to six we have a lecture from the renowned Tiedemann. After that, I
either take a bath in the Neckar or another walk. From eight to
nine I resume my special work, and then, according to my
inclination, go to the Swiss club, or, if I am tired, to bed. I
have my evening service and talk silently with you, believing that
at that hour you also do not forget your Louis, who thinks always

Now for the first time the paths of the two brothers separated,
Auguste returning from Zurich to Neuchatel, where he entered into
business. It chanced, however, that in one of the first
acquaintances made by Louis in Heidelberg he found not only a
congenial comrade, but a friend for life, and in after years a
brother. Professor Tiedemann, by whom Agassiz had been so kindly
received, recommended him to seek the acquaintance of young
