Wednesday
It was very nice in Utrecht at Prof. Julius’s. He showed me his instruments and
his
theory.[4]
After that we played music with his very musical and attractive
daughters.[5]
It was an unusually fine day, perhaps the finest since I came here. To-
day is colloquium. Tomorrow I’ll be alone at Lorentz’s for the whole day. But now
I’m looking forward to home again. It’s nice that Ilse experienced such a liberation
from
penury[6]
and picked up the stitch again. We’ll be needing it. But now, don’t
be too thrifty. It’s going to be hard enough for you as it
is.[7]
It’s good that Uncle
J[acob][8]
has promised—I hope he keeps his word in the long run.
Over here I’m being nicely
spoiled[9]
(so I don’t get out of the habit). I didn’t
hold a single lecture. Freundlich published something a bit foolish again, as I gather
from information given by his colleagues
here.[10]
One can only judge once the en-
tire observational data have been mastered. He simply isn’t reliable enough, after
all. I’ll be relieved once he has his position in
Potsdam![11]
Greetings & a kiss from your

Dear Colleague,
I thank you sincerely for the effort you took to inform us of the findings of the
expeditions.[1]
The result is truly gratifying. But it is peculiar that the observed de-
viations seem to be somewhat larger than the theoretical ones. Although it only in-
volves a tenth of a second, it does look systematic. What do you think?
Cordial regards, yours,
Einstein.

Dear Papa,
How are you? I am fine, except I’m not happy that Mama’s going
away.[1]
I’m
probably going to
Aegeri.[2]
I’m not keen to leave, either, because we would have
had a little performance at school in which I would have
participated.[3]
I enjoy
playing the piano very
much.[4]
If it’s possible, send me the score: “Notebook for
little Magdalena Bach” by J. S. Bach. Mama said it would be nice for me. Many
greetings to you from your
Teddi
