Other measurements are given in the text (especially p. ii). The 

 cranial capacity was estimated at somewhat over i,ooo cc. (p. ii). 

 The characteristics of the skull indicated, Dr. Dubois believed, that 

 it " represented a form which must be classed in a different genus 

 from those of Gorilla, Orang and Man " ; it " approaches the skull 

 of Man in its approximate size and its vaulting, showing, nevertheless, 

 considerable resemblances to that of the chimpanzee and in form to 

 that of the gibbon." The various characteristics of the fossil skull 

 indicated that it belonged to a female individual. 



The femur, according to Dubois, showed close resemblances to that 

 of man, although also some differences. Its bicondylar length was 

 45.5 cm. which, he believed, equaled that of a man of about 170 cm. 

 in stature. The shaft was less curved forward than in man, and 

 approached less the prismatic form. The circumference of the bone 

 at the middle was 9.0 cm., its lateral diameter 2.75 cm., both much 

 as in man. The popliteal plane, however, instead of being slightly 

 concave or nearly flat as in man, is perceptibly convex ; this character 

 is never met with in human femora. The angle of the neck, 175°, is 

 near the average in man. The transverse and vertical diameters of 

 the head are respectively 2.25 and 2.15 cm., agreeing closely with 

 human dimensions. The intertrochanteric ridge differs from that in 

 man, approaching that in an orang. The rest of the characteristics 

 of the bone are essentially human-like, with here and there some 

 deviation. The form of the lower articulation is as in man and unlike 

 that in any of the anthropoid apes. 



Judging from the length and strength of the bone Dubois believed 

 himself justified in assuming that the upper part of the body of the
