Geometric constructions with a column of arithmetic
Triangles and circles with tangent lines, and an arithmetical operation
The leaf is covered with geometric constructions in faint ink: triangles, circles, spirals and tangent lines drawn across a stained surface, together with dense mirror-script notes. Of this only a single arithmetical operation is transcribed in the bundle, a column of figures (600, 24, 12, 22, 600, 244, 2, 25, 24, 100, 50, 600). Substantial further untranscribed writing accompanies the diagrams and is not reproduced here; the geometry is described from the drawings.

Triangles and circles with tangent constructions
The sheet is worked over with triangles, circles, spirals and tangent lines in a series of constructions. These diagrams carry untranscribed notes and are described from the image rather than read.
A column of arithmetical operations
A short arithmetical working is set out as a column of figures. The values recorded include 600, 24, 12, 22, 244, 25, 100 and 50.
