part 1] ANNIVERSARY ADDRESS OF THE PRESIDENT. lxiii 



A second edition was issued in 1909. After he went to Johannes- 

 burg in 1902 he contributed several papers to the South African 

 Geological Society. In 1904 he showed that the ' older granite ' 

 was unconformably overlain by the Witwatersrand Series : he 

 claimed also that the Transvaal Coalfield was to be ascribed to the 

 Ecca Series (1904), and in a paper written with Dr. Hatch on the 

 petrography of the Rand Conglomerates, he suggested that the 

 gold had been introduced by percolating waters. Most of his time, 

 however, was probably taken up in recent years by administrative 

 duties and professional work. [J. S. F.] 



By the death, in his 90th year, of Thomas Codrington, 

 M.Inst.C.E., the Society has lost an esteemed member whose 

 Fellowship lasted nearly sixty } T ears, and whose occasional con- 

 tributions to our Proceedings and Journal cover a period of 

 nearlv fifty years. He was elected a Fellow in 1859, a year 

 remarkable in our annals as prolific in long Fellowships. His 

 association with us affords a good illustration of the benefit accruing 

 to our Science from the Fellowship of professional engineers. 

 Born at Wroughton (Wiltshire), on May 31st, 1829, Codrington 

 was educated at the College for Civil Engineers, Putney, and, after 

 serving for some years in subordinate positions, he was appointed 

 in 1874 General Superintendent for County Roads in South Wales, 

 undertaking later the supervision of the main roads in Hereford- 

 shire also. In 1882 he became an Engineering Inspector under 

 the Local Government Board, continuing in this service until his 

 retirement in 1895, after which he carried on a consultative 

 practice. He was a leading authority on the planning and upkeep 

 of roads, and on this subject he wrote ' The Maintenance of 

 Macadamized Roads' (1879 & 1892), the article ' lioads ' in 

 Encyclopaedia Britannica (1885), and ' Roman lioads of Britain' 

 (1903, 1905, 1918). He contributed his first paper to our Society 

 in 1860, on the probable Glacial Origin of some Norwegian Lakes. 

 In 1864 he recorded the discovery of Pleistocene Mammalian 

 remains near Thame ; in 1868, described a section in the Isle of 

 Wight ; and, in 1870, produced a valuable paper on the Superficial 

 Deposits of South Hampshire and the Isle of Wight. Next, after 

 a lapse of 28 } r ears, he submitted an account of some Submerged 

 Eock-Valleys in South Wales, Devon, & Cornwall (1898), in which 

 he most usefully placed on record information of geological 

 importance gathered during engineering operations, and this was
