 allows, represented with their peculiarities in the relief. 



For further illustrations we can consult the geolo- 

 gical wall profile, the maps and photographs from 

 nature in the exhibition rooms. 



This relief, looked at through a telescope, and 

 from a distance, has an extraordinary plastic effect.

1) Collection of 276 specimens of stones from the 

 Swiss Alps, classified and grouped by Dr. C. Schmidt, 

 professor of geology at the Basle university. 



This collection is a capital illustration of the petro- 

 graphic composition of the Swiss Alps. Sediment-stones, 

 eruptive stones, and old crystalline slate, as well as 

 metamorphised sediments have here found their proper 

 appreciation. 



The arrangement of the stones is very nearly that 

 of the legend of the geological and synoptical table of 

 Switzerland 1 : 500,000 (1894) by A. Heim and C. 

 Schmidt, and is consequently strictly geological. 



2) Collection of stones from the Mont- Blanc group 

 in 80 specimens, according to the statement of Dr. L. 

 Duparc, professor at the university of Geneva (author 

 of a standard-work on Mont-Blanc); they were collected 

 on the spot, and proved authentic in collaboration with 

 Dr. Pearce. 



(In the present collection are assembled all the most 

 important types of stones, eruptive stones as well as 

 sedimentary and cristalline stones and these give a 

 perfect image of the metamorphosis accomplished by the 

 pressure of the granite in the upper layers). 



The place where each sort of stone has been found 

 is indicated, with its number, in the geological map of 

 the Mont-Blanc group (see Map on the eastern wall). 



3) Collection of stones from the Gotthard Tunnel 

 (18721881). 



4) Collection of stones from the Simplon Tunnel 

 (1898-1905).

 in Geneva. These sections, laid normally in the direction
