The third molars have not erupted.(About fifteen years.) THE GROWTH OF THE JAWS 403 the relation of the permanent incisors and cuspids to the tem-porary ones. In the lower jaw the temporary centrals havebeen lost and the permanent ones are forcing their waybetween the temporary laterals. The crowns of the centrals Fig. 313
