that did not deter Constable from undertaking further publishing projects. In 1854 he began publishing the complete works (in eleven volumes and edited by Sir William Hamilton; 1854-1877) of the Scottish philosopher and mathematician Dugald Stewart. In the same year Constable launched the popular school series known as Constable's Educational Series (which featured such books as J. D. Morell's A Grammar of the English Language Together with an Exposition of the Analysis of Sentences, James Clyde's Elementary Geography and James Currie's The Elements of Musical Analysis). Also in 1854 he launched the series known as Constable's Miscellany of Foreign Literature. Some of the other notable works published by Thomas Constable included the Letters of Calvin Compiled from the Original Manuscripts and Edited with Historical Notes (1855), Giovanni Ruffini's novels such as Lorenzo Benoni Or Passages in the Life of an Italian (1853), The Paragreens on a Visit to the Paris Universal Exhibition (1856) and Doctor Antonio: A Tale (1858), and the earlier works of John Brown, M.D., such as Rab and his Friends (1859). In 1853 much of Thomas Constable's printing work consisted of Bible printing. In that year he also extended his printing clientele: rather than just printing for the local Scottish market, he entered the London market and began to print books for London publishers. T. & A. Constable Ltd Thomas Constable continued publishing until 1860, at which point he sold the publishing part of his business to Edmonston & Douglas. He continued the printing activities of his firm. In 1861 he was employing 50 compositors for his printing work, a greater number than any other Edinburgh firm at that date. In 1865 his son Archibald joined the firm as a partner and the firm began publishing as T. & A. Constable Ltd. Publications Later years In the 1870s Thomas Constable devoted himself to writing. His major work was a biography of his father Archibald Constable and his Literary Correspondents (1873). He also penned some private memoirs, including Memoir of Lewis D. B. Gordon, F.R.S.E., Professor of Civil Engineering and Mechanics in the University of Glasgow (1877) and Memoir of the Rev. Charles A. Chastel de Boinville (1880). Honours In 1866 he became a Fellow of the Royal Society of Edinburgh. Personal life and death On 14 October 1837 Constable married Lucia Anna Cowan, the daughter of Alexander Cowan, a papermaker in Valleyfield, Penicuik. Their children included Archibald
