49 6 History of Animal Plagues. 



jToro-ed with blood, of a livid colour, and often sphacelous. On 

 being cnt into, a puriform matter, similar to that which filled the 

 trachea and flowed from the mouth, exuded. The bronchial 

 glands, like the axillary, the inguinal, and the mesenteric, were 

 infiltrated. 7. The pleurae participated, in many cases, in the in- 

 flammatory state, 8. The epiploon [omentum) showed oftentimes 

 patches of inflammation and gangrene. 9. The rumen was very 

 much distended by an enormous mass of food, which we have fre- 

 quently found hot and as if fermenting. In nearly all the sub- 

 jects, the lining membrane of this viscus was detached, and 

 covered the alimentary matters in the form of a brown pellicle, 

 which was without consistence and easily torn.^ The reticulum 

 was often in the same state; the lining membrane which covers its 

 meshes was sphacelous, and could be removed at the slightest 

 touch. The third compartment [feidllet) was gorged with dry 

 food; in some cases this was excessively hard, and in many parts of 

 the viscus we perceived, on examining it closely, that the dryness 

 was very considerable. The internal membrane was separated 

 and remained attached to the food, where it appeared brown, like 

 bronze. The leaves of this division were also very soft and easily 

 torn ; but the hardness of this organ was not always the same. 

 The fourth compartment [caillette) was always very inflamed ; 

 many of its plicatures were livid; that portion which was nearest 

 the pylorus was the most aff'ected, and was not unfrequently 

 swollen and looking as if ulcerated. This cavity was filled with 

 . a very fetid greenish fluid. 10. The inflammation reached its 

 highest degree in the small intestines ; the blood-vessels were 

 gorged with blood, and the intestines themselves were filled with 

 a putrid matter and mucus concretions which covered their walls, 

 while the lining membrane itself was in a very unhealthy state. 

 The inflammation was less severe in the large intestines, where 

 the mucosities, however, were in greater abundance. We have 

 once found the rectum excoriated in many places, and covered 

 with a glutinous white substance like pus. ii. The gall-bladder 

 was very distended; on opening it bile of a dark-green or yellow 

 colour escaped, which in some cases had the consistency of olive 

 oil ; there always remained in this viscus a considerable sedi- 



^ This is a normal condition.
