Skeleton of a Bird.

The frame-work of a bird is one of the most curious and interesting things in nature; and if we examine it carefully, we cannot but admire the ingenuity and skill of its great Creator. What mechanic, save the Author of nature, could have executed a piece of mechanism so complicated, so delicate, and that yet works so admirably? Think of the rapid motion of a bird in its flight; the quick vibrations of the wings; the sudden bendings of the neck and tail; and consider that all these are effected by muscles, which operate like the ropes of a ship. How slow and difficult are the evolutions of a ship, which is one of the wonders of human art; how swift are the evolutions of a bird, which, however, is only one among the thousand wonders of nature!

Another curious thing about the skeleton of a bird, is this—all the bones are hollow and very thin, yet they are very strong. Now, why are they so thin and light? Because the bird is to fly in the air, and therefore it is necessary that his body should be as light as possible. How wonderfully the Creator seems to have foreseen all things, and to have contrived them in the best possible way to answer the purposes that he had in view!
