Let us now treat the scroll in the same way.

First, the predication of the definition with
the definitum as subject is that when it is
permitted to scribe upon the sheet of assertion
a scroll with two graph-replicas, x and y,
in its outer and in its inner close, or on its
bottom and on it[s] patch, respectively,

then whenever it is permitted to put the
graph x upon the sheet of assertion, it will
likewise be permitted to put the graph y upon
the sheet of assertion. Or in terms of transformation
it will be permissible on the sheet of assertion
to transform x by the insertion
into it of y as a component of a compound
graph xy.
