favourite Cullercoats, examining the pools, rocks, and weeds of 

 the littoral zone, and the fresh-drawn lines of the fishermen, who 

 every morning returned from the labours and dangers of the sea. 



He was everywhere accompanied by Miss Alder, who con- 

 stantly attended to his simple wants and comforts, assisted him 

 in his studies, and was, in short, essential to his life and health. 



Thus it was that, by undivided devotion for many years to 

 the systematic observation and collection of the different animals, 

 in their natural resorts, and by careful study and arrangement 

 of them at home, he was enabled slowly but surely to develope 

 and mature his talents, and to amass the large Museum of British 

 Shells and Zoophytes which was his pride, and one of the chief 

 foundations of his fame as a naturalist. 



He was one of the founders of the Natural History Society 

 of Northumberland and Durham in the year 1839, and took a 

 lively and active interest in the formation of its valuable Museum, 

 the first honorary curators of which were Messrs. John Adamson, 

 G. Gibsone, J. H. Fryer, and Joshua Alder. He gave important 

 aid in naming and arranging the fossils ; to the Conchological 

 department he largely contributed by gifts, and with Mr. J. H. 

 Fryer completed its arrangement. The beautiful collection of 

 Corals, and other Zoophytes, presented to the Society by the 

 Right Honourable the Earl of Tankerville, was also arranged 

 by Mr. Fryer and Mr. Alder. 



To the Transactions of the Natural History Society he con- 

 tributed, in 1830, "A Catalogue of the Land and Fresh Water 

 Testaceous Mollusca found in the Yicinity of Newcastle-upon- 

 Tyne, with Remarks."* This, the most extensive local British 

 Catalogue at that time published, contained seventy-one species, 

 forty-five of land, and twenty-six of fresh- water species. For 

 three or four years previous to the above date he had been zeal- 

 ously exploring the environs of his native town, and other parts, 

 in company with Messrs. Albany Hancock and John Thornhill, 

 and a perusal of the remarks at the end of the Catalogue shows 

 that at that time he had accustomed himself to those minute 

 and accurate observations which, in after years, rendered him so
