Now,
to
my
great
delight,
I
can soon
put up
my
tent in
Zurich
again.[1]
No
matter
how
good my
external
circumstances have
been
here,
I
was never
able
to
get
rid
of the
feeling
that
I
am
in
a
sort
of
exile.
A
person
who
spent
his
formative
years
in
a
democratic
society
cannot
get really
used
to
a
caste
system
such
as
they
have
here. One
never
stops finding
the
snobbery
and officiousness ridiculous.
Only
since I have
been
here
have I
really
learned
to
appreciate
the
simple
and
healthy
habits and customs
of
the
Swiss. Also,
the students
do
not
show such
lively
scientific
interest
as
in
Zurich.

Prof. A.

University
Esteemed Professor Einstein:
About
a
year ago you
published
a
"Comment
on
Eötvös's
Law"
[Ann.
der.
Phys. (4)
34;
165/9
(1911)].[1]
I
would
now
like to
take the
liberty
to
draw
your
attention
to
related articles
with
which
you
are
evidently
not familiar.
An
investigation
of
the
two quotients
you considered,[2]

had
already
been
carried
out
by
P.
Walden
on
the
basis
of
experimental
material
[Ion

406
(1909)].[3]
The
expressions containing,
instead of
the
total
surface tension,
the free

tension

and
or

,
which
is
proportional[4]
to
the latter
below

the
normal
boiling
point,
have been
subjected
to
a
thorough
examination
as
to
their
validity by
P.
Waiden
[ZS.

as
well
as by
P.
Dutoit
&
P.
Mojoiu
[J.

(1909)].[6]
