and is developing much understanding and love for this enterprise; he’s making
very rapid progress and seems to be much more musical than one would have
thought earlier.
Albert[7]
is very skillful and is always building something. Now he
even earned a few francs through the sale of a little model of his own making.
With amicable greetings,
Miza.

Dear Else,
This stay is extraordinarily charming. Tomorrow we’re driving out to see De
Haas, who is
ill.[1] Ehrenfest[2]
is a very conscientious impresario; he’s keeping ev-
eryone off my back this time. I play music, talk shop, and converse with him about
all sorts of things. He is an incomparably inspiring person. Today at the colloquium
he delivered a talk that was simply masterful. The plates of the expeditions have
now been measured (definitively). My theory has been verified exactly with the
greatest precision conceivable. Eddington reported it
here.[3]
Now no rational per-
son can doubt the validity of my theory anymore. This evening two letters of yours
arrived at once. I didn’t send you a telegram upon arrival because it was already ter-
ribly late and I was lucky enough to get a room through the help of a Dutch fellow
passenger. Planck is also going to Rostock; he wrote me
here.[4]
Many thanks to
Ilse for the message; I will send
condolences.[5]
Warm greetings & kisses from your
Albert.

Dear Else,
One week is almost over already, a really wonderful and harmonious
time.[1]
And the glorious, rare weather of brilliant sunshine here! Yesterday I was with
Ehrenfest in Delft, where we visited de Haas, who unfortunately fell quite disturb-
ingly ill (tenacious bronchitis, had already been tubercular
once).[2]
There I also
saw Lorentz’s magnificent daughter
again[3]
—these Lorentzians are superhumans
in the noblest sense. Then we wandered about in Delft—a very picturesque city.
