additively. Many
ideas occurred to
me as well,
but
I
always
had
to
drop my
head
in
resignation
again.[11]
The Lord did
not
make it
easy
for us!
I
also have heard
about the
American measurements and discussed
them
with
Freundlich.[12]
They
do not
seem
to
prove anything yet.
No flawless
measure-
ments have been carried
out
yet on
terrestrially
generated
lines;
the
electrical
arc
used
up
to
now
is
unsuitable.
We
are now
in
the
process
of
procuring
or begging
for
the
funds for
an
electrical furnace
that
generates
flawless
lines
thermally. Only
in
this
way
will
secure
results be
attainable.
In
a
few
years
the
verdict
will
be
in.[13]
You
probably
know
that
I
received
a
call
to
Zurich
on
the
instigation
of
my
friend
Zangger.
After
agonizing
vacillation,
I declined.[14] I
am so
much indebted
to
my colleagues
here
that
it
would
not
have been
right
to
go
away,
as
fond
as
I
am
of
my
Zurich.
Now
that
you
write
me
that
you
are staying
in
Zurich,
I find
that it
would be
completely superfluous
for
me
to
go
there
as
well. I
am even
more
sorry
though
that
it is not
free will
but
a concern
for
your
health that
forces
you
to stay
in
Zurich.[15]
For
Zurich,
on
the other
hand,
I
am glad
that
you are
not
going
away.
Young people
can
learn
a
great
deal from
you,
not
from
me,
since I
personally
am
incapable
of
anything.
I
am one
of those who
ponders
a
lot
but
has
learned
nothing.
I
suggested
that
I
come
to
Zurich twice
each
year
for
a
month
in order
to
hold lectures there.
Now
that
you
are
continuing
to
teach
there,
my proposal
seems
ridiculous
to
me;
I
am
going
to write to
Zangger
in
this
vein
as
well.[16]
Now
that the
semester has
started,[17]
I
cannot
easily
come
to
Switzerland.
However,
if
my
always
somewhat
unstable health
allows
me,
I shall
go
there
at
the
beginning
of
February
for at least four
weeks;
I
am very
much
looking
forward
to
being
able
to
speak
with
you.
Cordial
regards, yours,
Einstein.

Argelander
Street, 27 September 1918
Highly
esteemed
Colleague,
Your second
engaging
letter
amused
me
very
much
as
well.[1] Many
thanks
for
it,
likewise for
kindly mailing
me
your
little
book,
which
I
read
immediately.[2]
I
knew most of
it
already,
but
still must
study
it
more
thoroughly
later,
of
course.
But
why
did
you
fear
offending
me?
Any
decent
author
is
surely glad
for
rea-
sonable
criticism,
from which he
can
learn. And such
a
very
kindhearted
one as
yours,
at
that.
I
possibly
did not deserve it at
all,
since
I
myself
have sometimes
