distinction is difficult. The little difference that there is, is limited (as not sel- 

 dom in other cases) to the trituration surface of the crown. 



A good deal of weight has been placed upon the excess in the Piltdown teeth 

 of their length over the breadth. It was apprehended as an inferior character 

 and one placing the teeth nearer in type to those of the chimpanzee than to 

 those of man. Upon closer examination into the subject this view is hardl}- 



LENGTH, BREADTH AND INDEX OF THE PILTDOWN AND OTHER 



MOLARS 



' Taking all the available specimens, hence also those in which one of the two anterior molars 

 is missing, we find one sole tooth, the first right molar of male chimpanzee jaw No. 176,227, U. S. 

 N. M., in which the index comes near being that of the Piltdown teeth; the dimensions of this molar 

 are: L., 12. o; B., 10 o; Index, 8i.3. Individual human molars of this form could doubtless also be 

 discovered. 



sustained. On one hand we find individual human teeth both recent and ancient 

 that closely approach the Piltdown molars ; while on the other it is found that 

 chimpanzee molars also are in general relatively shorter. 



Among the remains of early man the majority of the bones and teeth are, 

 regrettably, so imperfect that exact measurements of the molars are impossible ; 

 but a remarkable resemblance to the Piltdown teeth is found in the molars of 

 the recently discovered lower jaw of Ehringsdorf, Germany. The figures on this 

 page show the measurements of the teeth in various specimens.
