574 Obituary — Henry James Johnston-Lavis. 



August 2, 1849, he was educated at Denmark Hill Grammar School, 

 and appears to have entered at an early age into the public life of his 

 native town. He held positions on the Board of Guardians, Local 

 Eoard, Urban District Council, Hospital Board, Savings Bank, Corn 

 Exchange, Burial Board, etc., and was created County Magistrate in 

 1895. On all these positions he brought to bear his geological 

 knowledge, greatly to the advantage of his fellow-townsmen. 



Mr. Hill was a Vice-President of the Geological Society of London, 

 President of the Geologists' Association (1911-12), and h.ad done 

 a large amount of original work of value in the Cretaceous rocks. 

 But the great geological work of his life was his unselfish devotion to 

 his crippled friend Jukes-Browne. For years Hill spent week after 

 week in the field, noting and surveying county after county and 

 forwarding all the observations to his friend, who wrote them up for 

 the Geological Survey memoir called The Cretaceous Hocks of Britain. 

 Further results of this work were his brilliant addresses as President 

 of the Geologists' Association on "Flint and Chert" and " Eocks 

 containing Radiolaria", papers demanding not merely knowledge 

 but technical skill and patience. William Hill died at Hitchin, 

 November 8, 1914, and was buried there. 



HENRY JAMES JOHNSTON-LAVIS, F.G.S., Etc. 

 Born July 19, 1856. Died August 10, 1914. 



De. Johkston-Lavis was born in London, July 19, 1856. On the 

 close of his primary education at a private school he sought to enter 

 on the medical course at the University of Montpellier. That 

 institution, however, having had to be closed on account of a revolt 

 of the students, he attended instead at the University of Marseilles, 

 where he studied for a year. At the beginning of the session 1873-4 

 he transferred to University College, Gower Street, London, and also 

 studied some subjects at St. Mary's Hospital, Paddington. At the 

 former institution he was placed in the First Class in Practical 

 Chemistry in 1874, and in the First Class in Clinical Medicine in 

 1878. While there, also, he came under the teaching of Professor 

 John Morris, then at his zenith, for Geology. This subject strongly 

 attracted him and he joined the Geologists' Association in 1874, and 

 was elected a Fellow of the Geological Society in 1875, having been 

 by an oversight admitted before the full age. His first paper, ' ' On 

 the Triassic Strata which are exposed in the cliff sections near 

 Sidmouth," was read before that Society in the following year. The 

 bones he discovered at that locality proved to be new, and were 

 described at the same time by Professor H. G. Seeley under the name 

 oi Labyrinthodon Lavisii. In 1876, also, he conducted evening classes 

 in Physiology at the old Polytechnic in Regent Street. For several 

 years he made a careful study of the Lower London Tertiaries 

 exposed at Charlton and at Lewisham, which resulted in a paper 

 attempting a correlation of the two sections, read before the Geologists' 

 Association in 1877.
