1836-38.] VISIT TO FREIBURG. 129 



near the Lake of Thun and at Oberwald, in the upper 

 part of the Valais. Guyot had added some new facts 

 (considerations) to the observations of Agassiz ; but he 

 did not write a note of what he said after Agassiz had 

 spoken. Agassiz's secretary was at the meeting ; for 

 we find in the list of persons present not belonging to 

 the society " M. Desor, geographe a Neuchatel." 



In an excursion of the society from Soleure to 

 Bienne, following the foot of the Weissenstein, and at 

 la Neuveville, Agassiz showed numerous boulders and 

 rocks polished by glaciers. De Charpentier agreed 

 entirely with Agassiz, and the majority of the fellows 

 of the Geological Society accepted the new view and 

 the glacial theory as the only possible explanation of 

 the phenomena. 



Directly after the meeting of the Geological Society 

 of France at Porrentruy, Agassiz left for Germany to 

 attend the meeting of the Association of German Natu- 

 ralists at Freiburg-im-Breisgau in the Grand Duchy of 

 Baden. During the sessions, which lasted from the 

 1 8th to the 24th of September, 1838, Agassiz had occa- 

 sion to repeat, with great force, all the arguments relat- 

 ing to glaciers, the glacial doctrine, and the existence of 

 old glaciers in the Jura, the Vosges, and the Schwarz- 

 wald. On the 25th, accompanied by Prince Charles 

 Lucien Bonaparte, and Professor and Mrs. Buckland, 

 he left Freiburg for Neuchatel. 



At Neuchatel, Agassiz had his hands more than full. 

 The lithography he had established, under the direction 

 of H. Nicolet, turned out splendid plates of fossil fishes,
