The lines to represent the posterior border of thepalatal bone, malar process, and suture connecting the malar bone arethen made, which represent the extent of the growth from the time ofthe eruption of the second temporary molar to that of the eruption ofthe first permanent one. The permanent central and lateral incisorsare then drawn in position according to the lines of the arch it is in-tended to represent, in advance of the temporary ones. The first andsecond bicuspids are then placed in position. These are followed bythe insertion of the cuspids, second and third permanent molars, withthe proper enlargement of the other portion of the drawing. Fig. 4.
