Animals below insects, as radiates and mollusks, are all entirely incapable of sound. Among reptiles, certain of them, such as frogs, lizards, and other batrachians, possess true vocal organs. Among am- phibians the frog has a larynx provided with muscles, which produces a sound of varying pitch, dependent upon the strength of the muscular contraction and the force of the expiratory blast. The range of such vibrations is, however, extremely limited. In the Rana esculenta there is on each side of the angle of the mouth a membranous bag which may.
