of LL.D. He was educated as a solicitor, and for many years 

 practised with mncli success at Swansea ; but in 1856 he was 

 called to the bar, and soon afterwards retired from business. He 

 then settled at Ware Priory, in Hertfordshire, at which pictu- 

 resque old mansion he resided till about four years since : thence, 

 shortly before the death of his wife, he removed to London, and 

 took a house at Kensington, where he died in consequence of an 

 apoplectic seizure on January 24, after only a few hours' illness. On 

 the previous evening he had been present at a lecture given by his 

 son-in-law, Professor ^Moseley, at the Eoyal Institution ; and he was 

 among us at the Council-table, at the Geological Club, and at the 

 Evening ^Meeting on the last occasion prior to his death. Indeed 

 his mental powers showed no signs of failure, and a slight increa- 

 sing difficulty of hearing was almost the only indication that he 

 had numbered full 76 years. 



The study of the recent !Mollusca was the chief scientific work of 

 Dr. Gwyn leffreys's life. He was one of the first to perceive the 

 importance of dredging in the British seas ; and after many years' 

 experience in private enterprise, took charge, in 1869 and 1870, of 

 the scientific work on board the ' Porcupine ' during two of her 

 cruises. Hence Dr. Gwyn Jeffteys's best scientific memorial will 

 be his writings on the MoUusca, chief of which are his large and 

 important work on British Conchology, and the papers, unfortunately 

 left unfinished at his death, on the " IMollusca of the ' Lightning ' 

 and ' Porcupine ' Expeditions," published in the ' Proceedings ' of the 

 Zoological Society ; but his exact knowledge of recent forms gave 

 his opinion an exceptional value on the fossils of the later Tertiary 

 deposits, and on these subjects he has communicated papers, more 

 valuable than numerous, to our Journal. But his other services to 

 our Society must not be forgotten. For sixteen years he was its 

 Treasurer, a position for which he was peculiarly adapted by his 

 legal knowledge and habits of business, and the duties of which he 

 fulfilled with great assiduity and invariable courtesy. He resigned 

 that office four years ago, but at the time of his sudden death was 

 still a member of the Council, having served on it continuously for 

 twenty-one years. We shall for long miss his critical acumen and 

 extensive knowledge, especially in any question relating to the later 

 life-history of the earth ; but we shall even more deeply regret the 

 cheerj-, kindly friend, and the trusty adviser, who for so many years 

 has been a familiar figure at these and many other scientific 

 gatherings. 



Alfred Tyloe was born on January 26, 1824. His parents were 

 members of the Society of Eriends, and he was educated in schools 

 connected with that body at Epping and Tottenham. At the age of 

 fifteen, however, he entered the manufactory of brass and copper 

 work belonging to his family in Warwick Lane^ This early diversion 

 from school to practical work was for llr. Tylor the beginning rather 

 than the end of his education. While singularly successful as a 

 practical man of business, not only in the above factory, but also in
