Madeleine Dubois-Volkov's lab was well-lit, crammed full of a strange mixture of equipment; modern beakers and ancient cauldrons, a well-cared for old microscope sitting beside a jar holding a trapped flitwisp, a multitude of glass vials in a Muggle refrigeration unit that appeared to be working via magic rather than electricity, chemical compounds all muddled up with potions ingredients... Hermione's eyes swept the large cellar, over all the equipment, and landed on Enseignante Dubois-Volkov – the woman's ash-brown hair was twisted up in a loose bun with a pen jammed through it to keep it up, a pair of old-fashioned spectacles was perched at the end of her nose, and she wore Muggle clothes with her wand sticking out of her trouser pocket.
