DISCO 374 DISEASE Church, then living in western Penn- sylvania, issued a "Declaration and Address" deploring the divided state of the Church, and urging as the only remedy a complete restoration of apos- tolic Christianity and the rejection of all human creeds and confessions of faith. The Christian Association of Washington, Pa., was formed for the purpose of pro- moting the principles set forth in this "declaration." Mr. Campbell's son, Alex- ander, led the new movement. It was not the intention of the Campbells to form a distinct religious body, but to effect the proposed reforms in the Churches. Opposition forced them to act independently and the first Church was organized at Brush Run on May 4, 1811. The Disciples accept the Bible as their only rule of faith and practice. They re- ject infant baptism and adopt believers* immersion only. They observe the Lord's Supper each first day of the week, and practically accept and exalt the doctrine of the divinity of Christ. Their Church polity is congregational, though they fre- quently hold conventions in the interest of world-wide missions, but not for leg- islative purposes. They maintain college and numerous benevolent and educational organizations. They support mission- aries in India, China, Japan, Africa, the Philippines, Cuba, Porto Rico, Mexico, Scandinavia, and Turkey. In 1919, the Disciples of Christ throughout the world numbered about 1,400,000. DISCO, an island on the W. coast of Greenland, under the parallel of 70° N. It is mountainous, reaching a height of 3,000 feet; has a total length of about 90 miles; and contains much excellent coal. The harbor of Godhavn is on the S. coast. DISCOBOLUS, in classical antiquity, a thrower of a discus, or quoit; a quoit- player; specifically: the name given to the famous Greek statue of the quoit- thrower, preserved among the Townley Marbles in the British Museum. In ich- thyology a name given by Cuvier to his third family of soft-finned teleostean fishes, having the ventral fins under the pectoral. The name is derived from the ventral fins forming a disk on the under surface of the body, by which the fishes are enabled to catch hold on the points of rocks. DISCORD, in music, a combination of notes which produces a certain restless craving in the mind for some further combination upon which it can rest with satisfaction. Discords comprise such chords as contain notes which are next to each other in alphabetical order, and such as have augmented or diminished inter- vals, with the exception in the latter case of the chord of the sixth and third on the second note of any key. The changed combination which must follow them, in order to relieve the sense of pain they produce, is called the resolution. In fine arts, a term applied to paintings when there is a disagreement of the parts or coloring. DISCOUNT, a deduction made in the payment of a bill or settlement of an account for ready or prompt pasnnent; a sum deducted at a certain rate per cent, from the credit price of any article in consideration of prompt payment. The term discount is applied both to the amount deducted and the rate per cent, at which the deduction is calculated or allowed. Discount in banking is a charge made at a certain rate per cent, for the interest of money advanced on a bill or other document due at some future time. This charge the discounter deducts from the amount of the bill, handing over the balance to the borrower; a deduction from the present value of a security, the payment of which is postponed. The rate of discount depends on, and is regu- lated by, the market value of money. DISCUS, DISC, or DISK, among the Greeks and Romans a quoit of stone or metal, convex on both its sides, some- times perforated in the middle. The players aimed at no mark, but simply tried to throw the quoit to the greatest possible distance. It was sometimes furnished with a thong of leather to as- sist in the throwing. The throwing of the discus was a notable feature of the revival of the Olympian Games at Athens in 1896. In these games the discus- throwing event was Avon by Robert Garrett, of Princeton University, who far outclassed all the foreign competitors. DISEASE, any alteration of the nor- mal vital processes of the body under the influence of some unnatural or hurtful condition, called the morbific cause. If accompanied by change of structure, it is called organic or structurel; if not, it is said to be functional. The history of disease includes: (1) Symptomatology, or semeiology, the morbid phenomena or symptoms; (2) etiology, or causes of disease, the specific agents or causes gen- erating or producing disease; (3) the special locality or seat of structural dis- ease: (4) the nature and extent of mor- bid alterations, or lesions, or the stamps, anatomical signs, or evidence of its ex- istence, in connection with its symptoms, causes, and course during life — morbid anatomy; and (5) morbid histology, or the elementary constituents of disease- products.
