be reduced to 112,2. We see that in respect to the height of face the three tribes are 

 shovving no différence. Consequently the facial index of the coast- and Mamb.-Papuans becomes 

 much greater than that of the Timorini, for there was a fairly large différence in the facial 

 breadths. The values are resp. 84,8, 85,5 and 81,6. 



We can draw the following conclusion: the principal différence betvveen the heads of 

 the coast-Papuans and those of the Timorini is lying in the little head-breadth of the former. 

 Therefore the measures of the face are apparently handicapped ; yet they approach so closely 

 those of the Timorini as may be expected under the given circumstances. It stands to reason 

 that the width between the zygomatic arches is most of ail subject to the influence of the 

 cranial breadth; the forehead and 



the jaw are indeed at a greater Diagram XIX.

As I cannot produce sufïïcient 

 information about the Index cepha- M 

 licus of the Mamb.-Papuans, they 

 cannot figure in the comparison. As 

 for the form of the face, they seem Med 

 to approach the coast-Papuans. 



According to the division of 

 Rudolph Martin [1 12], the Timo- Med 

 rini are broad-faced (euryprosope), 

 while the coast-Papuans are meso- 

 prosope. 



With the Dyak the case is 

 quite différent. In respect to the 



Timorini, the breadth of the forehead Facial Index ' 



is with 107,1 mm. still larger than 



that of the skull; hence the Ind. fronto-pariet. surpasses with M. 71,4 that of the Timorini 

 considerably. The bizygomatic breadth is greater than that of the Timorini, but not more 

 than is corresponding with the larger head-breadth; the Ind. cranio-fac. is therefore nearly 

 the same, viz. 94. But the width between the jaw-angles is remarkably large: M. 110,2 mm. 

 and so the Ind. jugo-mand. reaches 78. The facial height is the same as that of the Papuans, 

 M. 112.3 mm., consequently the facial index is smaller : 79,5. 



Conclusion: The différence between the Dyak and the Papuan skull is two-fold : 

 firstly the head-breadth of the former is greater, so that the skull inclines considerably to 

 brachycephaly, and secondly the face is broader and the différence in the facial part 

 is even larger than in the cranial part of the head. The fact that the différence in 

 breadth, which is strongest in the jaw, is more pronounced in the forehead than in the 

 zygomatic arches, makes the supposition untenable that the larger head-breadth should be 

 the conséquence of a broad skull-base, in its turn resulting from the largely developed 

 breadth of the jaw.
