THE ANTIQUITY OF MAN 
Solo or Bengawan, a stream which, rising among the 
volcanic hills of the province of Madiun, in the central 
part of Java, pursues a north-easterly course to the sea. 
A native hamlet named Trinil is near the scene of Dr 
Dubois' explorations. A section of the deposits which 
form the east bank of the Bengawan, with the stratum 
in which the remains of Pithecanthropus were found, is 
shown in fig. 89. 
The deposits are of the kind we have already studied

in the river valleys of Europe. The stratum which 
directly concerns us is the fossiliferous bed, about 4 feet 
in thickness, lying at the level of the present stream — 
the Solo or Bengawan. The fossiliferous stratum is 
well named. Between 1891 and 1894, Dr Dubois 
removed from this layer fossil bones representing twenty- 
seven different kinds of mammals — most of them 
belonging to species which are now extinct. After 
comparing the animal remains thus discovered with 
these which are found in Pliocene and Pleistocene 
deposits of India, Dr Dubois came to the conclusion that
