particularly friendly and obliging to us.

In the afternoon from two to three I attend Geiger's lectures on
pharmaceutical chemistry, and from five to six those of Tiedemann
on comparative anatomy. In the interval, I sometimes go with this
naturalist, so recently arrived among us (his name is Agassiz, and
he is from Orbe), on a hunt after animals and plants. Not only do
we collect and learn to observe all manner of things, but we have
also an opportunity of exchanging our views on scientific matters
in general. I learn a great deal from him, for he is much more at
home in zoology than I am. He is familiar with almost all the known
mammalia, recognizes the birds from far off by their song, and can
give a name to every fish in the water. In the morning we often
stroll together through the fish market, where he explains to me
all the different species. He is going to teach me how to stuff
fishes, and then we intend to make a collection of all the native
kinds. Many other useful things he knows; speaks German and French
equally well, English and Italian fairly, so that I have already
appointed him to be my interpreter on some future vacation trip to
Italy. He is well acquainted with ancient languages also, and
studies medicine besides. . .

A few lines from Braun to his mother, several weeks later, show
that this first enthusiasm, poured out with half-laughing
extravagance to his father, was ripening into friendship of a more
serious character.

BRAUN TO HIS MOTHER.
