They may be inodorous, or children, the vomica; are less common than in adults. As thedisease advances, a false membrane forms around the decayingtubercle, at first thin and delicate, and in appearance resemblingmucous membrane. Large abscesses are sometimes seen, betweenwhich and the bronchi there is no Fig. 28. Cicatrization of Tuberculous Cavities.—Laennec proved in hisearly researches into the termination of tuberculous disease, that Fig. 28. The Beotion of the upper portion of lung in a case seen from -within, the apex having beenleft entire to show the deep puckerings which covered its surface. The line of the healed cavity isdensely loaded with black carbonaceous deposit, in which are seen five cretaceous concretions, threeof them encysted. This preparation is perhaps a unique specimen, proving the healing, by cicatri-zation, of an enormous tubercular excavation in the lung. 480 PHTHISIS. this condition is not of rare occurrence. Indeed, from this welearn that phthisis may terminate favorably when the deposit islimited in extent. But, sometimes at the apex of the lung, we find an old adhesion,or a crust of fibro-cartilaginous deposit, or even a fibrous
