Snape's potions puzzle in PS

No: HPFGUIDX 49123

You know, the one Hermione solves to get Harry through to the mirror.

I have uploaded my analysis of the puzzle in the files section 
here.  Go to 

http://groups.yahoo.com/group/HPforGrownups/files/Essays

and click on Snape's puzzle.doc

My main finding is that the puzzle is a fair one (that is, the clues 
are not contradictory and point to a unique solution), and that 
Hermione would have been able to identify the contents of every 
bottle.

Any thoughts?
