Perimeter survey with a column-total of 5698
Two columns of measured lengths summed, with perimeter schemas
The left margin holds a double column of numbers that are added down to a total of 5698, gathering the measured lengths of the survey opposite. The rest of the sheet carries perimeter schemas - one read from top to bottom, two short stretches at the upper right, and a further schema meant to be read by turning the page counter-clockwise - each side labelled with a fraction, a unit (lib, po, sc, me) and a figure. The page continues the measured survey of the neighbouring folios. It is numerical throughout, with no continuous prose.

Two columns of lengths summed to 5698
The left margin carries a double column of figures - pairs such as 60/142, 196/34, 160/200 - added down to a total of 5698 written at the foot. The column gathers and totals the measured lengths drawn on the facing survey.
Perimeter schema read from top to bottom
A perimeter schema runs from left to right and from top to bottom, its sides labelled with lengths (4th lib 130, 1/2 lib 127, 3/4 lib 115) in the same fractional units as the neighbouring folios.
A perimeter read by turning the sheet counter-clockwise
A further perimeter schema is lettered so that its figures fall into place only when the page is rotated counter-clockwise - 3/4 me 32, 30 po, 24 ma, 110 1/4 po, 1/2 sc 100. The units (po, li, sc, me) match the fractional measures used across the opening.
