Fig. 224. — Tables of incisors (nat. size). 



When the mouth is closed, the central incisors of both jaws 

 are fully in contact, and the lateral incisors are partly in contact. 

 The corner incisors of the upper jaw have made their appearance, 

 but those of the lower have not yet penetrated the mucous 

 membrane which covers them, although they can be felt under- 

 neath it.
