Jalousie

Whose jalousie is this?

A small lofty room, with its window wide open, and the wooden jalousie-blinds closed, so that the dark night only showed in slight horizontal lines of black, alternating with their broad lines of stone colour.

Nowhere the glitter of a glass casement; Venetian blinds, jalousies, closed every window, and rooms projected in all directions to catch the luxury of a through-draft of air.
