Reversed (perverse) order of proportion
Red-chalk bracketed proportion diagrams
In red chalk the single legible word 'perverso' (reversed, set the wrong way about) heads a set of bracketed proportion diagrams, continuing the study of how a proportion behaves when its terms are turned around. Three-bar brackets group columns of numbers on the sheet. Further faint script and show-through from the facing leaves is visible but not included in the transcription.

The 'perverso' (reversed) arrangement
The note is headed 'perverso', meaning reversed or set in the wrong order. It labels bracketed groups of terms in which a proportion is read against its natural direction, completing the sequence begun on the preceding pages with 'eversa' and 'direct order'.
