MONT BLANC AXD THE MER DE GLACE. 19 



Mount Auburn, a rude but eloquent monument, in its ex- 

 ternals as unlike the imposing sculptures which surround 

 it as in the interest it awakens more touching, more 

 inspiring and more catholic. On one side is engraved: 



JEAN Louis RUDOLPIIE AGASSIZ. 

 On the other: 



BORN AT MOTIER, SWITZERLAND, MAY 28, 1807. 

 DIED AT CAMBRIDGE, MASS., DECEMBER 14, 1873. 

 And on the edge: 



Boulder from the Aar Glacier.* 



Winding through the gorges, often vineyard-fringed on 

 either hand, we come out at length into the broad valley 

 of Switzerland, resting between the Jura and the Bernese 

 Alps. The Alpward glimpses and nearer landscapes be- 



* In according to Agassiz the great credit of placing the " Glacier Theory " 

 on a firm foundation, we must not overlook the work of his predecessors. In 

 1815 Playfair attributed to glaciers the transportation of erratic blocks. In 1821 

 M. Venetz advanced the opinion that the glaciers of Valais and adjacent regions 

 had formerly a vastly greater development than at present (Venetz, Mimoire sur 

 la temperature dans lea Alpes, 1821, in Memoires de la socicte' helvetiquc dcs sci- 

 ences naturelles, vol. i, pt. ->). >I. Venet/, does not in this memoir attempt to 

 explain by the same means the general phenomena of the boulder formation, but 

 it is reported that some years later he gave this extension to his views. In 1829 

 Goethe clearly shadowed forth the same theory iu Wilhelm Jldster's Wander- 

 ja/tre, vol. ii, ch. 10. In l&M M. Jean de Charpentier, in a memoir read before the 

 " Helvetic Society of Natural Sciences,'' at Lucerne, on the probable cause of the 

 transport of erratic blocks in the valley of the Rhone (See Anti-ales des Mines, 

 viii; also in German, in Froebel and Ileer's Mittheilunrjcn aus dem Gebiett df.r 

 tlieoretischen Krdkntide,\t 482 $eq.), presented substantially the modern theory of 

 glacier transportation. This paper was the occasion which directed the attention 

 of Agassiz to the same investigation, and hence, in 1836, he spent some months 

 in Charpcntier's vicinity for the purpose of making observations for himself 

 (Charpentier, Basal, p. 1). 



In 1837 M. Agassiz. as president of the same society, delivered at Neuchatel 

 an opening discourse on this subject. It gave rise to a discussion which occupied 

 a large part of the time of the session. 



In 1840 appeared Agassiz' great work. Etudes fur les Glaciers, with an atlas 

 of thirty-two plates. In the same year appeared works by others Godeffroy, 

 Notice ft'ir les Glaciers, les moraine* e( lea Blocs erratiques des Alpes, Paris and 

 Geneva; Le Chanoinc Rendu. Tlit-orif de* Glaciers dc la Savoie. Chambery. M. 

 Jean de Charpentier's E**ai anr les Glaciers was then written, but it seems not 

 to have been published till 1841.
