Rising Three Years (Figs. 65, 66, 67). — From in front, in the upper 

 jaw, the two permanent pincher teeth are seen not 3'et opposite to the 

 level of the intermediate deciduons teeth ; below, the adult pinchers are 

 just coming through the gum, showing a small portion of their anterior 

 face. In profile, the intermediate teeth are very much worn, and the 

 constriction on their neck is pushed out bej'ond their gums ; the corner 

 teeth are much shortened ; the dental table shows slight wear of the 

 superior pinchers, which has been produced by the eruption of these 

 teeth before the inferior temporary pinchers had fallen out, and, conse- 

 quently, the}' have worn against the latter. The intermediate teeth are 

 completely leveled ; the corner teeth are much used.
