    A woman, 63 years old, has been hoarse for some time. The voice is feeble, rough, and toneless. The only abnormality in the larynx is observed during phona- tion, which presents the following curious picture. The edges of the vocal cords present in the resting position, as usual, a smooth, slightly concave outline; but as soon as the glottis is closed the edges become wavy, so that closure is not complete. A sound can he introduced without causing the patient to cough ; in fact, she does not feel it when she closes her eyes. Even the linger elicits no reflex either from the epiglottis or from the superior aperture of the larynx. If the ringer is held on the cricothyroid ligament during phonation, no tension or movement of the two arytenoid cartilages can be felt. We, therefore, have to deal with paralysis of the cricothyroid muscle and of the sensory nerves of the larynx. As these constitute the entire domain of the superior laryngeal nerves, we have before us a Paralysis of the Superior Laryngeal Nerves. As no other abnormal condition can be found in the body, it is im- possible to determine the cause.
