siderably conj?estod. The liver was mucli congested, fatty, aud weighed 

 twenty-one pounds. 



The spleen was of a purple hue, its tissues undergoing disintegration, 

 and it weighed two and one-half pounds. 



Tlie kidneys were dark colored, and the bladder largely distended 

 with bloody urine. 



The spinal cord only of this animal was examined, and the gray mat- 

 ter found of a dark red color in the jiosterior part adjoining the cauda 

 equina. 



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

 Mr. Mathews, near Tolono. Examined three hours after death. ^Marked 

 cadaveric rigidity. Organs of resj^iration healthy. The heart, of nor- 

 mal 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 ecchy- 

 mosis. 



The mouth, pharynx, oesophagus, the first and the second stomach, 

 were healthy. The third stomacli 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 ecchy- 

 motic patches, which sloughed in their centers. In the pyloric end 

 were several irregular j)atches 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 i)artially afltected the ileum and large intestine. 

 The liver was normal in size and general aspect. 



The spleen was of a dark i)urple tint, about three times its natural 

 size, and its pulj) softened. 



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

 distended with bloody urine. 



Observation TV, August 1, 1808. — Seven-year-old steer; the property 

 of 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. Eespiratory pas- 

 sages healthy. On opening the chest it was noticed that the Inngs were 

 only partially collapsed. They had rather a blanched ai)pearance, 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-nuirked interlobular emphysema. Incisions in various ])arts of 

 the emphysematous tissue indicated the normal asi>ect of the lobules, 

 with free extravasation of air in the connective tissue around them. 

 The hiiigs weighed fifteen pounds. Tlie mediastinal reflections of the 

 pleura were densely studded with e(;chymoses, and the same appearance 

 I)ervaded the pleural portions of the same membrane. The pericardial
