HUGH EDWIN, the grandson of Sir George Strickland, and of the eminent Dr Edmund Cartwright, was born at Rington in the East Riding of Yorkshire, on the 2d of March 1811. He studied under Dr Arnold at Laleham, and subsequently at Oriel College, Oxford. While at Oxford his taste was directed by the teaching of Dr Buckland to the study of geology; and on his retirement to Tewkesbury he studied with great diligence and success the geology and natural history of the Cotswold Hills and of the great valley of the Severn. From numerous papers which appeared from Strickland's pen in the Transactions of the Geological Society, it appeared that he was a very industrious inquirer, an accurate observer, and a just reasoner on the geological phenomena which came under his observation. In 1835, he made a geological tour to Asia Minor, and published papers on the various topics which drew his attention during his travels. He succeeded Dr Buckland as reader in geology to the University of Oxford on the failure of that gentleman's health. In zoology he was distinguished as an ornithologist, and various contributions from Strickland appeared in the Proceedings of the Zoological Society. He likewise wrote a book on The Dodo and its Kindred in 1848, in which he concluded that this extinct bird belonged to the family of Columbidae. He was one of the original founders of the Ray Society, and he had just edited the third volume of Agassiz's Bibliographia Zoologica et Geologiae, when he was killed by a passenger-train on the Gainborough and Retford Railway, a portion of the cuttings of which he was too diligently examining, on the 14th September 1853.
