7. -Biauricular breadth (t-t) 



8. Bimastoid (ms ms) 



9. Biocular breadth (ex-ex) 



10. Interocular breadth (en-en) 



11. Interpupillary distance (with pupillometer) 



12. Breadth of palpebral opening (Subtract No. 11 from No. 10) 



13. Nasal breadth (al-al) 



14. Oral breadth (ch-ch) 



15. Auricular height (t-v); projection, i.e. difference of level between 

 tragion and vertex; may be done either by anthropometer as in the case 

 of the skull or by subtraction. 



16. Height, vertex to subnasale (v-sn) by subtraction, or in projec- 

 tion with anthropometer. 



1 7 . Physiognomic facial length (tr-gn) ; only in individuals with normal 

 extent of hair. 



18. Morphological facial length (n-gn) 



19. Physiognomic superior facial length (n-sto) 



20. Morphological superior facial length (n pr) 



21. Nasal length, in ground plan (n-ns); used for nasal index with 13 



22. Nasal length, along profile (n-prn) 



23. Nasal height, projection from face (prn-sn) 



24. Frontal height, physiognomic (tr-n); only in individuals with 

 normal extent of hair. ; 



25. Height of mucous lips (li-ls) 



26. Height of entire upper lip, (sn-sto) 



27. Height of entire lower lip (sto-slm) 



28. Height of chin (sto-gn) 



29. Physiognomic ear length (sa-sba) 



30. Physiognomic ear breadth (pra-pa) 



31. Morphological ear length, cf. ear of horse, sheep etc. (t-tu) 



32. Morphological ear breath (obs-obi) 



2. Angles. 



33. Profile angle (line FH with line n-pr prolonged) 



34. Camper's facial angle (line meat-sn with line on-sn) 



35. Superior facial angle (line meat-pr with line meat-n) 



3. Girths. 



36. Horizontal circumference of the head. Put the "O" of the tape 

 measure at the glabella with the left hand, lay tape with the right hand 

 along the left side of the head over what appears to be the opisthocranion 

 and thence around to point of beginning. Shift until correct, with the 

 tape placed horizontally and drawn over the opisthocranion. 



37. Sagittal arc; with the tape, from nasion, over top of head, to 

 inion, in the median plane. This does not quite correspond to the like-
