In 1887, John Bartholomew's Gazetteer of the British Isles described Islington like this:
Islington, parl. bor. and par. with ry. sta., Middlesex, in N. of London, 2½ miles N. of St Paul's, 3107 ac., pop. 282,865. Market-days, Tuesday, Wednesday, and Thursday; was a country vil. at the beginning of the 19th century; the Agricultural Hall, the largest building of the kind in London (capable of holding 50,000 people), is situated in the par. Islington returns 4 members to parl. (4 divisions - namely, North, West, East, and South - 1 member for each division); it was made a parl. bor. in 1885.
