The lungs of these mountain inhabitants are larger, and their veins contain about two quarts more blood than those of sea-level dwellers.
The Indians' slower-beating hearts are about one-fifth larger than ours, their arms and legs are shorter, and their eyes are covered with a fold of skin to keep the eyeball from freezing.
