Because of the Dec. 12^th,1835 date, this map is often partially attributed to James Knipe, who had been in partnership with the Walkers but fell out with them after their first and only jointly produced map which covered only England and Wales, also dated Dec. 18^th, 1835, This is the first edition, 2^nd issue, of this map, distinguishable by the relocation of tidal information from the left to the right side of the map, and likely issued early in 1836.  Refer to Toland et al, ‘The Life and Works of James Alexander Knipe’, Earth Sciences History, v.32, n.2. p.302.
