TABLE 1 

 Position of the transverse abnormal suture on the frontal hone of adults 



suture is 18.8 mm., and the distance between the intertuberal 

 Hne and the suture 18.3 mm. The average of the two negro 

 skulls of Fischer and that of the author's case is, for the corre- 

 sponding measurements, 23.2 and 12.6 mm. respectively. There- 

 fore the suture in the negro seems to be relatively higher above 

 the nasion and closer to the intertuberal line than in the white. 

 The exact determination of the position of this abnormal suture 

 is also of importance in the explanation of its origin, as will be 

 seen later. 



Upon examining the inner surface of the skull, the suture is like- 

 wise found to be extensive (fig. 3). Incidentally it might be stated 

 that the crista frontalis interna is only moderately developed, 

 as was the case in the skull with the same anomaly described by 

 Rauber ('03). In two of Schwalbe's cases the crista frontalis 

 was examined, and found in both to be broad and blunt. For 

 the most part the abnormal suture on the inner surface communi- 

 cates with that on the outer surface, often allowing the passage
