Note that a - c. as here stated is an inch greater than the sum of the
smaller measures: This difference is in cement at the joints; chiefly.

a b is both in sections E and F: the space of red and white
alternative squares.
b c in F and c d in E is the course of animal ornaments
separately let in.
c d - in F is a dentil of pure white marble, worked in the
same block masonary  with the great twisted corner e f
wrought in same block with it: and e f is
10ft above balcony.
