Text leaf with a dense marginal note

The leaf carries mirror-script prose broken into short sections, several opened by a brief heading, with a separate column of much smaller, densely written notes down the left margin. The main ink is pale grey in the upper half and darker below, and a strip of writing shows along the bottom edge; no figures or diagrams are drawn. None of this text is transcribed in the bundle, so its subject matter is not reported here. The sheet is one of the discursive leaves cut from Manuscript A.
