RICHARD HILL TIDDEMAN, M.A. (Oxon.), F.G.S., etc. 



Born February 11, 1842. Died February 20, 1917. 



We have to record the loss of Mr. Richard Hill Tiddeman, M.A., 

 F.G.S., who from 1864 to 1902, for thirty-eight years, held the post 

 of Geologist on the Geological Survey of England and Wales, during 

 which time he served under four successive Directors : Murchison, 

 Ramsay, Geikie, and Teall. 



His principal work was in connexion with the Carboniferous Rocks 

 of Yorkshire and the neighbouring counties of Cumberland and 

 Lancashire, on which he was occupied for about twenty years. Later 

 he did good work in North Wales. He was recognized as one of the 

 leading authorities on these deposits and his knowledge was always 

 willingly imparted to other workers, to whom he was an ideal 

 companion and guide. In appreciation of his services the Yorkshire 

 Geological Society elected him their President in 1914, and during 

 his term of office he was a most valuable guide and instructor in the 

 field and at the Society's meetings. 



In presenting the Murchison Medal to Mr. Tiddeman in 1911, 

 Professor Watts, the President of the Geological Society, said: 

 " Ever since the beginning of Mr. Tiddeman's workfor the Geological 

 Survey on the borders of Yorkshire and Lancashire he has kept his 

 eyes open to the observation of exceptional facts, and his mind 

 employed in working out explanations for them. The excavation of 

 the Victoria Cave, Settle, in which he took so active a part gave us 

 valuable information on the historr of the Pleistocene Mammalia ; 

 his work on the elaciation of North Lancashire still remains ' a model
