Fluid ounce
Fluid Flu"id, n. A fluid substance; a body whose particles move easily among themselves. [1913 Webster]

Note: Fluid is a generic term, including liquids and gases as species. Water, air, and steam are fluids. By analogy, the term was sometimes applied to electricity and magnetism, as in phrases electric fluid, magnetic fluid, though not strictly appropriate; such usage has disappeared. [1913 Webster +PJC]

{Fluid dram}, or {Fluid drachm}, a measure of capacity equal to one eighth of a fluid ounce.

{Fluid ounce}. (a) In the United States, a measure of capacity, in apothecaries' or wine measure, equal to one sixteenth of a pint or 29.57 cubic centimeters. This, for water, is about 1.04158 ounces avoirdupois, or 455.6 grains. (b) In England, a measure of capacity equal to the twentieth part of an imperial pint. For water, this is the weight of the avoirdupois ounce, or 437.5 grains.

{Fluids of the body}. (Physiol.) The circulating blood and lymph, the chyle, the gastric, pancreatic, and intestinal juices, the saliva, bile, urine, aqueous humor, and muscle serum are the more important fluids of the body. The tissues themselves contain a large amount of combined water, so much, that an entire human body dried in vacuo with a very moderate degree of heat gives about 66 per cent of water.

{Burning fluid}, {Elastic fluid}, {Electric fluid}, {Magnetic fluid}, etc. See under {Burning}, {Elastic}, etc. [1913 Webster]
