470 SUBALPINE PLIOCENE CONGLOMERATES. [ Aug. 1902, 
Deckenschotter, as to which some of the speakers enquired, the 
Author observes that the more recent writers on ‘ Cavernous 
Nagelfluh,’ as it is locally called, are the late Dr. Wettstein,’ 
Prof. Mihlberg,” the late Dr. L. Du Pasquier,? and Dr. Appli.* The 
first of these regarded the Uetli deposits, and generally all the 
compact or loose conglomerates of the Zurich district which exhibit 
cementation, as Glacial, but without reference to a Pliocene glaciation. 
Prof. Mihlberg’s investigations bear exclusively on the gravels of 
the Canton of Aargau, and, with a leaning to the latest views of 
Prof. Penck and Prof. Briickner, he assumes five glaciations. The 
late Dr. Du Pasquier examined more especially the alluvia of the 
Aare and Rhine Valleys between Aarau and Bale, dividing them 
into Deckenschotter, Upper- and Lower-Terrace Gravels in relation 
to the three glaciations; and Dr. Appli adopts the same division 
for the gravel-deposits of the Limmat Valley and round the Lake 
of Zurich. Thus each of these writers confines himself, in the main, 
to a separate, more or less prescribed local area. So far as the Author 
is aware, his paper is the first attempt to deal comprehensively with 
the subject, by drawing conclusions from an examination of the 
whole Subalpine region extending from the base of the Alps to the 
Rhine near Bale, and the same applies to the Rhone Valley from 
Lausanne & Bellegarde and Lyons.— May 31st, 1902. |
