MUSCLES OF MAN 



the greatest stress is laid in walking. As to muscles, the glutaeus 

 maximus is more developed in Man — the Ape which most nearly 

 approaches him being the Gorilla, in which animal the life is 

 less thoroughly arboreal than in some others. The so-called 

 "scansorius" is only present in Man as an occasional occurrence.

The rudimentary character of the ear muscles for the movement of 

 the external ear in M:in has often been insisted upon, as also 

 their occasional functional activity. But here and elsewhere, so 

 numerous are the abnormalities, that " the gap which usually 

 separates the muscular system of Man from that of the Anthro- 

 poids appears to be completely bridged over." These are words 

 of Professor Wiedersheim quoted from Testut, and express a final 

 summary of the matter of muscles in ]\Ian and the Apes.
