lii PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [JuUG I9I2, 



Gregoeio STErANESCTT, who was elected a Foreign Correspondent 

 of this Society in 1899, had occupied for many years the Chair of 

 Oeology in the University of Bucarest. He may be said to have 

 initiated the official Geological Survej' of Eumania, a department 

 wluch has of recent years greatly extended its activities. He 

 <lescribed the fossil Dinotheria discovered in his native country, 

 and being enthusiastically desirous of spreading the knowledge 

 of the science among his countrymen, he published in 1S90 an 

 elementary text-book of geology in the Eumanian language. 



The great merit of the work of Prof. Alfred Elis Toexebohm 

 was recognized by the Geological Society, in his election as a 

 Foreign Correspondent in 1910, but he unfortunately died on 

 April 21st, 1911, in his 73rd year, before being elected a Foreign 

 Member. He was born on October 16th, 1838. At the Tekniska 

 Hiigskola of Stockholm he devoted himself to Chemistry and 

 Physics, and so laid the foundation for his future career. He 

 joined the Geological Survey of Sweden in 1859, and between 

 that date and 1873 he published several maps, chiefly delineating 

 Archaean, Cambrian, and Silurian rocks, which in places appeared 

 to be conformably overlain by mica-schists, gneisses, etc., in a 

 manner not unlike the similar rocks in the jS'orth-West Highlands. 

 Leaving the Survey in 1873, he travelled in Central Europe, and 

 «pent some time in studying Avith Zirkel at Leipzig. A year or 

 two after his return he was appointed Professor of Mineralogy 

 and Geology at the Tekniska Hiigskola at Stockholm, and he 

 •continued to hold that office till appointed in 1897 Director of the 

 Swedish Geological Survey, a post which he resigned in 1907. 

 During this time he published petrographical papers and made 

 an exhaustive study of Portland cement, working at the subject 

 •on petrographical lines. Other economic work accomplished by 

 him had relation to several of the great fields of iron- and copper- 

 ore, like those of Dannemora, Taberg, Atvideberg-Bersbo, and 

 Pitkaranta. He published also a map of Central Sweden, a memoir 

 on the outlines of the geology of Central Scandinavia, and a wall- 

 map of I^orthern Europe. 



Growing dissatisfied with the I'esults of his earlier survey of the 

 Highlands of Scandinavia, he spent many years between 1868 and 

 1888 in re-traversing his old ground in all directions, working 

 xery hard, and enduring no small privations. At the end of his 

 investigation he had arrived at the conclusion that the gneisses and
