HY-DRO-CY-AN'IC, a. [Gr. υδωρ, water, or rather hydrogen, and κυανος, blue.]

An acid whose base is hydrogen, and its acidifying principle cyanogen; more correctly Cyanohydric. This acid is one of four or five different compounds that have been called prussic acid.

Pertaining to the force or pressure of water.

HY-DRO-DY-NA'MICS, n.

That branch of natural philosophy which treats of the phenomena of water and other fluids, whether in motion or at rest; of their equilibrium, motion, cohesion, pressure, resistance, &c. It comprehends both hydrostatics and hydraulic. Ed. Encyc.

HY-DRO-FLU'ATE, n.

A compound of hydrofluoric acid and a base. Better Fluohydrate.

HY-DRO-FLU-OR'IC, a. [Gr. υδωρ, water, and fluor.]

Consisting of fluorin and hydrogen. The hydrofluoric acid is obtained by distilling a mixture of one part of the purest flour spar in fine powder, with two of sulphuric acid. More correctly Fluohydric. Brande.

HY'DRO-GEN, n. [Gr. υδωρ, water, and γενναω, to generate; so called as being considered the generator of water.]

In chimistry, a gas which constitutes one of the elements of water, of which it is said by Lavoisier to form fifteen parts in a hundred; but according to Berzelius and Dulong, hydrogen gas is 11.1 parts in a hundred, and oxygen 88.9. Hydrogen gas is an aeriform fluid, the lightest body known, and though extremely inflammable itself, it extinguishes burning bodies, and is fatal to animal life. Its specific gravity is 0.0694, that of air being 1.00. In consequence of its extreme lightness, it is employed for filling air balloons. Lavoisier. Brande.
