Dear
Sir:
I
am
sorry
that
I
have
so
long delayed
to
write
to
thank
you
for
sending
me[2]-at the
request
of
Dr.
Bucherer-a
copy
of
your
paper
on
the
principle
of
relativity.[3]
When
the
paper
came
to
me
I
was
rather
tired[4]
with
my
work.
Then
came a
holiday.
But
as soon
as
I
returned
from
the
holiday
I
fell
ill
and have
been
unwell
up
to the
present
time.
I
am now
recovering
and
hope to
be
quite
well in
a
few
days.
I
had
hoped to
make
a
careful
study
of the
paper
before
writing
to
you,
but
I
have not
been
able
to
do
so.
I have not
been
able
so
far[5]
to
gain any really
clear idea
as
to
the
principles
involved
or as
to
their
meaning[6]
and
those
to
whom
I
have
spoken
in
England
about the
subject
seem
to
have the
same
feeling.
I
think
it would
help
us
if
you were
to
write
a
short
account[7]
of the
subject
which
could be
translated
and
published
in
some English
journal,-the
Phil.
Mag. perhaps.
If
I could
give any
assistance in
the
matter
I
should be
glad
to do
so,
but
I must
say
that
I
am
not
an
expert
in
German.
I
send
a
few
papers
which I
hope you
will
accept.
They
are on
my own
lines
and
have
very
little
reference
to
the
work
of
others.[8]
This
is
mainly[9]
because
my
teaching
work
prevents[10]
me
from
reading
very
much
of
what
is
written
by
others.
I
have
been
in
Berne several
times.
My wife[11]
and I
were
there
for
one night
in
Sep.
1907.
For the
first time
I
saw
the
Alps perfectly
clear. I
thought they
looked
almost
more
beautiful
at
that
distance
than
from
Mürren
or
Grindelwald.[12]
If
I
find
myself
at
Berne
again,
I
hope
I
may
have
the
pleasure
of
meeting
you.
