Fic. 25.—Perforation of the humerus (supra-condyloid foramen) in 
three species of Quadrumana where it normally occurs, and in Man, wheie 
it does not normally occur. Drawn from nature (A. Coll. Surg. Mus.). 
(11) Flattening of tibia —In some very ancient 
human skeletons, there has also been found a lateral 
flattening of the tibia, which rarely occurs in any ex- 
isting human beings, but which appears to have been 
usual among the earliest races of mankind hitherto dis- 
covered. According to Broca, the measurements of 
these fossil human tibiz resemble those of apes. More- 
over, the bone is bent and strongly convex forwards, 
while its angles are so rounded as to present the 
nearly oval section seen in apes. It is in association 
with these ape-like human tibia that perforated humcri 
of man are found in greatest abundance.
