A spectro-electric tube in which the decomposition of a liquid by the passage of an electric spark is observed. Knight.

carbohydrate resembling gelose, found in the seeds of leguminous plants, and yielding on decomposition several sugars, including galactose.

A white, crystalline sugar, C6H12O6, isomeric with dextrose, obtained by the decomposition of milk sugar, and also from certain gums. When oxidized it forms mucic acid. Called also lactose (though it is not lactose proper).

oric acid, and present in bile united with cholic acid. It is also formed from gelatin by decomposition with acids. Chemically, it is amido-acetic acid. Called also glycin, and glycocin.

, CN3H5, formed by the oxidation of guanin, and also obtained combined with methyl in the decomposition of creatin. Boiled with dilute sulphuric acid, it yields urea and ammonia.

A white, crystalline substance having a sweetish taste, obtained by the decomposition of hesperidin, and regarded as a complex derivative of caffeic acid.

A soluble ferment occurring in the animal body, to the presence of which many normal decompositions and synthetical processes are supposed to be due.

That portion of the soil formed by the decomposition of animal or vegetable matter. It is a valuable constituent of soils. Graham.

The main constituent of the walls of hydatid cysts; a nitrogenous body, which, by decomposition, yields a dextrogyrate sugar, susceptible of alcoholic fermentation. Gamgee.

nt light that appears, in the night, over marshy ground, supposed to be occasioned by the decomposition of animal or vegetable substances, or by some inflammable gas; -- popularly called also Will-with-the-wisp, or Will-o'-the-wisp, and Jack-with-a- lantern, or Jack-o'-lantern.

Incapable of being together without mutual reaction or decomposition, as certain medicines. Incompatible terms (Logic), terms which can not be combined in thought.

Not decomposable; incapable or difficult of decomposition; not resolvable into its constituents or elements.

Incapableness of decomposition; stability; permanence; durability.

Not destructible; incapable of decomposition or of being destroyed. -- In`de*struc"ti*ble*ness, n. -- In`de*struc"ti*bly, adv.

iolet luster when rubbed. Indigo does not exist in the plants as such, but is obtained by decomposition of the glycoside indican.

lements which appear at the respective poles when a body is subjected to electro-chemical decomposition. Cf. Anion, Cation.

A white, crystalline, sugarlike substance, obtained by the decomposition of certain glucosides, and intermediate in nature between the hexacid alcohols (ductile, mannite, etc.) and the glucoses.

o form the paste of porcelain; China clay; porcelain clay. It is chiefly derived from the decomposition of common feldspar.

substance, and, unlike elastin, is not dissolved even by gastric or pancreatic juice. By decomposition with sulphuric acid it yields leucin and tyrosin, as does albumin. Called also epidermose.

Pertaining to, or designating, an acid obtained from the urine of dogs. By decomposition the acid yields a nitrogenous base (called kynurin) and carbonic acid. [Written also cynurenic.]
