DIOR AT. 
Art the close of the recent International Congress of Geolo- 
gists in Switzerland an elaborate excursion was organized, as is 
well known, under the leadership of Dr. Albrecht Penck, of the 
University of Vienna, Dr. Eduard Bruckner, of the University of 
Berne, and Dr. Léon Du Pasquier, of Neuchatel, the purpose of 
which was to inspect the most instructive sections of the glacial 
system of the Alps. The appointments are reported to have 
been most admirable and carried into execution with rare suc- 
cess. Very unusual opportunities were afforded for examining 
representative deposits and for comparisons of phenomena on 
both sides of the Alps. At the close a letter very significant of 
the impressions formed was addressed by the twenty-nine mem- 
bers of the party then present to Dr. James Geikie, reciting that 
as members of the Glacialists’ Excursion they had studied the 
superposition of three successive glaciations and their inter- 
glacial deposits on both sides of the Alps, and desired to 
address their congratulations to the author of The Great [ce Age 
and to express their regret that he was unable to be one of 
their party and see for himself a series of exposures which would 
have had a very special interest for him. The signers embraced 
Albrecht Penck, Eduard Briickner, André Delebecque, Léon Du 
Pasquier, Hugh Robert Mill, London; Andr. M. Hansen, Chris- 
tiania; K. Keilhack, Berlin; E. Zimmerman, Berlin; A. Jentsch,
