years he was in their service he began those investigations into the 

 metalliferous deposits of Cornwall and Devon, which occupied 

 his mind and pen for the next fifty years of his life, and ended 

 in results which will cause his name to be ever associated with 

 those subjects. In 1828 he was elected a Fellow of the Greologi- 

 cal Society of London, and the "Murchison Medal" was pre- 

 sented to him by that society tix. months before his death ; an 

 honour that was most gratifying to him. In 1832 he held the 

 office of Assay Master and Supervisor of Tin in the Duchy of 

 Cornwall, until the office was abolished in 1838, when he retired 

 with a pension. 



In February, 1840, he was elected a Fellow of the Royal 

 Society, when he contributed a paper to their publications. 



In 1870 and 1871 he presided over our Institution, and although 

 in enfeebled health he discharged the duties which he had under- 

 taken with his former energy and ability. His address to our 

 society in 1871 was considered so important, that the Miners' 

 Association of Cornwall and Devon reprinted that portion of it 

 which related to Metalliferous deposits, and this was again trans- 

 lated into French, and published in the " Annales des Mines." 

 Another of his contributions to our Journal in 1874, on the 

 Detrital Tin-ore of Cornwall, was also published entire in 

 France, in the "Annales des Mines;" and extracts from it were 

 published separately by M. Zeiller. 



A long list of his publications is given in the volume of the 

 Bibliotheca Cornubiensis, which is already published, and is 

 therefore no doubt in the library of every Cornishman who is 

 interested in the literature and history of his county. 



Mr. Henwood had for some years been warned that his death 

 would be sudden, and a letter to one of his first patrons and 

 friends, dated November 11, 1872, expressed his feelings as being- 

 expectant of, and prepared for, such an end. 



His bust by Burnard has been presented to our Institution by 

 his executor, and will be placed with our collection of busts of . 

 scientific Cornishmen. 



Mr. Deeble Boger, of Wolsdon, is another of those whose 

 loss we have to regret, at the age of 76. Few men were better 

 acquainted with the law and rights of the Duchy of Cornwall ; 

 and he was well informed on most matters of local history. Not
