74 SEPTICAEMIA HEMORRHAGICA 



from evidence of disease. A few showed a small number of 

 hemorrhagic areas, pyramidal in shape with their bases on the 

 pleura. In most cases the parietal pleura is studded with 

 small hemorrhages. The diaphragm sometimes contains ver_v 

 large hemorrhagic areas. 



The pericardial sac usualh' shows small, sometimes very 

 numerous hemorrhages in the walls, and in man\' instances 

 contains a blood stained serum. 



The heart walls, with but few exceptions, contain large 

 and small hemorrhages. These sometimes extend deep into 

 the muscle. Similar areas of hemorrhage are also visible in the 

 endocardium. The heart contains blood clots, post-mortem in 

 formation. 



The blood, in animals just dead, is somewhat lighter than 

 normal in color. When post-mortem changes set in, the blood 

 is darker in color, but reddens on exposure to the air. 



The spleen shows on its surface a few small hemorrhagic 

 areas. It is usually normal in size, color and consistency, 

 except where post-mortem changes have taken place. 



Stomatitis and glossitis are rarely observed. The pharynx 

 is usually congested. 



The stomach walls contain few or many hemorrhagic 

 areas. These are sometimes extremely large, especiallj' on 

 the third stomach. As a rule the larger hemorrhages penetrate 

 the entire thickness of the walls. The smaller ones are con- 

 fined to the subserous or mucous coats. The stomach contents 

 are apparently normal. 



The intestinal walls are constantly affected. Hemorrhagic 

 areas involving all the coats are frequently present. Smaller 

 ones, visible only from the inner or outer surface, are always 

 present. General enteritis and peritonitis are occasionally ob- 

 served. Localized enteritis is frequent. 



The bowel contents are in some cases dark and tarry ; in 

 others the feces are apparently normal in color and consistency 

 but streaked with bloody mucus. 



The kidneys are usually but slightly affected. When le- 

 sions are present they are but pin point in size and mostly 

 confined to the cortical substance, though a few are found in
