described a remarkable series of nine terraces which have been cut in 

 the moraines, and showed that the oldest and highest have been the 

 most inclined, indicating the tilting of the district in post- Glacial 

 times. He rejected the view of the glacial origin of this lake-basin, 

 which he explained as a greatly altered river- valle}^ According to 

 him dislocation was the chief factor in the origin of this basin, and 

 he placed ice-erosion among the secondary factors. 



From the evidence of the Lago d' Iseo district he accepted the view 

 that there have been two Alpine interglacial periods. Probably his 

 most important glacial monograph is that upon the deposits of the 

 Diluvial Aar Glacier, accompanied by a detailed map of the Glacial 

 deposits around Berne. He there again combated the view that 

 glaciers are agents of great erosion, although he admitted that they 

 might conceivably act as such if flowing at high velocity, in great 

 mass and for a prolonged time. In his later years Baltzer wrote a 

 considerable series of short papers on glacial deposits, including 

 those of Switzerland, Northern Italy, and Riigen, on the origin of 

 Alpine lake-basins, and on the tectonic structure of the Alps. In 

 1906 he issued his very useful guide to the geology of the Bernese 

 Oberland, the biggest volume in the 'Sammlung Geologischer 

 Fiihrer.' The last of his list of about 50 papers was a short note 

 in 1909 on his Lago d' Iseo monograph. 



The general impression left by a review of Baltzer's work is 

 that of an accurate, cautious investigator, whose conclusions showed 

 keen insight, whose views were fair and moderate, and who has had 

 a deep influence on Alpine Geolog} r . 



He was elected a Foreign Correspondent of this Society in 1907, 

 and a Foreign Member in 1911. [J. W. G.] 



Igijn t o Cocchi was born at Terrarossa in the Val di Magra 

 (Province of Massa) in 1828. He at first devoted himself to 

 literary studies, especially Latin literature, afterwards to chemistry, 

 anatomy, and botany, and finally to mineralogy and geology, 

 especially palaeontology and stratigraphy. 



Having graduated at the University of Pisa, he completed his 

 studies abroad, more especially in Paris and London. Later on, 

 he gave to the city of Florence his specimens, which formed the 

 nucleus of an important palaeontological collection. 



After returning to Pisa, he was for a time assistant to Savi and 

 Meneghini; he collaborated with Count A. Spa da and others in 

 the reorganization of their collections, and finally was appointed
