Producing fumes, or vapors. Cadet's fuming liquid (Chem.), alkarsin. -- Fuming liquor of Libsvius (Old Chem.), stannic chloride; the chloride of tin, SnCl4, forming a colorless, mobile liquid which fumes in the air. Mixed with water it solidifies to the so-called butter of tin. -- Fuming sulphuric acid. (Chem.) Same…

An impure resin of turpentine, hardened on the outside of pine trees by the spontaneous evaporation of its essential oil. When purified, it is called yellow pitch, white pitch, or Burgundy pitch.

fluids supposed to be permanently elastic, as oxygen, hydrogen, etc., in distinction from vapors, as steam, which become liquid on a reduction of temperature. In present usage, since all of the supposed permanent gases have been liquified by cold and pressure, the term has resumed nearly its original signification, and…

-- Vacuum gauge, a species of barometer for determining the relative elasticities of the vapor in the condenser of a steam engine and the air. -- Water gauge. (a) A contrivance for indicating the height of a water surface, as in a steam boiler; as by a gauge cock or glass. (b) The height of the water in the boiler.…

ron blast furnace by reducing its temperature so far that it will not remain suspended as vapor in the blast current, but will be deposited as snow in the cooling apparatus. The resultant uniformly dehydrated blast effects great economy in fuel consumption, and promotes regularity of furnace operation, and certainty of…

An apparatus in which vapor or gas is formed from a liquid or solid by means of heat or chemical process, as a steam boiler, gas retort, or vessel for generating carbonic acid gas, etc.

(him) that he lies. -- To give line.

h masses of ice precipitated from the clouds, where they are formed by the congelation of vapor. The separate masses or grains are called hailstones. Thunder mixed with hail, Hail mixed with fire, must rend the Egyptian sky. Milton.

Produced by, or like, breath; vaporous. Boyle.

Light vapor or smoke in the air which more or less impedes vision, with little or no dampness; a lack of transparency in the air; hence, figuratively, obscurity; dimness. O'er the sky The silvery haze of summer drawn. Tennyson. Above the world's uncertain haze. Keble.

re which is recognized in various effects, but especially in the phenomena of fusion and evaporation, and which, as manifested in fire, the sun's rays, mechanical action, chemical combination, etc., becomes directly known to us through the sense of feeling. In its nature heat is a mode if motion, being in general a for…
