"The ground-floor apartments next to the street have small wooden grated windows, placed sufficiently high to render it impossible for a person passing by in the street, even on horseback, to see through them. The windows of the upper apartments generally project a foot and a half, or more, and are mostly made of turned wooden lattice-work, which is so close that it shuts out much of the light and sun, and screens the inmates of the house from the view of persons without, while at the same time it admits the air. They are generally of unpainted wood; but some few are partially painted red and green and some are entirely painted. A window of this kind is called a 'roshan' or, more commonly, a 'meshrebeeyeh.'

"Sometimes a window of the kind above described has a little meshrebeeyeh, which somewhat resembles a roshan in miniature, projecting from the front or from each side. In this, in order to be exposed to a current of air, are placed porous earthen bottles, which are used for cooling water by evaporation."
