Lunes in quarter-and-eighth proportion, with a letter draft

Quadrant figures similar to fractions of a circle

In the 'quarter and quarter' figure a b equals c and each part is similar to a twelfth of its circle. In the analogous figure a, b, c are equal and each is similar to an eighth of its circle.

Equalising lunes from doubled circles

When the lune-pyramid is made of curves born of circles double one another, one removes from the larger circle a half portion and from the smaller a whole one; being the quarter with the eighth, they then come out equal.

Draft of a personal letter

In ordinary script, apart from the geometry, is a broken draft addressed to someone: since leaving, the writer has not written because he wished to, expressing no doubt, and noting that Domenico told him to say everything.
