both at Wallington, in Northumberland, and at Nettle- 

 combe, in Somersetshire. He was a Fellow of the Royal 

 Horticultural Society, which his father had founded; and 

 was also one of the Trustees of the Royal Geographical 

 Society. He did much to advance geology in the compara- 

 tive infancy of that science, and contributed many papers 

 on that subject to the " Transactions of the Wernerian 

 Society," which were characterised by much skill and ability ; 

 and the care with which they were executed is evident from 

 this consideration, that most of, if not all, the facts adduced 

 by him have been confirmed by subsequent investigators. 

 In the last paper on the rocks of Northumberland, pub- 

 lished by Messrs Topley & Lebour, the following compli- 

 mentary reference to Sir Walter occurs : " The earliest 

 paper claiming special notice regarding the intrusive nature 

 of the whin sill of Northumberland was one published by 

 Sir Walter Trevelyan in 1823, in which a careful account 

 is given of the geology of part of the northern coasts of 

 Northumberland ; a map and section accompany the paper, 

 showing how unevenly and irregularly the basalt lies among 

 the strata in that district. The limestone lying upon the 

 whinstone is described as being very crystalline towards 

 and at the point of contact." Twelve or more other papers 

 on scientific subjects issued from his pen. But, not only 

 was he ardently attached to science, he was also a lover of 

 literature. He had a refined mind, and was possessed of 

 extensive knowledge. When the Rev. Mr Hodgson was 

 writing his " History of Northumberland," he was much 

 indebted to the subject of our sketch for valuable aid, and the 

 third volume of the " Camden Society's Trevelyan Papers " 

 was edited by him conjointly with his cousin, Sir Charles 

 Trevelyan, He was of a kind and liberal disposition, and 

 hence many museums were recipients of his bounty. To 

 the New Museum in University College, Oxford, he gave 

 largely ; but his contributions also extended to the British 

 Museum, and the Museum at Kew, to which he presented his 

 Faroe Island Herbarium and other collections. Several of 

 the specimens collected in these islands were also given to 

 our museum ; and in May 1867 we have in our "Proceedings" 

 a notice to the following efi'ect: "Sir W. C. Trevelyan 

 presented a large collection of British. Continental, and
