or PHONETICAL, representing sound; pertaining to the representation of sounds; a term applied to alphabetic or literal characters which represent sounds, as a, b, c; as opposed to ideographic, which represent objects or symbolize abstract ideas, as in Egyptian hieroglyphics. Phonetic spelling, a system of spelling in which the words are spelled exactly as they are pronounced, the sounds being represented by characters each of which represents a single sound. Phonetic printing was first suggested by Isaac Pitman, of Bath, England, and reduced to a system by him in conjunction with A. J. Ellis, in the years 1843-1846. Since that time many systems of phonetic spelling have been proposed and several are used by stenographers in the United States.

a description of the sounds uttered by the organs of speech. Also the representation of sounds by certain characters, each of which represents sound one sound, and always the same . Its special application is to alphabetical writing, in which sounds or articulations are represented by signs or letters, as opposed to the system in which the representation is by ideas, symbols, or of writcipher. Specifically, a method ing, or graphically representing language, invented by Isaac Pitman, of Bath, England. See SHORTHAND. Also means the art of using, or registering by of, the phonograph; the construction of phonographs.

He is represented as a monster with one eye in the middle of his forehead. Ulysses was his captive, but escaped by putting a fire-brand in the monster's eye. 2026 Editor's Note: This entry appears to conflate the sea god Phorcys with the Cyclops Polyphemus, who was famously blinded by Odysseus. In Greek mythology, Phorcys is typically described as a son of Pontus and Gaia and the father of various monsters by his wife Ceto. While he is sometimes depicted as a merman with crab-claw legs, he is distinct from the Phrygian leader of the same name who was killed by Ajax during the Trojan War. (Ed: BR 2026-07-07)

that branch of science which deals with the chemical of fact that changes in the brought about by the agency or structure of matter can about by light has been of probably, since the century, Schultze ob- 1727, that silver chloride, when exposed to sunlight, changed from creamy white a to purplish brown. Generally speaking, the rate of chemical action is proportional to the intensity of the light, but the exact determination of the activity of light was first suggested by John W. Draper, of New York University, who measured the rate of com bination brought about by light in a mixture of hydrogen and chlorine. Later, Bunsen and Roscoe made use of a photographic film, measuring the time required to darken the film to a standard tint. The action of light is not confined to any particular wave length, but the most active are the violet and ultraviolet, or so-called actinic, rays. Red light is, for most practical purposes, inactive, and this fact is made use of in photographic dark rooms in which white light is excluded and red lamps or windows employed. The action of light produces on photographic plates and bromide papers an effect which is not immediately visible, but can be made so by further action of a chemical known as a developer.
