An accumulation of liquid within the cavity of the cranium, especially within the ventricles of the brain; dropsy of the brain. It is due usually to tubercular meningitis. When it occurs in infancy, it often enlarges the head enormously.

nation of, hydrogen and cyanogen. Hydrocyanic acid (Chem.), a colorless, mobile, volatile liquid, HCN, having a characteristic peach-blossom odor. It is one of the most deadly poisons. It is made by the action of sulphuric acid on yellow prussiate of potassium (potassium ferrocyanide), and chemically resembles hydrochl…

Pertaining to, or derived from, the dynamical action of water of a liquid; of or pertaining to water power. Hydrodynamic friction, friction produced by the viscosity of a liquid in motion.

An instrument to measure the velocity of a liquid current by the force of its impact.

uohydric; as, hydrofluoric acid. Hydrofluoric acid (Chem.), a colorless, mobile, volatile liquid, HF, very corrosive in its action, and having a strong, pungent, suffocating odor. It is produced by the action of sulphuric acid on fluorite, and is usually collected as a solution in water. It attacks all silicates, as gl…

Not capable of being reduced to the form of a liquid by pressure; -- said of any gas above its critical point; -- also particularly of oxygen, hydrogen, nitrogen, and carbon monoxide, formerly regarded as incapable of liquefaction at any temperature or pressure.

or incapable of reduction in volume by pressure; -- formerly supposed to be a property of liquids. The incompressibility of water is not absolute. Rees.
