the government to carry out a boundary survey of Ireland. He was to mark the boundaries of every county, barony, civil parish and townland in preparation for the first Ordnance Survey. He was also called upon to assist in the preparation of a parliamentary Bill to provide for the general valuation of Ireland. This Act was passed in 1826, and he was appointed Commissioner of Valuation in 1827, but did not start work until 1830 when the new 6" maps became available from the Ordnance Survey and which he was required to use as provided for by statute. He continued to work on this until 1868. On Griffith's valuation the various local and public assessments were made. His extensive investigations furnished him with ample material for improving his geological map, and the second edition was published in 1835. The third edition on a larger scale (1 in. to 4 m.) was issued under the Board of Ordnance in 1839, and it was further revised in 1855. For this work and his other services to science, he was awarded the Wollaston medal by the Geological Society in 1854. In 1850 he was made chairman of the Irish Board of Works, and in 1858 he was created a baronet. After research in the 20th century, is now known that to a large extent the improvements of detail in the maps which Griffith was praised for and the geological research for Griffith's papers were down to Patrick Ganly, whose pioneering work went entirely uncredited by Griffith. He died at his residence, 2 Fitzwilliam Place in Dublin, on 22 September 1878 in his 95th year. At the time of his death, he was the oldest surviving fellow of the Geological Society of London and was the last survivor of the long-since disbanded Royal Irish Regiment of Artillery. He was buried alongside his wife, Maria Jane (née Waldie m. 21 Sep 1812) in Mount Jerome Cemetery, Harold's Cross, Dublin; on his grave is the epitaph: Not slothful in business, fervent in spirit, Serving the Lord. Family In 1812 he married Maria Jane Waldie of Hendersyde Park in Kelso. They had one son, Sir George Richard Waldie-Griffith, 2nd Baronet.
