seen from fig. 82, the long diameter of the dental arch 
measured 62 mm. in the primitive Tasmanian, 60 mm. 
in the Heidelberg mandible, and 54 mm. in the Spy 
mandible. In width, however, the Neanderthal dental 
arch is much the greater. It measures 68 mm. in the 
Heidelberg specimen, 69 mm. in the Spy, and 61 mm. 
in the Tasmanian mandible. The peculiar adaptation of

i'rofessor Boule's reconstruction of the La Chapelle palate. 
a grinding rather than a cutting manner of mastication. 
From the arch of the lower teeth it is possible to re- 
construct the size and arrangement of the upper teeth 
and palate of the Heidelberg individual. In fig. 83 
this reconstruction has been carried out in order that 
a direct comparison may be made between the palate 
of the Heidelberg man and the Neanderthal variety 
discovered at La Chapelle-aux-Saints (see p. 151). The 
palate in the latter case was broken and the teeth lost. 
Professor Boule was therefore obliged to reconstruct the 
palate in that case also. The palatal area in each is 
almost the same — 35 cm." in the La Chapelle specimen, 
367 cm.- in the Heidelberg specimen, and 367 cm.- in
