    cords, which par excellence constitute the projections men- tioned ; the inferior cavity extends from the lower surface oi the vocal cords to the inferior aperture. By a cleft-like space between the vocal cords the two cavities intercommunicate. The walls of these cavities, especially those of the upper, are so important in every point of view that I feel bound to describe them somewhat in detail. The. front wall of the superior laryngeal cavity is formed by tlie posterior face of the epiglottis throughout its whole extent, and the portion above the attachment of the vocal cords of the entering angle of the thyroid cartilage. It descends as a gutter- • like groove between the anterior extremities of the ventricular folds to the limit of the vocal cords. This groove, which is called the central fossa of the larynx, is the posterior surface of the pomum Adami, and a very important point of insertion for the aryteno-thyroid ligaments, etc. Characteristic ulcerations of various origin, and abscesses are found, especially in the lower regions of this front wall, and I shall describe particularly the mode of reaching them. The more easily to designate the lateral walls of th^ superior cavity of tb^ larynx, I have adopted for each the name qua- drangular membrane. At their junction with the front wall the two form two grooves, which, running downwards, unite in the central fossa. These lateral walls contain the sacculi and ventricles. Each ventricle—also called ventricle of Mor- gagni, and sometimes entrance to the sacculus—is an oblong fossa, extending just above the vocal cords for nearly their whole length. It is bounded behind by a small semilunar fold near the attachment of each vocal cord; below by the upper surface of the latter, i.e. by tho lip of the glottis or lateral floor of the superior cavity; in front by a little fold, sometimes wedge-shaped, sometimes semilunar like the one behind, and above by an arched border of mucous membrane, called the ventricular band or fold. The ventricular bands are crescentic projecting folds of mucous membrane, commencing at the com- mencement of the central fossa, and extending with their con- cavity looking downwards to the little valvular fold which forms the posterior boundary of the ventricle, and which is indicated on the front surface of the arytenoid cartilage by a
