Fig. 129.— The proportions of the head viewed in front. 



From the auditory hiatus, G, to the maxillary spine, F, it is the same distance as from this 

 point to the end of the lips, E, and still better to the end of the teeth. 



The line GC, from the auditory hiatus to the poll, equals one-sixth of the head, or 10 

 centimetres; the line AG, from the orbital arch to the auditory hiatus, is a little longer and 

 measures 12 centimetres.
