Then you will see that it has finger-bones at the end, then hand-bones next, then bones that run from the wrist to the elbow, and then one bone that runs from the elbow to the shoulder--almost the same bones that people have in their fingers, hands, wrists, and arms.

"I could go through all the inside parts of birds, and show you something like the same parts in people,--stomach and bowels, to take care of the food they eat and turn it into blood to nourish them; lungs to breathe with, and keep the blood pure; heart to beat and thus pump the warm blood into all parts of the body; brain and nerves, which are what birds think and feel with, just as we do with ours; and all their bones, which together make what we call the _skeleton_, or framework of the body, to keep the flesh in shape and support the other organs."
