Again, the tongue, like the nostrils, has also been reduced to a mere vestio-e. Stranger still is the fact that immediately under the skin there lies an extensive system of air- cells of large size, which can be inflated or emptied at will. Many of these cells dip down between the muscles of the body, so that the whole organism is pervaded with air-cells, all of which are in connection with the lungs.
