 The Hotel des Neuchatelois.-A great rock standing in the middle of the Ar glacier, in the the Alps of Switzerland, formed the principal part of the Hotel des Neaehatelois, a rough shelter used by Agassii and his friends while investi- gating the phenomena of glaciers from 1890 to IS43. Frost has since split the rock into a thousand pieces, three of which have just been identified hy Mons. Forel. From the record ot the hotels original position Jeff by Agassiz, and che made by Forel, is appears
