The membranes were of a width of 27 1⁄2 inches (70 cm) and a height varying from 31 to 37 3⁄4 inches (79 to 96 cm).[11] After receiving the first and third rolls Pepys had his clerks cut the rolls up and bound in a single volume as a book, now known as Pepys 2991. The transformation of the two rolls created a horizontal page structure, and some of the ornamentation that was cut in process was copied into the volume by hand. Pepys also inserted abstracts between the two rolls and a summarizing table that was not Anthony's, but pre-dated Pepys' binding of the rolls.
