(With a portrait of its President, Sir Archibald Geikie, D.C.L., Sc.D., Sec. R.S.) ? 
E are glad to be able to present our readers with a portrait of 
Sir Archibald Geikie, F.R.S.,? the distinguished President of 
the Geological Society of London, who, on account of his very large 
and important contributions to our science, was last year unanimously 
elected a second time President of the Society in anticipation of its 
centenary, which will take place on November 13th, 1907, he having 
been deemed the most fit and proper Fellow to represent the Society 
as its chief officer upon so important and memorable an occasion in 
its history.° 
In the earlier years of his geological career Sir A. Geikie spent the 
major part of his time in the Highlands and Lowlands, amid the glens, 
lochs, and mountains of his native Scotland, and although in 
Murchison’s and Ramsay’s days he passed many of his winters in 
London engaged on Survey work at Jermyn Street, it was not until 
he was appointed Director-General of the Geological Survey of the 
United Kingdom and Director of the Museum of Practical Geology in 
1882, offices which he held until 1901, that he became an habitué of 
the Geological Society and a constant figure at its meetings. 
In those days (from 1855) when as a youthful geologist of 20 
he commenced his official work, and afterwards (1867-82) when 
1 For permission to use the present portrait we are indebted to the President and 
Council of the Royal Scottish Geographical Society, Edinburgh, in whose journal it 
first appeared. 
2 For a brief sketch of the life of Sir A. Geikie see Grou. Mac., 1890, pp. 49-51, 
with a portrait ; see also ‘‘ Who’s Who,” 1907. 
3 There have been forty-three Presidents in 100 years (six of whom have been 
once re-elected and one twice re-elected); G. B. Greenough having served three 
times (1807-18, 1818-20, 1833-5); and the following twice: Buckland (1824-6, 
1839-41) ; Murchison (1831-8, 1841-3) ; Sir C. Lyell (1835-7, 1849-51) ; Leonard 
Horner (1845-7, 1860-2); W. J. Hamilton (1854-6, 1864-6); and Sir A. Geikie 
(1890-2, 1906-8).
