 healthy. The cardiac end of the fourth stomach was of a deep red color, 

 some of the folds ecchymosed, and some of the dark centers of the ec- 

 chymoses had sloughed. The pyloric end was much less congested, 

 but its entire surface more or less abraded. 



The exposed vascular membrane was of a dark red color, and the food

With the exception of slight ecchymoses of the pleura on the anterior 

 lobe of the left lung, the organs of respiration offered no indications of 

 disease.

 tricle. 



The organs of deglutition, the first, the second, and the third stom- 

 ach, were quite healthy. The fourth stomach not quite so much con-

 ecchymoses, many of which were perforated in their centers. The pylo- 

 ric end was also somewhat congested, but the erosions were more marked 

 and extensive than on the transverse folds of the cardiac end. Xear 

 the i)yloric opening were several small ulcers, to the surface of M4iich 

 the gastric contents had adhered.
