[=Notice=: 1. While _in situ_—degree of collapse; adhesions; position and character of; wounds, etc. 2. _After removal_—external character; color; peculiarity of shape; adhesion of lobes; puckerings at apex; solid or compressible; crepitation; where most noticeable; effect of inflation on color and size. _Tubercular deposits_—size; location. 3. _Substance of lung_—solid or porous when cut; extent of solidified portions; fluids escaping; character and quantity of. _Abscesses_—position; number; size; character of contents; color; odor, etc.; condition of lung around cavities; character of walls; thick or thin; smooth or rough; crossed by bands; communication with bronchial tubes. _Gangrene_—location and extent of. _Bronchial tubes_—contents; contraction or dilatation; measurements at, above and below these points; condition of mucous membrane; congested or ulcerated; walls of tubes; thicker or thinner than natural. _Extravasation of blood_—(apoplexy of lung;) portion and extent of lung involved; condition of surrounding tissue; blood infiltrated or encysted. _Adventitious deposits—cretaceous bodies_; situation; size; density; condition of surrounding tissues. _Tubercles_—seat; size; number; color; density, etc.; condition of surrounding tissue. _Cancerous masses_—size; location, etc. _Carbonaceous deposits_—around bronchial tubes; beneath pleura. _Result of placing entire lungs in water_—do they sink or float? If they sink, is it rapidly or slowly? If they float, is it above, below, or at the surface of the water? Results with portions of each lung.] The pathological conditions of the lungs, may be arranged as follows:—_Inflammation_ and its results, _hepatization_, _suppuration_, _abscess_, _gangrene_, _hæmorrhage_, _pulmonary apoplexy_, _emphysema_, _tubercular disease_, _morbid growths_, and _parasitical animals_. When in a healthy condition, the lungs will present the following appearance:—Upon opening the chest, there will be a more or less complete collapse of both organs, partly from atmospheric pressure, and partly from the elasticity of the lung tissue. They will then have a shrunken, shrivelled appearance, crepitating under pressure, and have an ashen gray color. If inflated, the surface becomes smooth and shining, showing an indistinct outline of the lobules, which, with the dark pigmentary matter seen here and there, gives the surface more or less of a mottled appearance. Where pleurisy had previously existed, there may be adhesions preventing the collapse of the lungs, until these have been broken up. When cut into, healthy lung tissue has a soft, spongy character, the upper portions will be quite destitute of blood, while the posterior portions may be more or less filled with that fluid from gravitation, giving them a dark congested appearance.
