have for study, because they are animals without legs and wings, so to
speak. There were two yoimg walruses, Hans and Heine, which went through
a number of antics at the command of the keeper. They taught them many
things and found them fairly quick to learn. On the other hand, a horse
is rather stupid. The horse is ordinarily considered to be a very clever
animal and the seal rather stupid, but, as a matter of fact, it would take
a horse five months to learn to come up and butt a man in the back when he
wanted to be fed, whereas the walrus would learn in two weeks.
I could have spent much more time at Hagenbeck's park. I found that
Mr. Zukowsky was inclined to research work. In response to any proposition
which I or Professor Bornstein made, he immediately stated that he would
be very glad to place the park at our disposal. Apparently he is a man of
wide knowledge and wide interests. He told me that they regularly sold all
their snake excrement at 25 marks ( that i3, about $6.50) per kilogram. It
was sold to some pharmaceutical manufacturing company to make drugs.
Baron von Uexkuell. I went to the aquarium and met Professor von TTex-
kuell, who is the director there. He is a man of great interests. He had
been working upon some muscular things, entirely aside from fish, naturally,
and has published some articles recently which apparently are attracting a
great deal of attention. He very kindly went out to Hagenbeck’s Park with
us, although it must have been rather hard to go on such a bad day. I
found him a most interesting man.
