A sequence of thirteen numbered geometric figures
Column of numbered triangles beside a larger sheet of radiating-line constructions
Two sheets are mounted together on one leaf. The small sheet at left carries a vertical column of triangles and quadrilaterals numbered from the First to the Thirteenth, each annotated with brief notes ('Contiguous [figures]', 'change of adversary', 'not for the tenth conception'). The larger sheet at right bears constructions of straight lines radiating from and converging on points, several terminating in small circles, together with dense further writing that the bundle does not transcribe.

Column of thirteen numbered figures
A single column of small triangles and quadrilaterals runs down the left sheet, labelled in sequence from the First through the Thirteenth. Cross-references tie them together, e.g. the Fifth is marked 'for the first of the fifth' and the Ninth 'first of the fifth', while the Seventh and Thirteenth bear the note 'change of adversary'.
Radiating-line constructions on the right sheet
The larger right-hand sheet shows several bundles of straight lines springing from and crossing at points, some ending in small circles or rings. Dense handwriting fills the sheet around these figures; it is not included in the transcription and is not read here.
