work was unfortunately delayed for nearly five years, owing to a dispute and a law process with the engraver, and the delay deprived Dalyell of the full credit of several of his discoveries in connection with medusae. The first volume of his last and great work, The Powers of the Creator displayed in the Creation, or Observations on Life amidst the various forms of the humbler Tribes of Animated Nature, was published in 1851. The second volume, after the author's death, was brought out in 1853, under the superintendence of his sister, Miss Elizabeth Dalyell, and Professor John Fleming, D.D., while the third volume was delayed until 1858. Dalyell became an enrolled member of the Highland and Agricultural Society of Scotland in 1807, and in 1817 was presented by his fellow members with a piece of plate for the invention of "a self-regulating calendar". He was one of the original promoters of the Zoological Gardens of Edinburgh and 'preses' of the board of directors in 1841. He died at 14 Great King Street, Edinburgh, 7 June 1851, and was buried beside his ancestors in Abercorn Church. He was never married, and his successor in the baronetcy was his brother, Sir William Cunningham Cavendish Dalyell. Works Besides the publications already mentioned Sir John Dalyell was the author, editor, or translator of the following works; Fragments of Scottish History, Constable, Edinburgh (1798) Tracts on the Nature of Animals and Vegetables, by L. Spallanzani, a translation, 1799, and another translation of the same work in 1803.
