It isin the early stages of these cases of unilateral infiltration that diagnosisis difficult. An aid to diagnosis is the condition of the epiglottis, inwhich the infiltration is deposited along its crescentic edge, giving it aturban-shape. Ulcerations may now appear, starting as minute points, but graduallycoalescing and finally covering extensive areas. The tubercular ulcerdoes not markedly differ in color from surrounding areas of infiltration ;its surface is slightly uneven. Unless the process has invaded the epiglot-tis and true cords, the loss of substance does not appear very noticeable,but if such invasion takes place the tissues seem gradually to disappear. TUBERCULOSIS OF THE LARYNX. 633 by a slow melting away. Finally, if any of the cartilages become necrosedand exfoliated, there occur varying conditions of distortion of the partsoccasioned by their loss. Prognosis.—This is, of course, always unfavorable, but cases of re-covery from the local lesion have been reported. This is one of the morehopeful features of the progress in therapy during the last few years, forphysicians have learned that much may be effected by energetic inter-vention, and they no longer content themselves with merely palliativeroutine measures. Cohen estimates his own recoveries as one per cent,of the total number of cases seen by him. Eecovery in this sense refersto the ability to resume occupation and to live for a varying num-ber of years, or, as stated by Delavan, ^ to call that case cured in whichall trace of active disease has disappeared from the larynx and all ac-tive symptoms referable to that organ
