THE ANNIVERSARY ADDRESS OF THE PRESIDENT, 

 John Edward Marr, Sc.D., E.R.S. 



In preparing notices of Eellows of the Society whom we have lost 

 during the year, I have availed myself of the kind assistance of 

 Dr. Bather, Prof. Bonney, Prof. Judd, Mr. Linsdall Richardson, 

 Mr. Rndler, Dr. Teall, and Mr. H. B. Woodward. 



Ferdinand Andre Fouque was born at Mortain (Manche) on 

 June 21st, 1828. In 1849 he entered the Ecole Normale, and, 

 after completing his course of studies in that Institution, was 

 appointed Keeper of the Scientific Collections, a post which he held 

 from 1853 to 1858. His first piece of scientific work was done in 

 1853, in collaboration with Henri Ste. Claire Deville, and relates to 

 the chemical composition of topaz ; but it was not until the year 

 1861 that his attention was directed to those studies which have 

 made him famous. In that year he accompanied Charles Ste. Claire 

 Deville, as voluntary assistant, on a scientific expedition to 

 Vesuvius, and thus commenced the long series of researches on 

 volcanic action which terminated only with his life. 



In 1869 he became attached to the College de France, and on 

 two occasions (1873-74 and 1875-76) acted as deputy-professor, 

 once for Elie de Beaumont, and once for his old master Charles Ste. 

 Claire Deville. He succeeded to the professorship in 1877, and 

 held the post up to the time of his death. He was elected a 

 member of the Academy of Sciences on June 1st, 1881. He had 

 been a Foreign Correspondent of our Society since 1885, when in 

 1889 he was transferred to the list of Foreign Members. 



During a long and active career he took part in four scientific 

 missions, organized by the Paris Academy of Sciences for the purpose 

 of studying the phenomena of volcanoes and earthquakes. The 

 eruptions of Etna in 1865, of Santorin in 1866, and of Terceira 

 (Azores) in 1867 gave rise to three of these expeditions. The 

 fourth was for the purpose of investigating the great Andalusian 

 earthquake, which took place in 1885-86. 



The scientific work of Fouque relates almost exclusively to 

 the phenomena which are connected either directly or indirectly 

 with volcanic action. He carried out elaborate investigations into 

 the chemical nature of the volatile products, the petrographical
