WINDOW

(Quasi wind door.) In Architecture, an aperture in a wall for the admi ion of light and air to the interior. In distributing windows so that there be had a sufficiency of light, it is usual to make the piers or intervals between them never le than the width of the window, and never more than two widths of the same. Where it is required to ascertain the total area of light nece ary for a room, the following empirical rule is frequently used Multiply together the length, breadth, and height, and extract the square root of the product, which will be the area of light required.
