The femur of the skeleton to which this skull belonged is 19'1" 

 in length, and has its various ridges, and especially that which is 

 in relation with the insertion of the glutseus maximus, considerably 

 developed. Thehumerus is 12'7" long, and by examination of this 

 bone, of the femur, of the skull, and the lower jaw, we are enabled 

 to say that they belonged to a strong male in the later part of the 

 middle period of life, probably about 50 years of age and 5' 9" in 

 height. In the greater obliquity of its forehead and the larger deve- 

 lopment of its supraciliary ridges this skull differs from the one which 

 precedes it, and forms a connecting link between such skulls as that
