Obituary— Mr. J. W. Salter. 479 



During his period of office Mr. Salter prepared three Decades, with 

 10 plates each (8vo. size), on the Trilobites in the collection at 

 Jermyn Street, and, in conjunction with Prof. Huxley, a Monograph 

 on the genus Pterygotus, illustrated with sixteen folio plates. He 

 also completed a Decade on the Echini, commenced by Prof. Forbes ; 

 and supplied a part of the palaeontology to Prof. Phillip's Memoir on 

 Malvern. 



The Paleeontological portion of Prof. Eamsay's Memoir on North 

 Wales was also written by Mr. Salter. 



One result of the combination of the " Greological Survey of the 

 United Kingdom" with the " Museum of Practical Geology" and the 

 " Eoyal School of Mines," has been not only to require from the 

 officer holding the position of Paleontologist a large amount of 

 routine work in examining and naming specimens and preparing 

 lists of fossils of most prodigious length in connexion with the Survey, 

 but the duties of a Curator in arranging and naming the fossils ex- 

 hibited in the Museum, and, added to all this, a series of demonstra- 

 tions have to be given annually to the pupils of the School of Mines, 

 on fossils characteristic of the various strata, with their range and 

 distribution in time and space. 



More than thirty papers by Mr. Salter, on various geological 

 topics, are to be found in the Journal of the Geological Society ; he 

 also wrote in the " Annals and Magazine of Natural History," the 

 Geological Magazine, &c. 



Four parts of a Memoir on British Trilobites, illustrated by thirty 

 4to. plates, and 216 pages of text, have been published by the 

 Palseontographical 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: to 1847 ; 

 Sharpe's Memoirs (Geol. Pioceedings) ; Eeports of the British 

 Association, 1844-1868 (Sections). 



In the published account of the Arctic voyages of Beechey, Om- 

 maney, 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, etc., etc. 



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, pre- 

 pared a Tabular view of British Fossil Crustacea, showing theii- 

 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 PalEeontology, and especially for his Monograph on Trilobites, 

 then in course of publication by the Pala3ontographical Society. 



After his retirement from the office of PahBontologist to the 

 Geological Survey in 1863, he was engaged at vai'ious times iu 

 arranging and naming the Palaeozoic Invertebrata of the Manchester,
