334 THE JOURNAL OF GEOLOGY. 



Schmidt will conduct a party over the central Alps from Zurich 

 to Lugano, visiting the " cliffs" of the Mythen and following the 

 Gothard route across the crystalline axis of the Alps. Professor 

 Baltzer, of Bern, will conduct another party over the Bernese 

 Alps, from Lucerne to Tessin, examining the intricately plicated 

 strata of the Gstellihorn, passing over the Grimsel and visiting 

 the glaciers of the Unteraar and the Rhone. Professor Schardt 

 will lead a party over the western Swiss Alps from Bulle, study- 

 ing the complicated structure of the Alps of Freiburg, and cross- 

 ing the Tete-Noire to Domo-d' Ossola. These excursions will 

 furnish foreign geologists the best possible opportunity of 

 becoming acquainted with the complex structure and widespread 

 metamorphism which have become classic through the untiring 

 energy and intelligent investigation of the Swiss Geologists. It 

 goes without saying that all who can find the time and means at 

 their command will avail themselves of these exceptional oppor- 

 tunities, and that the Sixth International Congress of Geologists 

 will surpass its predecessors both in the number of members 

 attending and in the benefits derived from the meeting.
