UXBRIDGE, a market-town of England, in the county of Middlesex, 17 miles W.N.W. of St Paul's, London, on the Colne, here crossed by two good bridges. It extends about a mile along the road to Oxford, and is for the most part well built. The market-house consists of a good brick structure, supported by wooden pillars; and the parish church is an ancient edifice built of brick and flint. Uxbridge has a British school, school of industry, literary society, savings bank, flour-mills, malt-works, and a brick-field. A considerable trade in corn is carried on, and the Grand Junction Canal unites the town with London. In the time of the civil war, a fruitless negotiation for peace between the king and parliament was carried on at Uxbridge, and the house is still standing where the conferences were held. Pop. 3236.
