importance
to
the intuitiveness
and
simplicity
of the mathematical
developments
than
to
the
unity
of
presentation,
hoping
that
this
would make the
paper
more stimulating.
Respectfully yours,

Highly
esteemed
Mr. E:
In
response
to
your
request,
I
am sending you by
the
same
my
"Postscript
to
the Discussion
of Kaufmann's Deflection
Measurements," together
with
the
"Discussion"
itself.[1]
But I would
like
to
add
immediately
that
Mr.
Kaufmann
subsequently
carried
out
a
calculation of
the influence
that
ions
produced
by
the
ß-rays
exert
on
the electrical
field
between
the
condenser
plates,
from which it follows
that
the
electrical
field
is
extraordinarily
close
to
being
homogeneous.
This calculation of
Kaufmann's will
appear
very
soon
in
the
Berichten der
Physikalischen
Gesellschaft.[2]
Thank
you
so
much
for
your
kind
letter and the
news,
which
were
of
great
interest
to
me.
Mr.
Laue
had also
told
me
about
his
very
pleasant
meeting
with
you.[3]
Very truly yours,
M.
Planck
65.

Highly
esteemed
Dr.
Einstein:
Some
time
from
now
I
am
to
give
a
lecture
in which I would like to discuss
your
beautiful
investigations
as
thoroughly
as
possible.
But
as
I gather
from
your paper,
"On
the
Movement of
Particles
Susp.
in
Stationary
Liquids
Required
by
the
Mol. Kin.
Theory
of Heat," A.
d.
Ph. IV
17:
551,[2]
I
still do
not
have
your
papers
on
the
foundations of
thermodynamics
(A.
d.
Ph.
9 and
11).[3]- May
I
ask
you
please
to
send
me a
reprint
of
each,
if
you
still have some?
Thanking
you
most
cordially
in
advance, yours sincerely,
Prof. Dr. Rich.
Lorenz
