    Stuttering, on the other hand, is a vicious utter- ance, manifested by frequent repetitions of initial or other elementary sounds, and always more or less attended with muscular contortions. Having thus concisely stated the distinctive marks of each disorder,* I proceed to consider them in their individual characters. a manner, that it was quite distressing to hear her.

The pro- duction of speech is effected by the conjoint agency of the respi- ratory, vocal, and articulating organs. The muscles of the ab- domen, of the diaphragm, the thorax, the larynx, the pharynx, the tongue, and the face have all their functions necessary for the production of speech; but unless they act in harmony, there can be no right production of articulate language. The function of respiration may be carried on independent of articulation; but voice and speech cannot be produced without the action of the respiratory organs. The respiratory apparatus includes the lungs, the trachea (windpipe), the ribs, and all the muscles connected with them, the diaphragm, and the abdominal muscles. The production of the voice takes place in the larynx—a car- tilaginous case situated at the anterior part of the neck on the top of the windpipe, with which it is connected by membranes and ligaments.
