Face. 



The cephalometric morphologic face height is the distance from 

 the menton to the nasion determined on the living person and 

 represents the height of the face without including any of the 

 cranium. This measurement varies to a considerable extent with 

 age, influenced largely by the condition of the teeth. In fact 

 this measurement in the edentulous aged would be valueless and 

 misleading for comparison not alone on account of the absence 

 of teeth but also because of the resulting absorption of the 

 alveolar processes. 



The average face height obtained for the male Quichua is 135. 

 the maximum 157, the minimum 122, with the range of variation 

 35. In the female the average is 127, with extremes of 152 and 

 112, and a variation range of 40. 



Our former observations on the Quichua showed the average 

 morphologic height of the face in the male Quichua to be 116, 

 the extremes 132 and loi, and the range of variation 31. As the 

 morphologic face height varies racially in the male from 103 to 

 127 and in the female from 107 to 117, the average face height 

 of 135 for the male and 127 for the female are so large in com- 

 parison that we suspect there may have been some error of tech- 

 nique, probably in locating the nasion too high. Possibly we are 

 here dealing with the face height estimated from the Glabella. 

 The Quichua probably occupy an intermediate position among 

 the races in respect to face height. 



The menton-crinion height gives what may be called the 

 physiognomic in contradistinction to the morphologic face height 

 or true face height. In the male this height averages 184, the 

 extremes are 200 and 154, with a range of variation of 46. In 

 the female the average is 170, the extremes 198 and 152, and the 

 variation range 46. The physiognomic face height of the female 

 is distinctly shorter than that of the male but has about the same 

 extent of variation. This is clearly shown by the seriation tables. 



The following selections from Martin's (9) compiled table of 

 physiognomic facial heights show a range from 170 to 192. The 

 male Quichua are therefore shown to be slightly above the 

 average and the female slightly below.
