Physical examination shoued coarse moist ralesat both bases, and dullness and diminished breathsounds at the right base. The plate has the generalhazy appearance characteristic of cardiac pneumo-fibrosis, with the marked increase in the hilus shadowsand general thickening along the course of the bronchi.The unusual appearance in this case is the areas ofsharply defined increased density in the right chestand the high flat diaphragm on the right side. Thiscould be interpreted as being due to changes in thepleura. lobule is greatly increased in bulk, andthe alveolar walls in extreme cases becomethickened and indurated by the appearanceof new connectI\e tissue (brown indurationof the lungs). The extent of change from the normalas seen with the .x-rays varies widely,depending upon the severity and durationof the disease. Early changes are seen atthe hilus, and as the process pr
