30. „ fi-om one external auditory opening to the other 30

34. „ between the internal corners of the eyes - 34 



35. „ between the points of attachment of the lobes 



of the earf -.-....35 



36. Breadth of the nose - - - - - 36 



* The following measurements may then be made. From the point taken 

 by the callipers on the zygoma to the commencement of the growth of the 

 hair on the forehead, in the median Une, and also to the point of the chin. 

 By this the most prominent point of the cheek bone in the facial plane may 

 be determined. 



t Measure also the breadth of the forehead in the horizontal line : — 



(a) From one part of the linea semicircular is, which may be felt like a 

 crista beneath the skin, to the other. The spot where the convexity in front 

 is greatest should be selected. 



(6) In the same horizontal measure the greatest breadth of the forehead, 

 from the beginning of the growth of the hail', fi-om one temple to the other.
