the uigbt ; and, as tlie post mortem indicated, from liemorrliage from the 



spleen. 



Observation VII, August 7, 18G8.— Steer; the property of Mr. P.Har- 

 ris, of Champaign. Organs of respiration healthy. General aspect of 

 heart normal. Right cavities containing a little blood, and free from 

 ecchymoses On the fleshy pillars of the left ventricle there was marked 

 and diflused extravasations of blood. The anterior part of the ali- 

 mentary canal, as far down as the third stomach, was quite normal. 

 The fourth stomach was slightly reddened ; and, at the cardiac end, the 

 folds were studded with small, yellowish eminences, as described in a 

 previous case. The pyloric end was the seat of marked and numerous 

 erosions. The intestinal tract was quite healthy, with the exception of 

 slight redness of the nnicous surface of the small intestine. 

 The liver and gall bladder were nornml. 



The spleen was at least twice its natiual size, of a dark color, and soft- 

 ened structure. 



The kidneys were dark-colored from congestion, and the bladder very 

 much distended with urine of port- wine color. 



On severing the head from the neck, it was found that around the 

 dura nniter, in the foramen magnum, there was an exudation of yellowish 

 lymph, studded with numerous confluent petechia of a very dark color. 

 On removing the brain it was found of normal consistence. The spinal 

 cord in the dorsal and the lumbar region was reddened, especially in the 

 upper horns of its gray matter. 



Observation VIII, August 7, 1SG8.— Steer; also the property of Mr. . 

 P. Harris, of Champaign. Killed for the purpose of dissection. Organs 

 of respiration healthy throughout. Heart slightly ecchyrnosed on the 

 outer surface of the ventricles. The right side contained a small quan-

 ventricular valves. Left ventricle empty and healthy. 



Pharynx, gullet, the first and the second stomach, healthy. The third 

 stomach impacted with dry food. The fourth stomach of a deep red 

 color over its cardiac folds, and studded somewhat with small, grayish 

 eminences of the size of ordinary pins' heads. The mucous surface of 

 the pyloric end, wherever it was whole, was of normal color; but it was 

 freely spotted with very distinct erosions of irregvdar shape, dark in 

 the center; and the largest of these was on the pyloric gland and 

 extending on the transverse fold at the pyloric -opening. The duode- 

 num, and indeed the entire small intestine, was found with the mucous 

 surface congested. The ctecum, colon and rectum, throughout their 

 entire length, were reddened within, and ecchymoses were freely dis- 

 tributed over their whole interior. The liver and gall bladder were 

 normal. 



The si)loen was dark colored, soft, and thrice its natural size. The 

 kidneys were somewhat congested, and the urinary bladder, though
