That table in the Snape's edition is actually done with the Koch Signs from what I've seen. Not really anything found per se, besides the little squares. Those look like scans. The fourth edition on the other hand, which I've seen in person in detail many times does have a found table there and it is not the same one which you posted.
Well drat, you are definitely right. I guess I was thinking of some other images when I saw those illustrations. Still looks like something that could be incorporated into the book though.
That aside, just finished the text portion of the section on purifying Caxambu roots.
I still want to put some illustrations in there, but it was still fun to write.
