Example of quadrature by error

+++
To form the complete
figure from which one
may have greater
understanding, we shall set
down the example which follows 20 +

circular squiggle ornament

And it is from this entire square
derived by the quadrature
of errors that we may
make several inquiries,
which we could not
draw up from the first square.

---

and if you wish to derive something more
from the said square, make the same combination
of the right-hand reach in this figure as
above, by quadrangulating it as much as
is necessary to find the numbers; and
thus it may be done to infinity, as follows
hereafter.
