VETERINARY JURISPRUDENCE. 
and ten o’clock that night. I am sure that he ought then to have been bledw 
He had been getting worse rapidly from four o’clock till ten, I sat up with 
him myself till almost three o’clock the next morning, and I was quite certain 
then that his lungs were diseased. His breathing was not very much disturbed. 
The horse was very ill, and it was quite plain to me that there was also some 
inflammation of the mucous membrane of the bowels. I sat up with him 
almost all night, but he was much worse in the morning. He had his medi¬ 
cine repeated, and warm water to drink, which, in my judgment, were the most 
proper remedies. He continued to grow worse, and died on the 12th, at about 
six o’clock in the morning. He was not bled again after the night of the 8th. 
I saw that the last bleeding had done him no good, and I did not repeat it. 
He continued to grow worse from the time he was first taken ill until he died. 
I saw him repeatedly during the 10th and 11th, at different times, from early 
in the morning till late at night, and medicines were administered in the usual 
way. I did not hear him cough at aU. 
IJpon his death I sent for Mr. Leigh to open him. I sent to young Mr. 
Leigh, and also to the elder Mr. Leigh. Mr. Nathaniel Leigh came to open 
him, and old Mr. Leigh came afterwards. Young Mr. Leigh came at ten 
o’clock, and I was present when he opened the horse. I examined the chest. 
Upon looking at the lungs after they were taken out, I observed symptoms of 
old disease—the right lohe was indurated or hardened to a considerable extent 
at the part next the sternum or breast-bone. The proper structure of the 
lungs is not hard, but somewhat like sponge. About twelve inches in extent 
the lung was hardened along the breast-bone, which, in a horse, is horizontal. 
The hardened part was about six inches in depth. The left lobe was also dis¬ 
eased, but not so extensively as the right. It was hardened, but not in the 
same part. It was hardened at about the centre of the lung. It was the 
same kind of disease as in the other, and about five or six inches in diameter. 
There were tubercles existing in these hardened parts—substances like curd 
or cheesy matter. From these appearances I could teU that the disease must 
have existed for a considerable time, although I could not tell accurately for 
how long. Tubercles are first formed by subacute or slight inflammation. 
If the inflammation were very acute, it would produce abscesses, or kill the 
animal. The subacute inflammation may arise from different causes—from 
cold, strangles, or from influenza. When cold takes place, if the slight inflam¬ 
mation is not removed in eight or ten days, or a fortnight, coagulated lymph 
is thrown into the substance of the lungs, and that is what we caU induration 
or hardness. When the coagulated lymph has thus been thrown in, blood¬ 
vessels begin to shoot through it, and it becomes organized or hepatized like 
liver. That takes great time, and becomes what is called an organic dis¬ 
ease. It becomes like a part of the body, and the circulation is carried on in it. 
Inflammation of the lungs is generally attended by cough as long as the in¬ 
flammation lasts, but when the part becomes organized—when it is a part of 
the body, the cough ceases, because there is no longer any irritation. Where 
there has been a change of organization like that I have described, the animal 
may be as fat as any other horse, and may continue capable of doing moderate 
work. It would not be more likely to take cold than any other horse ; 
but if cold were taken, the lungs being in that state of disease would be more 
likely to be seriously affected by it, and an increase of the disease would be 
likely to be caused. It cannot be ascertained by the appearance of the lungs 
whether there has been onlv one or more attacks of inflammation. 
Beside the hardness in the lungs, I observed that the intestines were dis¬ 
eased. There was an inflammation of the mucous membrane of the colon and 
of the large intestines. This inflammation of the bowels had been called into ac¬ 
tion by the previous disease of the lungs, and, jointly, they had killed the horse.
