National Geographic : 1938 May
© National Geographic Society Painting by Elie Cheverlange IN AFRICA NATURE HAS FITTED ONE MONKEY FOR LIFE ON THE GROUND, ANOTHER FOR DWELLING IN TREES The HUSSAR (left), also known as the Military or Patas, shows a remarkable development of leg and arm muscles, while the hands and feet have become stubby and pawlike from generations of running over rocks and sandy plains. The result is more doglike than simian. Incontrast, the RED HEADED MANGABEY is equipped for an arboreal existence, with sinewy arms and four strong hands for clinging tobranches. Itpurses its lips asiftobekissed.
