Seven Years (FiQ;s. 89, 90, 91). — There is nothing- speciul to be seen 

 in front excei)t that the teeth are whiter, — due to the disappearance of 

 the cement, wliich lias been worn from the surface of tlie enamel. In 

 ]>rofile it is seen that the table of the inferior corner tooth is narrower 

 than that of the superior from the front to behind, so that a notch is 

 formed on the posterior corner of the latter. The incident of the tooth 

 is less perpendicular than at six years. The cups of the tables of the 

 intermediate teeth are wider from in front to behind and narrower from 

 side to side. In the corner teeth the wearing- surface is larger and the 

 cups are smaller. The pineher teeth are oval and the intermediate teeth 

 commence to become so. In this month, again, the superior corner teeth 

 are fissured on their posterior borders.
