26o THE ANTIQUITY OF MAN 
From one point of view the expedition was eminently 
successful. A great harvest of fossil forms was collected, 
but no further trace of Pithecanthropus was discovered. 
Seventeen specialists examined and described the great 
collections brought home by the Selenka expedition. 
The conclusions drawn by Dr Stremme and Dr Janensch 
from a study of the mammalian remains was that the 
fossiliferous bed was late Pliocene in date of formation, 
but those who examined the other collections fixed its 
date in the older Pleistocene. In this also we see a 
resemblance to the Cromer forest beds, which oscillate 
in the geological scale on either side of the border-line 
between Pliocene and Pleistocene. 
We now proceed to examine the kind of being who 
lived in Java when the Cromer forest beds were being 
formed in Ndrfolk. The picture has to be built from (i) 
the vault of a skull ; (2) a left thigh bone ; (3) three 
teeth, two of them belonging to the upper molar series — a 
second of the left side, a third or wisdom tooth of the 
right side, the third or remaining tooth being a second 
lower premolar of the left side. There can be no doubt 
that all the parts, if not belonging to the same individual, 
at least all belong to the same species. They were found 
at the same horizon of the fossiliferous stratum. There 
is no question of a burial here, for the various parts 
were scattered over a distance of twenty paces — spread, 
apparently, by the running waters of the stream. If we do 
not admit that the femur, the teeth, and the calvaria, which 
lay near each other in the bed of an ancient stream, are 
parts of the same individual or same kind of individual, 
then we must make a very improbable supposition. We 
must suppose that the femur is that of a man showing 
a few, minor, ape-like traits ; that the teeth are from 
another human being in which certain simian features 
were manifest ; and that the calvaria belonged to a large- 
headed anthropoid showing marked human affinities. 
We cannot conceive that chance could bring three such 
strange individuals side by side in one narrow area of the 
bed of a stream. With Dr Dubois, we think there is
