Chronic phthisis nearly always begins at the apex of the lung,the exceptions to this rule being found chiefly in children. If wehappen to light upon a lung in an early stage of the disease wefind a larger or smaller portion of the apex consolidated, the solidtissue usually yellow, dry, and somewhat caseous, like the wholelung or larger masses in the catarrhal phthisis referred to justnow. Era. The apex of a lung affected with caseous pneumonia; the limitation of the disease was defined by a sharp line. The affected portion is sometimes separated by a sharp line fromthe healthy lung, sometimes a border of broncho-pneumonicgranulations is seen. There is not necessarily any miliary tubercle.
