Pareidolia, but underwater: What is under the green paint?

[Jorge_Stolfi]

What about f35r, left side of the plant?

Wait, wait -- I am still working on the first real case...

But I don't care much about the Herbal images, since I believe that they are mostly random "Frankenstein monsters" created by the Scribe.  Many leaf veins and outlines have been painted over, but I don't think they carry any useful information.  So those puzzles will get very low priority in my queue...

The figures in Bio, on the other hand, seem to be more meaningful, even if they are disguised -- as organs or as baths, depending on your theory -- and have been badly affected by fading and retracing.  Any drawing details that were obscured by those green pools may perhaps give us additional clues about the nature of the drawings.

All the best, --stolfi
