If theexterior must be of domicalform, while on the interiorthere is a suspended or falseceiling of some kind, then only the outside edges of the ribs mustlie in the conical or spherical surface, so as to receive the roof board-ing, while the inside edges may be left rough or shaped to anyother form.
