing all heavenly bodies

A medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether.

Supposed matter above the air; the air itself.

A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether. It is powerful solvent of fats, resins, and pyroxylin, but finds its chief use as an anaesthetic. Called also ethyl oxide.

Any similar oxide of hydrocarbon radicals; as, amyl ether; valeric ether.

A medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether.

Supposed matter above the air; the air itself.

A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether. It is powerful solvent of fats, resins, and pyroxylin, but finds its chief use as an anaesthetic. Called also ethyl oxide.

Any similar oxide of hydrocarbon radicals; as, amyl ether; valeric ether.

A mobile, very volatile, highly flammable liquid used as an inhalation anesthetic and as a solvent for waxes, fats, oils, perfumes, alkaloids, and gums. It is mildly irritating to skin and mucous membranes.

The upper purer air; a liquid anesthetic; the medium through which the rays of light and heat are transmitted.

1. A substance resulting from the action of an acid on an alcohol. 2. Ethyl or sulphuric ether (C2H5)2O; see oether. 3. A gas of extreme tenuity which is assumed to pervade all space as well as all solids and liquids, and to be the transmitter of the rays of heat and of light.

Volatile anesthetic, usually preferred to chloroform.

The clear, upper air: the subtile medium supposed to fill all space: a light, volatile, inflammable fluid.

A fluid medium supposed to fill all space; a class of volatile liquids.

A colorless volatile liquid, used as an anesthetic.

A supposed medium filling all space, and transmitting the vibrations of light, heat, and electricity.

The upper air.

An extremely subtile element conceived by the ancients to occupy the upper regions of space, and to be the primal fire-light-and life-centre of things; a subtile material element presumed to pervade all space, and to constitute the medium of the transmission of light and heat; a very light, volantile, and inflammable fluid, produced by the distillation of alcohol with an acid, especially with sulphuric acid.

An extremely fine fluid, supposed to fill all space beyond the limits of our atmosphere; a very light volatile and inflammable liquid, obtained from alcohol and an acid by distillation.

Aeher, Aether sulphuricus-e. Acetic, see Aether-e. Acitique, see Aether sulphuricus­-e. Azoteux, see Aether sulphuricus-e. Azoteux alcoolise, Spiritus aetheris nitrici.

The subtle fluid believed to fill all space.

Ethyl oxid, (C2H5)2O, volatile liquid used as an anesthetic, stimulant, anodyne, and solvent.

In physics, a supposititious medium of extreme tenuity pervading all space, whose vibrations serve, according to the undulatory theory, for the transmission of luminous, thermal, and electrical impulses.

A volatile liquid containing not less than 96 per cent, ethyl oxid [U. S. Ph] or 92 per cent. [Br. Ph.].

Primarily, any medium of extreme tenuity.

n. [Greek] A subtle fluid or medium supposed to pervade all space, and to be the medium of transmission of light and heat;—a very light, volatile, and inflammable fluid, produced by the distillation of alcohol with sulphuric acid.

An element more fine and subtle than air, air refined or sublimed; the matter of the highest regions above; a chymical preparation.
