Text leaf with paragraph headings in mirror-script

A page of Leonardo's mirror-script arranged as several paragraphs, a few introduced by short centered sub-headings, with the ink noticeably faded across the middle of the sheet. The oval stamp of the Bibliotheque de l'Institut de France and a red folio number appear at the right margin, and a further line of writing runs along the lower edge. No drawings appear on the leaf. The prose is not transcribed in this bundle and its content is therefore not reported.
