Geological map, 4 sheets, engraving, hand coloured to show geology, Plan of the County of Westmorland, scale about 1 1/4 inches to 1 mile, surveyed 1823-25 by Thomas Hodgson, engraved by W Gardner, Harpur Street, London, published by Thomas Hodgson, Lancaster, Lancashire, 1828; geologically coloured probably by Jonathan Otley, after 1835.
Fitted round the vignette lower left is a table of strata added in manuscript. Note the use of 'Silurian' which was not in use till 1835.
Comparison of equally formal lettering on other maps by Jonathan Otley, in a private collection, makes it very likely that the geological colouring is by him.
