Marsh — On the Pithecanthropus erectus, 



The facts relating to the discovery itself, and the position in 

 which the remains were found, as stated by Dr. Dubois in his 

 paper, together with some additional details given to me per- 

 sonally, convinced me that, in all probability, the various 

 remains attributed to Pithecanthropus pertained to one indi- 

 vidual. Under the circumstances, no paleontologist who has 

 had experience in collecting vertebrate fossils would hesitate 

 to place them together. 



In figure 1, below, a geological section is given, showing the 

 series of strata exposed in the bank of the river Bengawan, 

 near Trinil, in central Java, where all the remains of Pithe- 

 canthropus were found. The exact positions of these various 

 specimens when discovered are also indicated. 



Figure 1. — Section of the bone strata at Trinil. (After Dubois.) 

 A, vegetable soil ; B, sand-rock ; C, bed of lapilli-rock ; D, level in which 

 the four remains were found ; E, conglomerate ; F, clay -rock ; G, marine 

 breccia ; H, rainy season level of river ; I, dry season level of river. 



The above section, taken from Dr. Dubois's Dublin paper, 

 makes clear many points as to the locality where the discoveries 

 were made, which were left doubtful in the original memoir.
