FIRST EDITION, first issue of the second published geological map and railway map of Ireland. Griffith’s first geological map of Ireland, on a scale of 1 inch to 10 miles, was published in July 1838 to accompany the second report of the Irish Railway Commission. The publication of the present much larger map, on a scale of 1 inch to 4 miles, was delayed but it finally appeared in March 1839. The present copy is uncoloured geologically, but it appears that such copies are very rare and were only coloured to order. “It was remarkably detailed…” (DSB). The first railway map of Ireland was contained in the same second Report of the Irish Railway Commission (the first Report does not appear to have included a map), and in the same way was succeeded by the present map. “Title, left-hand top corner. Legend with 26 tablets in left-hand margin. Signed: ‘Dublin, March 28th, 1839 Richard Griffith.’ References, authorities and scales in lower margin. Below these is the MS. signature of Thos. A. Larcomb, Lieut. R.Eng. (in charge of the Trigonometrical Survey of Ireland at this time and responsible for the engraved basis of the present map and plate)… Coloured examples of this map have not been seen, but an uncoloured copy is in the Library of the Geological Survey, London” (Davis).
