GREAT, a municipal and parliamentary borough of England, county of Buckingham, on the north bank of the Thames, 23 miles S. by E. of Aylesbury, and 31 W. by N. of London. The town consists of two principal streets at right angles to each other, and meeting in a large square, besides several smaller ones. The principal buildings are the town-hall, and the parish church, opened in 1836, and surmounted by a lofty spire. There are also places of worship for Wesleyan Methodists, Independents, Baptists, and Roman Catholics; national schools; charity schools; and other benevolent institutions. The river is here crossed by a handsome suspension bridge, with a span of 75 yards. The town possesses paper-mills and breweries; and the trade, which is considerable, consists chiefly of corn, coals, and timber. The markets have been discontinued; but large fairs are held here for horses and cattle; and there are races in August. Marlow returns two members to Parliament. Pop. of the municipal borough (1851) 4485; of the parliamentary borough (1851) 5523.
