Beauty of Potions by Snape

'As there is little foolish wand-waving here, many of you will hardly believe this is magic.

I don't expect you will really understand the beauty of the softly simmering cauldron with its shimmering fumes,
the delicate power of liquids that creep though human veins,
bewitching the mind, ensnaring the senses...

I an teach you how to bottle fame, brew glory, even stopper death - if you aren't as big a bunch of dunderheads as I usually have to teach.'

The Potions Master - Pg 146
