AND SINGULAR CONGESTION OF THE LUNGS. 731 
nostrils. The breathing, which had been tolerably, quiet from the 
commencement, is now very laborious. The extremities are cold, 
and there is every appearance of approaching death. Small doses 
of chloride of lime were administered, but she died in the evening. 
On opening the chest, a considerable quantity of serous fluid 
escaped, as it did also from the pericardium, and there was some 
likewise in the cavity of the chest. 
The right lung presented a black, disorganized mass. The 
lining membrane, and even the rings of the bronchial tubes, were 
partly decomposed. The left lung and its bronchi exhibited very 
slight traces of disease. This accounted for the comparative steadi- 
ness of breathing which had continued until the last day. The 
bronchial tubes on the right side had, from the position of the 
mare, received all the blood that flowed into the trachea. 
The cesophagean canal was next laid open from the pharynx to 
the stomach. It was perfect in all its parts, and did not indicate the 
smallest trace of inflammation either on its cuticular or muscular 
tunic. 
You may suppose that I am not a little annoyed by this fatal 
termination of the case. Was there any thing wrong in my method 
of proceeding] 
[Not at all. The removal of the impacted bran was a case of ab- 
solute necessity, and, agglutinated together as it was, very consi- 
derable force was requisite. That force could be more readily 
and safely applied when she was cast than during the partial 
confinement of the head, which could otherwise be effected. 
The abrasion produced by the probang was probably in the 
back part of the mouth, where it would be compelled to 
take a curved direction. It could not have been perceived until 
the instrument was withdrawn, and ere that was quite effected 
some blood had passed down the trachea and entered the right 
bronchi. The mare exhibited symptoms of suffocation ; a por- 
tion, but not the whole, of the blood was returned, or some lesion 
of the mucous membrane of the bronchi was effected in the 
struggle to return it: congestion of the membrane very soon 
followed, and a mechanical obstacle presented itself to the free re- 
turn of the blood to the left side of the heart. These congestions 
are sometimes connected with apparently trifling causes, and the 
supposed diagnostic symptoms of them are not always present.
