end of tlio fourth stoinach was intensely reddened, and its folds marked 

 by zi<;zn<; lissuresor ulcteratious, in the center of which were black scabs, 

 with adherent food. The])yloricend was of more normal color, but four 

 ulcers, about one-half inch broad, and of irregular shape, existed in its 

 jniddle; and at the pyloric end was a larger spot of idceration, about 

 one inch in length. 



The duodenum was much congested on its minor surface, and diffuse 

 redness pervaded the mucous membrane of the jejunum and ileum. In 

 various parts of the latter were snmll, dark petechiie. 



The mucous membrane of the whole of the large intestine was of a 

 dark red color, and the excrement in the rectum was tinged with blood. 

 Through the whole of the longitudrnal mucous folds extravasations of 

 blood had occurred. The liver and gall bladder weighed seventeen and 

 one-half pounds, and ai)peared healthy. The bile in the gall bladder 

 was thick. The spleen was very dark in color, its pulp soft, and general 

 weight live and one-half pounds. 



The kidneys were much congested, and the mucous membrane of each 

 pelvis spotted with dark ecchymoses. 



In the peritoneal cul de sac, around the bladder and rectum, were 

 numerous bright ecchymoses. The bladder was full of bloody urine, 

 and its mucous lining extensively dotted with small blood spots, of a 

 vermilion hue. 



On severing the head from the neck, a large quantity of serum flowed 

 from the meninges. The meninges were dark, and of the general color 

 of the gray matter of the cord, and the brain was much redder than in 

 health. 



Observation XX, September 5, 18GS. — Three-year-old red-and-white

 had died during the preceding night, and was dissected at 3 p. m. on 

 the 5th. There was no sign of decomposition, and the internal organs 

 were still warm. 



The organs of respiration were healthy. 



Heart and pericardium sound, and free from ecchymoses. 



Organs of deglutition and iirst stomach healthy. Secoiul stomach of a 

 dull red hue in its inner lining. Third stomach normal. Fourth stom- 

 ach of a dark red color at its cardiac end, with various ecchymoses, and 

 half a dozen small, circumscribed spots where the e])ithelium had been 

 thrown oH", and the dark red vas<;ular membrane exposed. 



The general color of the lining in the antrum i)yhn'i, was much less 

 intensely red than in the transverse folds, but was the seat of several 

 erosions. 



The pyloric gland had a zigzag ulcer on its summit. 



The small intestine was the seat of ramihed redness. In the large 

 intestine the longitudinal mucous folds were all reddened along their 

 free margins, by blood extravasation. 



The liver was sound, but the gall bladder thickened by serous iufiltra-
