In my second example, from a female eleven and a half 

 years old, the so-called third horn was a distinct cap of bony 

 material fixed to the fronto-nasal elevation and lying directly

 above and concave below ; and its anterior edge reached to 

 about 6 lines behind the most forward portion of the nasal 

 elevation. The cap accurately fitted the skull-contour, being- 

 adherent thereto by a dense cartilaginous-like periosteum, 

 015 inch at its thickest part. The representations A and B 

 in fig. 4 give the precise shape of the piece as seen in profile 

 and inferiorly. 



Considerable force was required to remove it, so adherent 

 was the fibro^jlastic material to the skull. In effecting this,
