Ixxvi PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [April 1914, 



At the time of his retirement from the Geological Survey he 

 had reached the age of 60, and the first symptoms of his illness 

 had appeared. He lived five years more, working with indomitable 

 fortitude hut with gradually decreasing strength, until the end 

 came on February 6th, 1914. 



Tempest Axdersox, M.D., Hon. D.Sc. (Leeds), J.P., was a 

 member of a well-known Yorkshire family, and showed a keen 

 interest in fostering the study of science in his native county. 

 Born in 1846 he was educated at St. Peter's School, York, and had 

 a distinguished career at University College, London, and at the 

 University of London. In his profession he devoted his attention 

 particularly to diseases of the eye, on which he published several 

 papers, and was for some years Consulting Ophthalmic Surgeon to 

 the York County Hospital. In his spare time he proved himself 

 to be a capable mountaineer and travelled widely, always with the 

 view of adding to his collection of photographs of places of interest. 

 But his reputation as a man of science was due more especially to 

 his photographic studies of the phenomena attendant upon volcanic 

 eruptions and the flow of lavas. As a result of long experience in 

 using the camera under difficulties, and often at great personal risk, 

 he had brought his apparatus to a high degree of perfection, and by 

 his geological knowledge had been able to select subjects, not merely 

 of sensational interest, but of utility to students of ancient and 

 modern volcanoes. His photographs were frequently exhibited at 

 scientific meetings. 



In 1902 Anderson was commissioned by the Royal Society to 

 undertake a joint investigation with Dr. J. S. Flett on the eruption 

 of the Soufriere in St. Vincent. The report, illustrated by remark- 

 able photographs by Anderson, appeared in the Philosophical Trans- 

 actions for 1903, and was followed in 1908 by a second report, in 

 which Anderson described the changes that had been more or less 

 permanently effected by the outburst and by subsequent erosion of 

 the ejected material, as observed by him in 1907. In 1903 he 

 published his well-known work on ' Volcanic Studies in Many 

 Lands.' The material for this work had been gathered by exami- 

 nation of Skapta Jokull in Iceland, by more than one journey to the 

 Lipari Islands, and by visits to New Zealand, Kilauea, Mexico, 

 Guatemala, and Savaii. 



Tempest Anderson was a valued member of several scientific 

 societies. As President of the Yorkshire Philosophical Society he
