It may be-come confluent and produce pseudo-lobarcaseous pneumonia. Then it takes on a fanshape. It is probably caused by aspiratingdroplets of sputum containing large numbers I A-Ray Examination of the Chest 437 of virulent tubercle bacilli into primary lob-ules. The size of these densities varies greatlyeven in the same individual, but to a greaterextent in different individuals. Sometimesthey are so small as to suggest miliary lesionsand again they appear as a filbert. When the .r-ray picture is hazy and the more extensive the lesion the more gravethe prognosis. Caseous bronchopneumoniamust be differentiated from acute broncho-pneumonia. The latter lesions are usuallymuch less dense and they are not associatedwith large apical lesions. Also the cases ofcaseous pleurisy found in the puerile classifi-cation have similar lung- densities without

Thus, when we see the pictureof finely mottled caseous bronchopneumoniaas through a snowstorm, we may suspectthat we have gelatinous tuberculous broncho-pneumonia or caseous bronchopneumoniacomplicated with an acute pneumonia. Case-ous tuberculous bronchopneumonia may ex-ist over a large area without causing anysigns or symptoms, but always suggests agrave prognosis. The more acute and the apical lesions.

Always we have the clini-cal picture, the history and physical signs tohelp to solve these knotty problems, and theroentgenologist has only to desc
