ALL animals with lungs have some sort of contrivance in the windpipe that is able to set the air in vibration as it is expelled or inhaled. Some have not only this means of making vocal sound, but have also power to vary the quality and intensity of it. Out of this second ability come speech and song.
Ants converse with their antennae, having no lungs nor windpipe.
Bees do the same. Those of her attendants who first perceive the absence of the queen from the hive apply their antennae to the feelers of their companions. The ensuing excitement settles the question as to their ability to talk. This shows that while voice is the usual organ of language there is yet a good deal of conversation going on about us that is not expressed in words, just as there is much music performed by insect orchestras with no vocal contributions. Hares and Rabbits never use their voices except when suffering intensely.
