 corner teeth, their external figure, and the form of

 tolerable certainty, at a conclusion. The following 

 representation of the tables, taken in conjunction with 

 the coloured engraving of the seven-year old mouth, 

 will convey an idea of its appearance at that age. 

 The reader will remark the infundibulum of the 

 corner tooth has become circumscribed, being now 

 encircled by a flattened surface, which posteriorly is 

 of some width.
