30 Pathologic Anatomy and Histology. 



membrane is pale or whitish, often with petechiae and 

 oedema. Rigor mortis is not complete in most cases. 

 In the subcutaneous and intermuscular connective tissues 

 ecchymoses, haemorrhages, gelatinous or bloody infiltra- 

 tions are usually met with. In the blood vessels there is 

 either a small quantity of thin blood or nothing at all. 

 The muscles are as a rule soft, discolored and cloudy. 

 In the chronic cases no especial changes take place in the 

 muscles, excepting their general atrophy. The paniculus 

 adiposus is rather thick, compared to a high emaciation 

 of the cadaver. 



The abdominal fluid increases in almost all cases. 

 The peritoneum and mesentery have often ecchymoses of 

 various sizes and shapes. 



The stomach and intestine are always found full of 

 contents. No especial changes are seen in the alimentary 

 canal, excepting its catarrhic changes in a few cases. 



In the acute cases or after several febrile attacks 

 the spleen is ususally enlarged and sometimes becomes 

 twice or three times as large as the normal size. Its 

 capsule is distended, showing petechiae. The pulp be- 

 comes dark red giving an appearance of soft mud, and 

 reminding one of that of anthrax. In the chronic cases 

 the pulp increases both in volume and in hardness. Its 

 section surface is grayish with a tint of reddish brown. 

 But in the cases of slow progress such changes as splenic 

 tumor are not seen. 



The liver is in most cases enlarged accompanied 

 by such changes as hyperaemia, haemosiderin infiltration, 

 icterus, cloudy swelling, or fatty degeneration. Those 

 which died of, or were killed after, several attacks of 

 the disease, had the livers not only enlarged, but they 

 were also provided on their surface with small white 

 spots, powdery, net-like or cloud-like. These are situated
