Theentire lung is practically replaced byfibrous tissue showing a dense irregularshadow. The condition produced is knownpathologically as chronic interstitial pneu-monia. Some modification of this process isprobably what has been referred to asunresolved pneumonia. The last complication of pneumonia towhich I desire to call attention is lungabscess.

Note the peripheral location of theshadow, and that when associated with plasticpleurisy, localized collections of fluid are not sharplyoutlined. Organization takes place, and finally scartissue is formed. The lung tissue maybecome involved and an interstitial fibrosis,similar in character, may result, either froman extension of the process, or as a result offunctionless condition produced in thelung. The ultimate stage of the process is acontraction of the scar tissue. The heartand mediastinal structures are drawn overtoward the affected side. The diaphragmis elevated and the intercostal spaces arenarrowed. The entire side of the chestbecomes more shallow than the normalside, a condition which is even more Fi<;. 12.
