generally congested, and the posterior part of the cord, when cut across, indicated very 

 decided redness of the superior cornua of gray matter. 



Observation II, July 30, 1868. Cow; the property of Mr. 0. B. Chamberlain, of 

 Tolono. This animal was also bled to death and skinned. The thoracic organs were found 

 quite healthy. The first and the second stomach were likewise normal, but the third was 

 somewhat inordinately distended by dry food firmly impacted between its folds. The 

 folds themselves were sound. The fourth stomach was congested throughout, but its folds, 

 at the cardiac end&quot;, were of a deep, modena-red hue. In the vicinity of the pylorus were 

 a couple of small patches of erosions of the mucous membrane. The small intestine was 

 the seat of ramified redness throughout its entire length. In the large intestine, from the 

 caecum to the rectum, there was a dark, inky-looking deposit of blood along the free edge 

 of the mucous folds, and between these, at points, the membrane was considerably con 

 gested. The liver was much congested, fatty, and weighed twenty-one pounds. The 

 spleen was of a purple hue, its tissues undergoing disintegration, and it weighed two and 

 one-half pounds. The kidneys were dark colored, and the bladder largely distended with 

 bloody urine. The spinal cord only of this animal was examined, and the gray matter 

 found of a dark red color in the posterior part adjoining the cauda equina. 



Observation III, July 31, 1868. Two-year-old steer; the property of Mr. Matthews, 

 near Tolono. Examined three hours after death. Marked cadaveric rigidity. Organs 

 of respiration healthy. The heart, of normal size and firmness, was extensively ecchymosed 

 on its outer surface, especially down the anterior and the posterior ventricular furrows. 

 The right cavities contained a small amount of blood; the left were empty, but the fleshy 

 pillars were of a deep purplish tint from extensive ecchymosis. The mouth, pharynx, 

 oesophagus, the first and the second stomach, were healthy. The third stomach was 

 considerably distended by dry food. The fourth stomach was the seat of diffuse redness 

 over its entire mucous surface, but the depth of color was greatest at the cardiac end. 

 Freely dispersed over the surface were small, circumscribed erosions with red areolse round 

 them ; and these evidently resulted from ecchymotic patches, which sloughed in their cen 

 ters. In the pyloric end were several irregular patches of cuticular degenerations. The 

 green contents of the stomach adhered to the denuded surfaces. The jejunum was the 

 seat of ramified redness over its mucous surface, and a similar congestion partially affected 

 the ileum and large intestine. The liver was normal in size and general aspect. The 

 spleen was of a dark purple tint, about three times its natural size, and its pulp softened. 

 The kidneys were turgid with blood, and the urinary bladder was much distended with 

 bloody urine. 



Observation IV, August 1, 1868. Seven-year-old steer; the property of Mr L. D. 

 Ayers, of Farina. This animal was first seen ill on Thursday, the 30th of July, and died at 

 noon on the 1st of August. Respiratory passages healthy. On opening the chest it was 

 noticed that the lungs were only partially collapsed. They had rather a blanched appear 

 ance, and, on removal from the chest, it was found that through the posterior lobes, and 

 all along the upper aspect to the anterior lobes of the lungs, there was well-marked inter- 

 lobular emphysema. Incisions in various parts of the emphysematous tissue presented 

 the normal aspect, of the lobules, with free extravasation of air in the connective tissue 

 around them. The lungs weighed fifteen pounds. The mediastinal reflections of the 

 pleura were closely studded with ecchymoses, and the same appearance pervaded the
