SSSusan:
Actually, someone on another list said that this rang a bell for 
her, and she found the following from Chapter 14 in PS:

"It was hard to relax with Hermione next to you reciting 
the twelve uses of dragon's blood or practicing wand movements."

So I guess we *did* see it in canon that Hermione knew all 12; it's 
just that apparently no one around her paid attention to it... or 
apparently felt the need to study the same material she was studying?

Actually, I guess this means JKR *may* have changed her mind, from 
Hermione coming to school with this knowledge, to her having learned 
it while studying at Hogwarts.  If the latter, I wonder if all the 
other students in the class were *supposed* to be learning the 12 
uses, too?

significance whatsoever
