1873] Agassis? s Lectures 



Of all his varied lectures the most instructive 

 were those on glaciers. Here he spoke as an expert, 

 and every rock around was witness to his words. 

 Equally delightful, however, were the reminiscences 

 of his early life and of his fellow workers in science, 

 Schimper and Braun in Munich, Valenciennes and 

 the rest in Paris, and the three he acknowledged as 

 masters Cuvief, Humboldt, and Dollinger. "I 

 lived at Munich for three years under Dr. Dollinger's

 to him, and to him alone." 



To the Darwinian theory as it looked to him he Not a

 of animals and plants as such, but as glimpses into

 solve an attitude strikingly evidenced by the 

 fact that every one especially trained by him after-
