Fig. 1 illustrates a design for the corners of Oxford picture frames. The lozenges are level and form the top surface, the interior being carved 1/8 in. deep and scored. A section of the lozenge is seen in Fig. 2, and a section of the chamfer part of the moulding in Fig. 3. For frames of large size, the length midway of the sides is relieved with an intermediate ornament, shown by Fig. 4. The moulding illustrated is Jin., so that for larger or smaller sizes the lozenges should be correspondingly reduced or enlarged. The frame is finished in the natural wood, being polished or varnished.
