the glaciers and their attendant phenomena, which had so captivated his imagination, were ever present to his thought. In August of the year 1838, a year after he had announced at the meeting of the Helvetic Society his comprehensive theory respecting the action of ice over the whole northern hemisphere, he made two important excursions in the Alps. The first was to the valley of Hassli, the second to the glaciers of Mont Blanc. In both he was accompanied by his scientific collaborator, M. Desor, whose intrepidity and ardor hardly fell short of his own; by Mr. Dinkel as artist, and by one or two students and friends. These excursions were a kind of prelude to his more prolonged sojourns on the Alps, and to the series of observations carried on by him and his companions, which attracted so much attention in later years. But though Agassiz carried with him, on these first explorations, only the simplest means of investigation and experiment, they were no amateur excursions. On th

, the flora of the glaciers and the surrounding rocks; to M. Desor, the glacial phenomena proper, including those of the morrly days of March, 1841, Agassiz visited, in company with M. Desor, the glacier of the Aar and that of Rosenlaui. He wishedar accumulated. In addition to his usual collaborators, M. Desor and M. Vogt, he had, therefore, invited as his guest, dur Jungfrau. The party consisted of twelve persons: Agassiz, Desor, Forbes, Heath, and two travelers who had begged to join th reflected color. The effect is admirably described by M. Desor in his account of this excursion, Sejours dans les Glacie, Sometimes Moril, but I have retained the spelling of M. Desor.—E. C. A. where they expected to sleep.

nd there reaching the sea-coast, we have unchanged glacial drift deposit. At some points the alteration is so slight as to denote only a momentary rise of the sea. Under these circumstances one would naturally look for fossils in the drift, and M. Desor, in company with M. de Pourtales, was the first to find them, at Brooklyn, in Long Island, which lies to the south of New York. They were imbedded in a glacial clay deposit, having all the ordinary character of such deposits, with only slight trs of divers forms and dimensions. At East Boston you cannot see what underlies this deposit; but no doubt it rests upon a rounded mass of granite, polished and grooved like several others in Boston harbor. . . . In our journey to Niagara, Mr. Desor and I assured ourselves that the river deposits, in which, among other things, the mastodon is found with the fresh-water shells of Goat Island, are posterior to the drift. It is a fact worth consideration that the mastodons found in Europe ar
