involved. It may be quite localised to one lobe, or may involve thewhole of one lung, while the other lung may show signs of congestion. It maybe accompanied by a pleural effusion. The clinical history and the feverishstate of the patient should give a clue to the nature of the disease, and thesubsequent resolution of the inflammatory process, with the slow subsidenceof the shadow seen on radiographic examination, will help to clear up thediagnosis. An acute pneumonia may, however, not resolve quickly, anda shadow in the substance of the lung may be visible for several weeks afterthe inflammatory symptoms have subsided. Later on the affected portionof lung may become fibrosed. It is this class of case which gives rise togreat difficulty in radiographic diagnosis. Acute broncho-pneumonia, whenoccurring in children, is another condition which leads to great difficulty indiagnosis, especially as an acute mihary tuberculosis gives nearly the sameappearances on radiographic investigation.

DISEASES OF THE PLEURA 297 Interstitial Pneumonia.—The forms of interstitial pneumonia whichresult in an increase of the fibrous tissue of the bronchi and lungs may alsogive rise to difficulties of diagnosis. The most commonly met with are :(1) Those following an acute pneumonia ; (2) those due to inhalation of dust ;(3) those due to the chronic action of bacterial poisons, e.g. tuberculosis,syphilis, actinomycosis. Pneumonokoniosis.—Interstitial pneumonia due to the inhalation ofdust. There are three varieties of this according to the type of dust inhaled :(1) Anthracosis, coal-miners lung ; (2) silicosis, stone-masons lung ; (3)siderosis, needle-grinders lung. In all these forms the foreign particlesare inhaled and absorbed by the lymphocytes. They are deposited alongthe course of the lymphatics, forming nodules, and tending by chronic irrita-tion to a marked degree of fibrosis. The
