APPENDIX B. 



Of course I tried to collect crania of the Papuan tribes, with which the expédition 

 came in connection. In Swart-valley I did not find a single human bone. It appeared that 

 the Timorini buried their deaths. I heard from the members of the second expédition that 

 the indigènes cremated the corpse first; as was witnessed two times. As for nearer informa- 

 tion on this subject, we will hâve to vvait for the ethnological report, concerning both the 

 expéditions. Headhunting appeared not to be practised as is easily to understand in regard 

 to the lack of a useful instrument. 



In Pioneer-bivouac we collected twelve skulls. I asked the bird-hunters (birds of paradise 

 are abundant in those régions) who came repeatedly in our bivouac, to bring me the skulls 

 they might be able to obtain in the villages they would visit and in this way I got four 

 crania. On the other hand I told the Papuans who came into our camp that I wanted to 

 buy ail human bones they might hâve in their houses and so I obtained another five. The 

 last three were sent to me by Dr. DE ROOK who also accompanied the second expédition; 

 he also got them from the Mamberamo-Papuans. Though it is highly probable that the five 

 skulls, I got directly from the Papuans, are from their own tribe, it is not impossible that 

 they took them from other Papuans or even . . . . from killed Malay bird-hunters! In respect 

 to the skulls, brought by the hunters, the incertainty is still somewhat greater. This does 

 not mean that studying thèse skulls is without any value, but only that one should not draw 

 his conclusions from some deflecting qualities of one or two of thèse skulls, as exactly those 

 might be of foreign origin. For the rest, this chance of being of foreign origin is, so far 

 inland, not great. 



Next I give the list of measurements of the twelve crania. N°. I and 2 made strongly 

 the impression of being female skulls, also n°. 8 and 9, of which the Papuans who brought 

 them, stated the same and told even the names of the women of whom they originated. 

 Ail the other skulls made a maie impression. 



In the „Koloniaal Instituut" of Amsterdam I found a séries of 14 skulls from the 

 Schouten-Islands (Biakj in the North of the Geelvink-Bay, of which I calculated the cranial 

 indices:
