DISEASES OF SWINE AND OTHER ANIMALS. 395 
and even the seat of microscopic extravasations of blood, while in some cases the 
black necrotic cuticle is coyered by a dried crust of exuded lymph of a dark brown 
color. 
The right ear is of a deep purple color, and purple patches of various sizes are found 
inside forearms and thighs, onthe hocks, and beneath the chest. In these purple patches 
the true skin is the seat of extensive congestion with stagnation and coagulation of 
the blood in many of the capillaries, and numerous microscopic clots of extravasated 
blood, while all the tissues are stained with hzematine. 
Blood: That from the jugular is yery dark and forms slowly a soft diffluent clot; 
red globules round and large. That from the carotid is crimson, and clots quickly and 
ae red globules crenate, small and shrunken. Blood from both vessels is slightly 
alkaline. 
Tongue: On the posterior third of the right border is a purple spot one-half line in 
diameter, which cannot be effaced by pressure. Under the microscope this shows the 
same congestion and microscopic extrayasations with the spots on the skin. The 
conical papillx on the upper surface of the organ near its base have their tips of a 
very deep purplish red. 
Larynx: There is purple punctiform discoloration on the posterior surface of the 
epiglottis, which cannot be removed by pressure. } 
Lymphatic glands: Those around the throat are deeply stained with blood, some only 
superficially and some throughout, This is true also of the glands of the chest, groin, 
and abdomen, but especially of the mesentery. In several cases the glands appear to 
beenlarged. Microscopically, they present congested capillaries filled with coagulated 
blood, minute extravasations, and a profusion of granules and granular cells. 
Abdomen—parasites in peritoneum: Two hydatids were found respectively in the omen- 
tum and mesentery. 
Stomach: Well filled; great curvature of a deep dark red; contents strongly acid. 
Small intestine: Congested in some parts, but with no observed extravasation nor 
deep discoloration; contents not abundant, but at intervals stained of a deep biliary 
yellow, and with excess of mucus throughout. 
: meonea valve: With Peyer’s follicles dilated, and contents in some slightly yel- 
owish. 
Cecum: Close to the ilio-cecal valve a considerable erosion, with raised center and 
margin, but no excess of vascularity. 
Colon: Six inches from the cecum is a sloughing ulcer, one and one-half lines in 
diameter, raised above the adjacent membraue, the superficial layers being of a dirty 
white color in the center, and non-vaseular, while around the margin of the ulcer is 
no marked redness. , 
Liver, colon, and rectum: Several extravasation patches averaging one line in diam- 
eter, bright red, and evidently quite recent. 
No intestinal parasites. ; 
Liver: Firm; solid; considerable portions are of a deep purple hue, the deep color- 
ation being mostly confined to the center of the acini. 
Kidneys: Cortical portion soft and of a very light brown, almost parboiled, appear-: 
ance. Papille and medullary parts of a very deep red. 
Muscles: Contained no parasites. 
Srain: Normal,
