GAUGE n.
uge, an instrument or contrivance for indicating the degree of saltness of water from its specific gravity, as in the boilers of ocean steamers. -- Sea gauge, an instrument for finding the depth of the sea. -- Siphon gauge, a glass siphon tube, partly filled with mercury, -- used to indicate pressure, as of steam, or…
GELATIN; GELATINE n.
hem.) Animal jelly; glutinous material obtained from animal tissues by prolonged boiling. Specifically (Physiol. Chem.), a nitrogeneous colloid, not existing as such in the animal body, but formed by the hydrating action of boiling water on the collagen of various kinds of connective tissue (as tendons, bones, ligament…
GLUCINUM n.
A rare metallic element, of a silver white color, and low specific gravity (2.1), resembling magnesium. It never occurs naturally in the free state, but is always combined, usually with silica or alumina, or both; as in the minerals phenacite, chrysoberyl, beryl or emerald, euclase, and danalite. It was named from its…
GOLD n.
exchange. It has a characteristic yellow color, is one of the heaviest substances known (specific gravity 19.32), is soft, and very malleable and ductile. It is quite unalterable by heat, moisture, and most corrosive agents, and therefore well suited for its use in coin and jewelry. Symbol Au (Aurum). Atomic weight 19…
GRANGER RAILROADS; GRANGER ROADS n.
ilroads whose traffic largely consists in carrying the produce of farmers or grangers; -- specifically applied to the Chicago & Alton; Chicago, Burlington & Quincey; Chicago, Rock Island & Pacific; Chicago, Milwaukee & St. Paul; and Chicago & Northwestern, railroads. [U. S.].
GRAVITY n.
uteness. Center of gravity See under Center. -- Gravity battery, See Battery, n., 4. -- Specific gravity, the ratio of the weight of a body to the weight of an equal volume of some other body taken as the standard or unit. This standard is usually water for solids and liquids, and air for gases. Thus, 19, the specifi…
