50 PROCEEDINGS OF THE GEOLOGICAL SOCIEXr. 



stones, with belemnites, to Carboniferous strata with Coal-measure 

 plants, was not a violation of the accepted laws of stratigraphical 

 succession, but could be satisfactorily accounted for by a complete 

 inversion of the rocks. With indomitable perseverance he laboured 

 at his arduous task until at last in 1862 he was able to publish his 

 geological map of the Mont-Blanc region, followed five years later 

 by three volumes of explanatory text. He wrote also a work in 

 two volumes descriptive of the geology of the Canton of Geneva, 

 which appeared in 1880. 



One of his most important labours was the contribution made by 

 him to glacial geology in 1884, when his great map of the old 

 glaciers of the northern slopes of the Alps appeared. This work, 

 familiar to every one who has studied the glaciation of Switzerland, 

 brings graphically before the eye the size and range of the former 

 snowfields and glaciers, and the curious way in which the ice- 

 drainage differed from the present river-drainage of the same 

 region. 



On the death of Studer, Favre succeeded to the direction of the 

 Geological Survey of Switzerland, the maps of which were then 

 almost completed, the last sheet making its appearance in 1888. 

 In his later years, though enfeebled by failing health, he con- 

 tinued to interest himself in his favourite studies. Geologists will 

 remember with pleasure his experiments in illustration of the 

 plication and rupture of rocks in the process of mountain-making, 

 a]id the striking photographs by which he made them known. He 

 was elected a Poreign Correspondent of this Society in 1863 and 

 a Foreign Member in 1874 — by a curious coincidence the same two 

 years in which these honours were bestowed on Hebert. He died 

 on the 11th of July last. 



Antonio Stoppani has long been known as one of the most 

 voluminous writers among the geologists of Italy. His early 

 labours included a study of the Triassic and Infra-liassic rocks of 

 the north of Italy, and he has since continued these researches. 

 Appointed to the Professorship of Geology in the Eoyal Technical 

 Institute of Milan, he made it his duty to enlarge his acquaintance 

 with the whole range of geological formations, and to read widely 

 in his favourite science. He had considerable skill in arranging 

 and describing geological facts and speculations, as he showed by 

 producing his ' Corso di Geologia,' a work in three volumes, of which 

 the first appeared in 1871, and the others two years later. His
