Plate IV. 



Miliary Tuberculosis (Acute) of the Lung. 

 The miliary tubercles, small and irregular in shape, are distributed 



throughout the lung more abundantly in the upper and middle thirds. 

 The blood-vessels are injected with blue gelatin, so that in this 



photographic reproduction of the specimen the uninvolved portions of 



the lung are dark, while the tubercles in which the blood-vessels are 



compressed or obliterated are light.
