Causes
of
Want
of
Accuracy.
The
use
of
an
elastic
fruit
in
early
experiments
leads
to
a
want
of
accuracy
in
the
first,
steps
of
the
operation,
which
causes
very
annoying
difficulties
afterwards;
and
therefore
a
solid,
inelastic
body--an
egg
boiled
hard--is
recommended
as
the
first
object
to
be
imitated.

Making
the
Moulds--First
Half.
Having
filled
a
small
pudding
basin
about
three-quarters
full
of
damp
sand
(the
finer
the
better),
lay
the
egg
lengthways
in
the
sand,
so
that
half
of
it
is
above,
and
half
below,
the
level
of
the
sand,
which
should
be
perfectly
smooth
around
it.
Then
prepare
the
plaster
in
another
basin,
which
should
be
half
full
of
water.
Sprinkle
the
plaster
in
quickly
till
it
comes
to
the
top
of
the
water,
and
then,
having
stirred
it
for
a
moment
with
a
spoon,
pour
the
whole
upon
the
egg
in
the
other
basin.

Making
the
Moulds--Second
Half.
While
the
half
mould
thus
made
is
hardening
thoroughly,
carefully
remove
every
particle
of
plaster
from
the
basin
in
which
it
was
mixed,
and
also
from
the
spoon
which
has
been
used.
This
must
be
done
by
placing
them
both
in
water
and
wiping
them
perfectly
clean.
This
is
highly
important,
since
a
small
quantity
of
plaster
which
has
set
will
destroy
the
quality
of
a
second
mixing
if
it
is
incorporated
therewith.
In
about
five
minutes
the
half
mould
will
be
fit
to
remove,
which
may
be
done
by
turning
the
basin
up
with
the
right
hand
(taking
care
not
to
lose
the
sand),
so
that
the
mould
falls
into
the
left
hand.
