figures a certain chimpanzee in which the tip of the 



lateral upper incisor is submerged in a transverse 



incisal edge and even the outer rim is vertically 



developed, so that the crown as a whole is clearly 



approaching the human type. 



The great outstanding difference between the 



dentition of man and that of his anthropoid 



cousins lies in the fact that in man the canine 



teeth, even in the milk set (Fig. 76) are much 



reduced in size, with rounded crowns and obtuse 



tips that project but little above the level of the 



adjacent teeth, while in the anthropoids, especially 



the males, the canines form large sharp-tipped 



tusks. If, however, the fossil lower jaw found at 



Piltdown, England (Fig. 45C), belongs with the 



human Piltdown skull, as nearly all authorities 



now believe, it affords a clear case of an ape-like 



canine belonging in a human jaw; only it should 



be noted that the Piltdown canine is much more 



like the lower canines of certain female gorillas, 



which have not attained the tusk-like stature of 



male canines. The human canines may indeed 



be most reasonably regarded as reduced and
