fig. 165 the dimensions are incompatible with the

It is clear that we cannot reconstruct the Piltdown 
mandible on such lines and apply it to the skull. That 
difficulty was appreciated by Dr Smith Woodward in 
making his original reconstruction. The condyles, to fit

the skull, must be placed at least 120 mm. apart. If, 
then, the teeth were to form parallel rows as in 
anthropoids, a great width must be given to the front 
part of the jaw. The right half of the mandible is so 
fractured in the region of the chin as to leave some degree 
of uncertainty as to whether or not the broken extremity 
actually reaches the middle line of the chin. Dr Smith 
Woodward has taken advantage of the doubt in his 
reconstruction and widened the region of the symphysis
