By William Paley.
Now observe what would have been the inconveniency, i.e. both the superfluity and the defect of articulation, if the case had been inverted; if the ball and socket joint had been at the knee, and the hinge joint at the hip. The thighs must have been kept constantly together, and the legs have been loose and straggling. There would have been no use that we know of, in being able to turn the calves of the legs before.
