8ef, ab will vibrate longitudinally, provided they are rigidly connected at g. But if this joint is imperfect, the same result will not follow. Again, by exciting c at an angle of about 40° with the original direction, as hi, the second rod, ab, will vibrate transversely instead of longitudinally. It is obviously unnecessary, therefore, to make the case of the violin post an exception to this general law, since neither the post nor the bridge are rigidly connected with the belly. Again, in his "Mémoire sur les Communications des vibrations," Savart himself states the following case amongst many others:—"If a rod falls perpendicularly upon another rod at a point in this latter, held in a state of rest by a rigid obstacle, the first being caused to vibrate transversely, the second will also vibrate transversely," as in the following Fig. one of two readings
