The
vse
of
this
Table
following
.
IF
vpon
a
scale
or
ruler
you
diuide
one
inch
into
10
equall
parts
or
primes
,
and
againe
by
diagonal
and
paralell
lines
if
you
subdiuide
each
of
them
into
10
equal
parts
or
seconds
,
as
my
Trigonal
Scales
are
diuided
with
your
compasses
you
may
take
of
more
exact
running
measure
for
boorde
and
timber
then
by
any
other
meanes
whatsoeuer
,
and
so
place
the
same
,
or
this
Table
if
you
will
vpon
any
rule
.
Also
by
meanes
of
the
columne
of
square
roots
,
you
may
readily
finde
a
square
equal
to
any
paralelipepidon
or
péece
of
timber
which
is
thicker
then
it
is
broade
.
As
for
example
,
suppose
a
péece
of
Timber
to
be
10
inches
thicke
,
and
29
inches
broad
:
if
I
multiply
those
sides
one
by
another
,
they
will
produce
290
,
then
séekeing
in
that
columne
I
finde
289
the
néerest
number
〈◊〉
290
to
stand
against
17
:
therefore
I
say
17
inches
fere
will
make
a
square
equall
to
such
an
vnlike
squared
péece
:
then
looking
in
the
columne
of
Timber
measure
against
17
,
you
shall
finde
that
5
inches
9
primes
or
9/10
,
and
8
seconds
,
or
8/100
of
an
inch
in
length
of
that
péece
will
make
a
foote
of
Timber
.
By
the
like
meanes
you
may
finde
how
much
in
length
of
any
bredth
of
boorde
must
be
in
one
foote
.
Likewise
for
boorde
measure
,
suppose
for
example
that
a
boode
appointed
to
be
measured
is
15
inches
¾
broade
,
if
I
desire
to
know
how
much
in
length
thereof
will
make
a
foote
.
I
séeke
in
the
columnes
that
stand
vnder
the
title
of
vnites
&
parts
for
15¾
,
and
also
ouer
against
the
same
in
the
columne
vnder
the
title
of
boord
measure
,
where
I
finde
9
ynches
1
prime
or
tenth
of
an
inch
,
and
4
seconds
or
hundreths
of
an
inch
will
make
a
foote
at
that
breadth
:
the
like
may
bee
practised
for
any
other
breadth
of
boord
whatsoeuer
.
