Vol. 69.] ANNIVERSARY ADDRESS OF THE PRESIDENT. lvii 



an important monograph on bournonite ; and, after succeeding to 

 the chair at Leipzig, he accepted the responsibility of keeping 

 Naumann's well-known textbook up to date. This work has- 

 passed through fifteen editions, six of which have been edited by 

 Zirkel. 



Our late Foreign Member often visited this country, where he 

 had many personal friends, including Sorby, to whom he dedicated 

 his classic work on the ' Microscopic Structure & Composition of 

 Basalts ' (1870). 



He was a man of sympathetic nature, a delightful companion, and 

 a true friend. He took a deep personal interest in the welfare of 

 his students, and they responded with almost filial affection. He 

 received many honours from universities, scientific institutions, and 

 from the State. His colleagues showed their regard for him by 

 making him Rector of the University with which he was officially 

 connected for so many years. 



Zirkel was elected a Foreign Correspondent of the Geological 

 Society in 1869, and a Foreign Member in 1880. In 1897 he was 

 elected a Foreign Member of the Royal Society. He died at Bonn 

 on June 11th, 1912, in the 75th year of his age. [J. J. H. T.] 



By the death of Francois Alphonse Forel, who was elected a 

 Foreign Correspondent in 1910, our Society has lost a naturalist of 

 world-wide renown and one of the notable Swiss savants of the 

 last half-century. He was born at Morges on February 2nd, 1841, 

 on the shores of the lake to the investigation of which he was to 

 devote so many years of his life. 



He was educated at the Academy of Geneva, and attended the 

 medical course at Montpellier. After a lengthened stay in Paris he 

 proceeded to the University of Wiirzburg, where he took his 

 Doctorate of Medicine in 1867, afterwards remaining there as 

 prosector in the Department of Anatomy. In 1870 he returned to 

 Switzerland, and was appointed Professor of Anatomy & Physiology 

 in the University of Lausanne, a post which he held for 25 years. 

 He retired from this chair in 1895, in order that he might 

 pursue his favourite studies in various branches of natural 

 philosophy. In the preface to his famous monograph on the Lake 

 of Geneva he tells us how, at the age of thirteen, an interest in 

 natural objects was first aroused in him by his father, in connexion 

 with the investigation of the lake-dwellings of Morges, then in 

 course of excavation.
