fourth letter in the Grazco-Roman alphabets, was called in the Semitic Ian , guages daleth (hence Gr. delta, i.e., and in all probability its original ' hieroglyphic or picture form was a door). The Greek z 1 , in fact, yet preserves 'a recognizable resemblance to the door or opening of a tent, the kind of door most familiar to a nomadic people. D. belongs to the order of letters called denials (see L TEns, ALPILABET), t, d, 1h (in thin), lit (in thine), and in the corresponding words of sis :ter-languages is often exchanged with those of the same order or organ; thus: Ger. du, Eng. thou: Ger. tad, Eng. death; Lat. due-, Eng. tug; Lat. duo, Eng. two. A more remarkable interchange is that between d and 1, and d and r. See L and E. D seems to have been drawn into some words (to which it does not radically belong) by a kind of affinity for n, as Lat. cam's, Gr. kyon, Eng. hound; Lat. Eng. gender. Di followed by a vowel is sometimes transformed into J; as in Janus for Dianus; Journal from diur nal. Di followed by a vowel in Latin, has, in Italian, become z; and from MSS. and other evidence, we know that this sibilant sound of di prevailed, in the popular pronun ciation at least, while Latin was yet a living tongue. Thus, diabolus is found written
zaboitut, and Amazones, the Roman numeral for 500, arose out of the character ID. See NUMERALS.
D, in music, is the second note in the natural scale, and is a whole tone above C, to which it stands in mathematical proportion as 9:8, that is, when C vibrates eight times, 1) vibrates nine times. The whole tone from C to D is called the greater whole tone, 'being a comma larger than the next whole tone from D to E.
DAB, Platessa linuinda, a fish of the same genus with the plaice and flounder, and very much resembling them, hut easily distinguished from either of them by its more uniform and lighter-brown color, the roughness of its scaly surface, and its more curved lateral line, which rises into a high arch over the pectoral fin. It is common on all sandy parts of the British coasts, inhabits deeper water than the flounder, and does not, like it, enter the mouths of streams. It is known on the coasts of the firth of Forth as the salt-water fluke. It is preferred to the flounder for the table. It seldom exceeds 12 in. in length. A rather larger species of the same less plentiful sin the British coasts, is the LENroN D. or Smoot% D; (P. microcepliala). Its body is smooth, its color a pretty mixture of various shades of reddish-brown and yellow: its head and mouth are very
