“ It had been his intention to publish a comprehensive work on the mineralogy of Scotland. This he did not live to complete, but the MSS. fell into able hands, and The Mineralogy of Scotland, in 2 vols., edited by J. G. Goodchild, was issued in 1901. Heddle was one of the founders of the Mineralogical Society, and he contributed many articles on Scottish minerals, and on the geology of the northern parts of Scotland, to the Mineralogical Magazine, as well as to the Transactions of the Royal Society of Edinburgh. He died on the 19th of November 1897. ”
