![verted into a putrid deliquum; and from these, when cut into, there flows a turbid sanies of a greenish grey colour, and of an insupportable gangrenous fetor. The gangrenous affection occupies at least a great portion of one lobe, aud occasionally the greatest part of one lung: it has no definite boundary. In some places pulmonary sub- stance, altogether or nearly sound, blends insensibly with the gangrenous parts; in other instances these are separated by a portion of lung inflamed in the first degree, and in still rarer instances by a hepatized portion. If the disease is at all extensive, the progress of the symptoms is extremely rapid. The patient's strength is prostrate from the very beginning: the oppression becomes all at once extreme; the pulse is small, compressed, and frequent; the cough is rather fre- quent than strong; the expectoration is diffluent, of a very peculiar green colour, and exhaling an extreme fetor, pre- cisely similar to that of a sphacelated limb. This expecto- ration is copious for a time, but soon ceases through loss of power, and the patient dies sufibcated. b. Circumscribed gangrene. Partial gangrene may occur in any part of the lungs. It exists in three different states; that of recent mortification or gangrenous eschar, that of deliquescent sphacelus, and that of an excavation produced by the softening and evacuation of the sphacelated spot. When the sphacelated substance, of a dirty greenish-grey colour, occasionally bloody, and horribly fetid, separates and makes its way into the neighbouring bronchi, an ul- cerated excavation is left, which for a long time retains something of the gangrenous character. Sometimes the gangrenous eschar, in a state of decomposition, makes its way through the pleura, and excites a pleurisy, usually ac- companied by pneumothorax, either from the gas exhaled by the putrid eschar, or from a simultaneous communication with the bronchi. Gangrene occasionally takes place of the walls of a tu- berculous excavation. V. Pulmonary hemorrhage may arise from rupture or ul- ceration of a vessel [u. 69.], or from an aneurism bursting into the lungs [s. 73.]: but these accidents are rare; and](https://iiif.wellcomecollection.org/image/b21066735_0533.jp2/full/800%2C/0/default.jpg)
