4to plates, and 216 pages of text, have been published by the Palæontographical Society.
In Murchison's 'Siluria,' and Lyell's 'Manual,' Mr. Salter's services, with both pen or pencil, are apparent and acknowledged. Mr. Salter has also contributed to Sedgwick's Memoirs, 1844–47, Sharpe's Memoirs (Geol. Proceedings), and the Reports of the British Association, 1844–68 (Sections).
In the published account of the Arctic voyages of Beechey, Ommaney, and Penny, the description and correlation of the fossils was made by him. Mr. Salter has described fossils from the Himalayas, Australia, China, South Africa, Canada, Oregon, &c. &c.
A list of sixty separate papers by Mr. Salter is given in Bigsby's 'Thesaurus Siluricus,' in the preparation of which he was also engaged.
He projected and, conjointly with Mr. Henry Woodward, prepared a Tabular view of British Fossil Crustacea, showing their range in time, which was engraved and published by Mr. J. W. Lowry, in 1865, and, but for the great expense attending the engraving, several other groups were also intended to be tabulated.
In 1865, Mr. Salter received the "Wollaston Donation-fund" from the Geological Society, in recognition of his valuable services to palæontology, and especially for his Monograph on Trilobites, then in course of publication by the Palæontographical Society.
After his retirement from the office of Palæontologist to the Geological Survey in 1863, he was engaged at various times in arranging and naming the Palæozoic Invertebrata of the Manchester, Leicester, Leeds, Worcester, Malvern, Taunton, and Cambridge Museum collections; he also executed numerous plates and woodcuts. A catalogue (illustrated by himself) of the Cambrian and Silurian fossils in the Woodwardian Museum was one of the last tasks which he undertook; it remains uncompleted, as does his Monograph on the Trilobites.
It is difficult to say what combination of official conditions could have been found better suited to him than those in which he was placed. He often pictured the happiness of a post in the British Museum; but it is doubtful, had he realized his hope, whether his health would have improved. Those who knew him well will remember how cheerful and light-hearted he was at times; he was, in many ways, remarkably like a child, fond of boyish athletic sports, a lover of Nature, fond of wild flowers and domestic pet animals, which he encouraged his children to keep. Anon he would be fretful and irritable, often without any reasonable cause, proving that the chronic ill-health of which he complained was certainly mental.
His staunch friends, Murchison and Sedgwick, helped him right manfully throughout, and he had many friends in the West of England and of Scotland, who gladly welcomed him to their homes and cordially sympathized with him. But though he spoke cheerfully and hopefully after resigning his post at Jermyn Street, there is no doubt that he regretted the step he had taken.
