The Atlas of the British Isles
The most prominent feature are the bright colours for the Parliamentary Divisions, as used from 1885, which retained Colchester as a separate Division. There is no plate number in the top right corner on this map, unlike the 1886 version, despite a centre fold showing that this came from an atlas.
Scale correct at 10 miles = 63mm, or 4.0 miles/inch, ie 1:255,000.
The railway is shown from Southend to Shoeburyness (opened 1884) and from Barking to Upminster and Hornchurch (opened 1885), but the line beyond that towards Pitsea (also authorised 1882, opened 1885) is shown only as a dashed line (different from the parallel lines of 1884), and passing to the south of Laindon; there are also dashed lines from Romford to Upminster to Grays Thurrock (both authorised 1883, and opened 1893/92). There is no explanation of the dashed railway line in the key - in 1895 these are explained as "in progress".
