    The appearance is that of fine froth or spumous saliva under the pleura. Vesicular emphysema presents an exaggeration of this appear- ance. It is delineated in Fig. 35. The vesicles (represented, in a single lobule, a, by black lines, their white parietes being too delicate to admit of imitation) are larger and less uniform in size than in the healthy lung, equalling, and sometimes exceeding, pins’ heads of various magnitudes. The interlobular partitions are rendered beautifully distinct inthis specimen by the remarkable quantity of black pulmonary matter accumulated along them, the effect of which is further increased by the paleness of the lung, consequent on its emphysematous inflation, by which the blood is expelled. This distinctness serves to show more clearly that the lobules, by inflation, lose somewhat of their angular form and become more rounded. At the same time they bulge a little externally, so as to render the surface of the pleura hilly. These characters, namely, the pale- ness, the roundness, and the bulging, existing either in scattered lobules or in an assemblage of them, are the criteria by which even slight emphysema may be recognized more easily at a glance than by any other physical appearances. The same exsanguine character is seen in Fig. 9, b, and c; in Fig. 24, below d, where, however, there is still a light-red tinge; and in Figs. 36 and 38. The vesicles may be enlarged to the size represented in Fig. 35, a, without rupture of their parietes; but when they exceed this size, it is generally in consequence of the rupture taking place, by which several vesicles are thrown together. Under these circumstances they may attain the size of peas or cherry-stones. Sometimes the vesicles of a whole lobule unite and form a single large cell; and, in extreme cases, even the lobular septa themselves give way, and several lobules, thrown together, form a spacious cavity, which is usually traversed by a few straggling web-like filaments of cellular tissue. This is beautifully exhibited in a dried specimen before me. Sometimes, though rarely, enlarged vesicles project beyond the
