femur = 100, the European presents tlie following proportions : 

 tibia = 82-5; foot =52-9; whilst in tlie chimpanzee the pro-

 the extremity of the limb acquires the greatest length. 



This organ, compared with the human foot, is a real hand. 

 True, the fingers are somewhat shorter, the thumbs larger and 

 thicker than in the anterior hand ; but still it is a hand, with 

 a flat lower surface, well-separated, moveable, drawn-out fingers, 

 with opposable thumbs, and a long furrowed palm. On com- 

 paring a sketch of this hand with that of a human foot, we 

 first perceive that Burmeister was right in designating {Geolo- 

 (/Ische Bilder) the foot the specific character of humanity. The 

 strength and length of the great toe, which generally exceeds 

 in man those of the other toes ; the smallness and imperfection 

 of the other toes, which can generally be moved only together.
