We may here draw a corollary analogous
to, but much more obvious. Namely, [To?] say
that it is permissible to scribe any graph,
y, on the sheet of assertion is to say that, it is
permissible to transform a replica of the blank
into a replica of y. But this, according to this
part of the definition of the scroll, permits us
to place on the sheet of assertion the scroll

Hence we have

Permission No 4. If a graph could be
permissively scribed on the sheet of assertion a
double enclosure containing that graph may
be placed on the sheet of assertion.
