re isomeric substances. Physical isomerism (Chem.), the condition or relation of certain (metameric) substances, which, while chemically identical (in that they have the same composition, the same molecular weights, and the same ultimate constitution), are yet physically different, as in their action on polarized light…

A crystalline hydrocarbon derivative, metameric with orcin, but produced artificially; -- called also cresorcin.

ctic acid, and obtained as a white crystalline substance having a neutral reaction. It is metameric with alanine.

An organic base, C9H6.N.CH3, metameric with quinaldine, and obtained by the distillation of cinchonine.

Any one of several metameric alkaloids, C5H3N.(CH3)2, of the pyridine series, obtained from bone oil as liquids, and having peculiar pungent odors. These alkaloids are also called respectively dimethyl pyridine, ethyl pyridine, etc.

The acid amide derived from malic acid, as a white crystalline substance metameric with asparagine.

Pertaining to, or designating, an acid of the ethylene series, metameric with fumaric acid and obtained by heating malic acid.

One of the serial segments, or metameres, of which the bodies of vertebrate and articulate animals are composed.

Other; duplicate, corresponding to; resembling; hence, metameric; as, meta-arabinic, metaldehyde.

The muscular system of one metamere of an articulate.

efix meaning new, recent, late; and in chemistry designating specifically that variety of metameric hydrocarbons which, when the name was applied, had been recently classified, and in which at least one carbon atom in connected directly with four other carbon atoms; -- contrasted with normal and iso-; as, neopentane; t…

A metameric segment of the cerebro-spinal nervous system.

One of a group of metameric hydrocarbons C9H20 of the paraffin series; -- so called because of the nine carbon atoms in the molecule. Normal nonane is a colorless volatile liquid, an ingredient of ordinary kerosene.

Any one of several metameric unsaturated hydrocarbons (C9H14) of the valylene series.

Any one of a series of metameric, unsaturated hydrocarbons C9H18 of the ethylene series.

Any one of a series of metameric hydrocarbons (C8H16) of the ethylene series. In general they are combustible, colorless liquids.

ce to optics. Optically active, Optically inactive (Chem. Physics), terms used of certain metameric substances which, while identical with each other in other respects, differ in this, viz., that they do or do not produce right-handed or left-handed circular polarization of light. -- Optically positive, Optically nega…

A metamere of the vertebrate skeleton; an osteomere; a vertebra. Owen.

Hydroxybutyric; designating any one of a group of metameric acids (C3H6.OH.CO2H).

Pertaining to, or designating, an organic acid metameric with malic acid.
