by l)l()o(ly miiu'. The mucous surface of the bladder was studded all 

 over with small i)ete('hije of a vermilion hue, as seen in other cases. 



Observation XVI, August L*(), 180S. — lied steer: at slaughter-house, in 

 Bri(lge])()rt. 



Organs of resi)iration healthy. 



Heart tirm and of normal size, was slightly ecchymosed at the apex, 

 aud on tlic fleshy pillars of the left ventricle. Organs of deglutition 

 and the tirst stomach sound. The fourth stomach was slightly riMldencd 

 at the cardiac end; two small erosions, about one-third of an inch in 

 length, existed uear the pylorus, where the membrane generally was of 

 normal color. 

 / The intestines were healthy. 



The liver aud gall bladder, to all appearance, normal. 



The spleen, of a dark color, weighed four and a half pounds ; but its 

 structure had undergone little change, was firm, and of a brighter red 

 than any previously examined in splenic fever. The appearance of this 

 spleen is shown in plate. 



The kidneys were slightly congested, and, on cutting into the pelves, 

 SJine bright ecehymoses were found, as if in the earliest stage of blood 

 exbravascition in these structures. The bladder contained a moderate 

 quantity of clear-colored urine, but was slightly ecchymosed uear its 

 ueck. The cerebrospinal centers healthy. 



Observation XVII, August 21, 18G8. — Eed cow; examined at St. 

 Louis. Killed by effusiou of blood. Eespiratory passages heal th3^ On 

 opening the thorax the lungs were found pale, and only partially col- 

 lapsed. 



The posterior lobe of the right lung was the seat of extensive inter- 

 lobular emphysema. On the anterior aud the middle lobes were several 

 scattered patches of congestion, corresponding to congested lobules, 

 within which were simple reddened, not solidified, globules, and they 

 floated on water. 



The heart, of normal size and consistence, was slightly ecchymosed 

 on the anterior aud the posterior ventricalar furrows. Internally the 

 right cavities, containing a little fluid blood, were healthy; but the left 

 was tinged by ecchymotic spots on the fleshy pillars of ventricle. 



The mouth, pharynx, gullet, and first three stomachs, were healthy. 

 The fourth stomach was reddened at its cardiac end, and its folds stud- 

 ded all over with ecchymoses. This condition Avas kindly and most 

 accurately reproduced in a water-color sketch, by C. V. liiley, esq., State 

 entomologist. 



The small intestine was the seat of ramified redness throughout. In 

 the ciccum, in a line with the nuiscous folds, the blood extravasations 

 which had occurred were of a dark rusty color; and similar changes 

 were seen in the rectum. 



The liver and gall bladder, much congested, weighed twenty-five 

 pounds. In the liver were old atlhesions, and some deposits of yellow
