The lower free end of the internasal suture. 

 A median, internal point, best located in a median 

 sagittal section as in Fig. 28. It is the median 

 point of the anterior clinoid process, and thus 

 marks the anterior margin of the sella turcica, 

 opposite the Klition. Called also tylion. 

 The point in the median line of the back of the 

 hard palate (interpalatal suture) where it is crossed 

 by a line drawn tangent to the curves of the posterior 

 margin of the palate (Fig. 25). 



The point where the temporal ridge crosses the 

 coronal suture. 



A median point where the base of the nasal spine 

 passes into the alveolar portion of the upper jaw. 

 This is best seen in a profile curve, where it lies 

 at the deepest part of the inward curve. It is 

 of use in the study of alveolar prognathism , as it marks 

 the upper limit of the alveolar region of the maxillary. 

 It lies about midway between nasospinale and 

 prosthion. 



The deepest median point in the supraglabellar 

 fossa. As this fossa is present only when there 

 is some development of the superciliary ridges 

 the point in question is frequently absent, or but 

 slightly marked, especially in females, but when 

 even a slight indication of it is present, its location 

 can be made out in a profile median curve of the 

 frontal bone, It serves to divide this curve into 

 the two portions, pars glabellaris and pars cerebralis, 

 the relative pioportions of which aid in the deter- 

 mination of the relative size of the supraorbital 

 crests. This point nearly coincides with the ophryon, 

 a point now seldom used. 



The highest median point in a skull, when placed 

 on the Frankfort Horizontal. 



The most lateral point of the zygomatic arch; a 

 point determined by trial measurement and not 

 by anatomical relations. 



The lowest point externally in the suture between 

 the maxillary and jugal (malar) bones. 



Measurements 



Prescribed Measurements of the Skull; International Agreement of 

 Monaco, 1906. From the time of Broca individual anthropologists were 

 in the habit of employing whatever measurements of the skull they found 

 desirable, without regard to the work of others, and, in addition to this, 

 did not correspond in the method of taking the same measurement. This 

 had the advantage of gradually increasing the number of measurements 

 employed, as new ones were being constantly devised by these independ-
