Goddlefrood:

I agree on this point. There was something I wanted to add to 
the discussion of the SNEAK pustules even though it may not be 
thought possible to do so.

Why, if bubotuber pus is effective against the more stubborn 
froms of acne (p. 172 - GoF, Blomsbury Hardback), did Poppy 
not apply it to Marietta?

Madam Sprout had given a large supply of the stuff to Madam 
Pomfrey and it would be well known to her, methinks. Perhaps 
Poppy doesn't like sneaks and felt it apposite to leave Ms. 
Edgecombe with her pustules.

Only a small thought.
