Excerpt from The Teeth: Natural and Artificial The mouth - the organ of speech and mas tication - is not only the most expressive and characteristic, but also the most im portant, of all the features. It is connected by means of its lining mucous membrane witlbthe pharynx, esophagus, stomach, and intestinal canal, and with the lary nx, trachea, and bronchi being thus vitally related to the economy of respiration and digestion. This close relationship and sym pathy of the parts are manifested in disease by perceptible changes in the tongue, gums, lips, and mucous membranes while through the nerves, with which the mouth is so abundantly supplied, sympathetic relations are established with the eyes, ears, and, in fact, with every part of the body.
