Voices, arithmetic operations and a group of flowers
Sound not carried beyond a distance, columns of figures, and a flower study
The upper half of the leaf is filled with columns of arithmetic operations set out over horizontal rules. A short line continuing the study of sound argues that where a single voice is not carried, an excessive number of equal voices will not be carried there either, with a semicircle of triangles lettered a, b, c, d, e, f, g, h. At the lower left a group of star-like flowers is drawn on a radiating fan of stalks, beside a note that in every three beats they give one bass-drum stroke.

Columns of arithmetic operations
The upper part of the page carries several columns of figures set out as calculations over horizontal rules, captioned as arithmetic operations.
Group of flowers on a radiating fan of stalks
At the lower left a cluster of star-shaped, many-petalled flowers is drawn springing from a fan of radiating stalks, captioned as a group of flowers.
An excessive number of voices not carried beyond a distance
Continuing the study of sound, the line reasons that where a single voice is not carried, neither will an excessive number of them be carried there, if that number is composed of voices equal to the one already considered.
