schists, T\'hich OYerlie the Cambrian and Silurian rocks, have been 

 thrust into their present position, in the same way as the Moine- 

 Schists have been overthrust in the Scottish Highlands. 



He further applied his thrust theor}' to the entire extent of 

 the Mountain Range, conclusions which, though not so warmly 

 welcomed on the Norwegian side of the national boundary, have 

 been widely accepted on the Swedish side. After leaving the 

 Survey he lived a very retired life, and it was a considerable 

 disappointment to many of those attending the International 

 Geological Congress in Sweden in 1910 that Prof. Tornebohm 

 was unable, from his feeble health, to take a very active part in 

 that Congress or in the field-excursions to the Highlands which he 

 loved and served so well. 



By the death of the venerable Sir Joseph Dalton Hookee, our 

 Society not only loses perhaps its oldest Fellow and one whose 

 name has, with a single exception, longest occupied a place on its- 

 roll, but there disappears from our midst the last survivor of that 

 illustrious band of our Fellows — Lyell, Darwin, and Hooker — whose 

 joint labours resulted in establishing the doctrines of Continuity 

 and Evolution upon the secure basis of observation and experi- 

 ment, thus bringing about the greatest revolution that has taken 

 place in modern times, not only in our own science, but in every 

 department of Natural History. 



Descended from the branch of an ancient Devonshire family 

 which had migrated to East Anglia, our late Fellow was born at 

 Halesworth in Suffolk on June 30th, 1817. His father was 

 William Jackson Hooker, who had already established his reputa- 

 tion as a botanist ; his mother was the eldest daughter of Dawson 

 Turner, among whose many acquirements a knowledge of botanj^ 

 was also one. When Joseph Hooker was only three years of age 

 his father was appointed Professor of Botany in the University 

 of Glasgow, and to that city the family removed, Joseph Hooker's 

 education being carried on at the High School and University. 



Charles Lyell the elder, also a botanist of some repute, who 

 resided at Kinnordy in Forfarshire, was on terms of closest 

 intimacy and friendship with Joseph Hooker's father and maternal 

 grandfather ; and thus originated, from their earliest days, that 

 close connexion between the younger members of the two families 

 which led to such important results in the history of science and 

 Avas destined to be broken only by death. It was through his
