To gather and bind into a sheaf or sheaves; hence, to collect. Ashmole.

In brief outline it is as follows: Animal cells and bacteria are complex aggregations of molecules, which are themselves complex. Complex molecules react with one another through certain of their side chains, but only when these side chains have a definite correspondence in structure (this account for the specific act…

ent (Spalax typhlus), native of Russia and Asia Minor. It has the general appearance of a mole, and is destitute of eyes. Called also mole rat.

A kind of beverage; sherbet. Smolett.

A curious American mole (Condylura cristata) having the nose expanded at the end into a stellate disk; -- called also star-nosed mole.

int, of the fat, as in mutton tallow. Chemically, it is a compound of glyceryl with three molecules of stearic acid, and hence is technically called tristearin, or glyceryl tristearate.

Pertaining to, or illustrating, the hypothetical space relations of atoms in the molecule; as, a stereo-chemic formula.

Any atom, group, or radical substituted for another, or entering a molecule in place of some other part which is removed.

That property, due to molecular forces, which exists in the surface film of all liquids and tends to bring the contained volume into a form having the least superficial area. The thickness of this film, amounting to less than a thousandth of a millimeter, is considered to equal the radius of the sphere of molecular act…

ine, soft, thick cloth of wool mixed with silk or cotton; a sort of twilled fustian, like moleskin. Swan's-down cotton. See Cotton flannel, under Cotton.

A genus of small insectivores including the common European mole.

The duck mole.

groups, or radicals, which are regarded as having different functions or relations in the molecule; thus, sodic hydroxide, NaOH, is a ternary compound.

Capable of neutralizing four molecules of a monacid base; having four hydrogen atoms capable of replacement by bases; quadribasic; -- said of certain acids; thus, normal silicic acid, Si(OH)4, is a tetrabasic acid.

Capable of neutralizing four molecules of a monobasic acid; having four hydrogen atoms capable of replacement ba acids or acid atoms; -- said of certain bases; thus, erythrine, C4H6(OH)4, is a tetracid alcohol.

rbon, C14H30, of the marsh-gas series; -- so called from the fourteen carbon atoms in the molecule.

ing to the marsh-gas series; -- so called from having twenty- four atoms of carbon in the molecule.

Consisting of four atoms; having four atoms in the molecule, as phosphorus and arsenic.

l hydrocarbon, C4H4, analogous to benzene; -- so called from the four carbon atoms in the molecule. Tetrol phenol, furfuran. [Obs.]

An oxide having four atoms of oxygen in the molecule; a quadroxide; as, osmium tetroxide, OsO.
