    Chapter III. ABSCESS OF THE LUNGS. Pus deposited from pneumonitis, in the pulmonary substance and forming a real abscess, is extremely rare. Laennec met with only five or six instances of it in twenty years. The ab- scesses were small, not numerous, and were scattered through lungs in the third degree of inflammation. The walls were formed of pulmonary substance infiltrated with pus and in a state of putrilaginous softening, which increased progressively towards the centre of the abscess. This description applies to a small abscess in Fig. 4, opposite to d. In a new-born infant at the Hopital des Enfans-Trouves, were found numerous large abscesses scattered throughout the lung, and totally dis- similar from tuberculous excavations. The cause assigned by Laennec for the rarity of abscess from pneumonitis is, that in limited inflammation the patient recovers, and in extensive, he dies, before the pus has broken up the cellular tissue and resolved itself into an abscess. Accidental pressure with the fingers sometimes gives the appearance of an abscess, which in reality does not exist. Abscess after great Surgical Operations.—This is much more common than abscess from pneumonitis. I have seen it in seven or eight cases. It presents itself in the form of de- positions of various sizes in isolated points of healthy lung. It is exemplified in Fig. 11, taken from a case of amputation by Mr. Keate, which was followed by suppuration of the small veins of the stump. The part represented is a portion of the margin of the inferior lobe. The pleura is inflamed and coated with lymph, «, but the parenchyma, g, is sound, except amongst the depositions, e, where it is slightly indura- ted. The depositions are in progressive grades. The earliest, /, present a bluish, semi-transparent appearance, resembling cartilage, and feel like small, hardish granules, though they admit of being broken up by moderate pressure. In the next
