Therefore the positions of the different parts representing the spine in fig. 679. command and regulate these changes. allowing of free rotation upon a rigid per- pendicular body A a ; let the free extremities of these bars be kept apart, so that the bars may at all times be parallel to each other. In this condition a certain distance exists between the bars, and a certain distance be- tween their free extremities and the perpen- dicular body A a. Let B represent the same bars moved into another position, resembling that of the ribs; in this position, the two conditions seen at A are altered. The perpendicular distances between the bars are diminished, and the distance between the free extremities of the bars and the body B b is likewise diminished. If the direction of this motion were still continued, the bars would ultimately touch each other, and their free extremities would be still nearer to the body B b. But let the bars be elevated, as in c c, and the same condition obtains as in the bars at B b, viz., they approximate each other, and the free ends come nearer to the body, c c. In this case the bars only have moved ; but the same effect can be obtained without moving the bars. Let A B (fig. 678.) be two bars at their maximum distance, while horizontal; at a b, and a' b'', they have nearly attained their minimum perpendicular distances, though still hori- zontal, because the rigid
