Different parchment color through Herbal section?

Thanks for the plots! 

(AI may not destroy humanity, but it is destroying science because each single scientist now can write far more technical papers than anyone can read, including himself. And that even counting only correct stuff, not slop!)

By the way, I noticed a curious detail.  The bifolios f3+f6 and f4+f5 both have a triangular sliver missing on the top free corner of their second folios (f5 and f6).  The missing piece is ~15 mm wide at the top and extends vertically down to mid-page.  Curously there is a "ghost" of that missing sliver on the verso side of the matching folios (f3 and f4), where the vellum is much darker than on the rest of the folio.  

My interpretation is that (1) the two bifolios were originally folded as they are now, rather than flipped inside-out, but (2) they both were kept as unbound siingulions long enough for dirt and light to stain the vellum of f3 and f4 where it was not covered by f6 and f5, respectively.

By the way also, this is again the BL image of the spine that I posted earlier:
   
In this photo we can clearly see the hair follicles.  I suppose that this material is parchment not vellum, and it was not prepared for writing (or the chalk coating was washed away when it was (re)used for binding).  Notice how dirt accumulates in the follicles rather than on the exposed surface of the vellum. 

All the best, --stolfi
