mineral- veins, and the characters of other ore-deposits. He became 

 an Inspector of Mines in 1873, and in this position his great 

 geological knowledge and wide experience led to his advice being 

 constantly sought by the Government in connection with mining 

 questions of especial difficulty. The long series of Annual Reports 

 which he issued, as well as the contributions which he made to the 

 second Royal Commission on Coal-Supply, bear witness to his untiring 

 energy and to his extensive knowledge and his wide experience in 

 all matters connected with the art of mining. 



Not less important was his work as a teacher of the practical 

 applications of our Science. First as Lecturer to the Mining 

 School of Camborne from 1865 to 1868, and afterwards as successor 

 to our former President, Sir Warington W. Smyth, as Professor in 

 the Royal School of Mines from 1890 to the time of his death, he 

 established a foremost place in connection with mining instruction 

 in this country. Lucid as a lecturer, untiring as an author, 

 beloved alike by his students and colleagues, Le Neve Foster lost 

 his life as the result of his devotion to duty. While investigating 

 the cause of a mining disaster in the Isle of Man in 1897, he was 

 poisoned by carbonic-oxide gas, and, although his strong constitution 

 enabled him partly to recover for a time, his heart had sustained such 

 injury that he passed away somewhat suddenly on April 19th, 1904. 



Sir Clement Le Neve Foster became a Fellow of this Society in 

 1863, and in 1892 was elected to the Fellowship of the Royal 

 Society ; he Avas a Bachelor of Arts of both the Paris and London 

 Universities, and a Doctor of Science in the latter. In 1903 

 Le Neve Foster's great public services were recognized by his 

 receiving the honour of knighthood. [J. W. J.] 



Frank Rtjtley, who had been a Fellow of this Society since 

 1870, was born at Dover, the son of a medical man, on May 14th, 

 1842. His scientific training was obtained chiefly at the Royal 

 School of Mines, where he studied from 1862 to 1864. After 

 holding for a brief period a commission in the Army, he joined the 

 staff of the Geological Survey, and in 1867 he began field-work 

 with Aveline and Clifton Ward in the Lake District. Here his 

 attention was at first directed to the phenomena of glaciation, but 

 he soon turned to the study of rocks — a subject which henceforth 

 became the engrossing business of his life. Microscopic petrography, 

 though initiated in this country, was rapidly developed in Germany ; 

 and Rutley's early education at a school in Bonn led him to follow
