A system of courts of the United States (one in each circuit) created by act of congress of March 3, 1891 (U. S. Comp. St 1901, p. 488), composed of the circuit justice, the circuit judge, and an additional circuit judge appointed for each such court, and having appellate jurisdiction from the circuit and district courts except in certain specified classes of cases. Circuitus est evitandus; et boni judi cis est lites dirimere, ne lis ex lite oria tur. 5 Coke, 31. Circuity is to be avoided; and it is the duty of a good judge to determine litigations, lest one lawsuit arise out of another.
