of the lungs. A portion of the lungs, more particularly the right lobe, was 
converted into a solid form, the effect of chronic disease. The left lobe was 
similarly but not so extensively diseased. I examined the hard substance 
in the right lobe, which had more the appearance of liver thaa the natural 
appearance of the lungs. It had no passages for air through it. I discovered 
tubercles in both lobes. I took out a portion of the lungs, and preserved 
it in spirits. In my judgment the cause which produced that state of the 
lungs must have existed some months. 
The original or exciting cause might have been over-exertion or cold, and 
that would produce acute inflammation, if neglected. The acute inflamma¬ 
tion might have been treated, and the person who treated it might have 
considered that it was cured; but some portion of it might still have remain¬ 
ed in a chronic form. Chronic disease is the consequence of acute inflam¬ 
mation. During the period of acute inflammation of the lungs, there would 
generally be a cough. In chronic inflammation the cough might continue, 
but not to the same extent. Acute inflammation may or may not entirely 
disappear: supposing acute inflammation to have entirely disappeared, there 
would probably be an occasional cough. The lungs, when they are in a state 
of chronic disease, are more liable to acute inflammation on an inflamma¬ 
tory attack of any other organ. 
I tried the lungs in spirits; the diseased part sunk. This is a part I took 
from the horse [the witness produced a bottle containing a portion of the 
lungs preserved in spirit] : the part that is sunk is the diseased part; the 
other is not quite perfect; there is some disease existing in it. 
Cross-examined hy Mr. Sergeant Bompas .—I let the lungs sink in spirits, it 
also sunk in water. I saw the horse shortly after he died, and at a time when 
a veterinary surgeon could ascertain the cause of death. The inflammation 
of the bowels was slight; I should say that the inflammation of the lungs 
was existing when the inflammation of the bowels came on. In my judg¬ 
ment, the disease of the lungs might have produced inflammation of the 
bowels. When inflammation is very -vdolent in one organ, it may extend by 
sympathy to another. The inflammation of the lungs did not appear to be 
very violent, but it was sufficient to cause death. Some parts of the lungs 
were not diseased; those that were so, were hard or solid, and appeared to have 
been so for a considerable length of time. In some parts where the disease was 
violent, the lungs appeared to be disorganized; this is generally the case 
w'here there is violent inflammation. This occurred in patches at various 
parts—some an inch or two distant from others; it was more particularly so in 
the centre, but it was more or less throughout the whole of the lung. There was 
no gangrene or mortification. The lungs were not come to a state of rotten¬ 
ness. There might be acute inflammation without this. There was also 
chronic inflammation, or the remains of it. Chronic and acute inflammation 
may exist in the same place at the same time. The centre was more dis¬ 
organized than the edges; but there was some inflammation there. The 
left lobe w’as diseased and disorganized, but not so extensively as the right. 
Where the ^ chronic disease existed, the acute appeared to have been most 
violent. The disorganization w'as of the same kind as usually exists where 
there is acute inflammation, only more violent. Horses do not usually die 
of acute inflammation of the lungs, unless chronic inflammation has existed 
previously; then the acute disease generally puts an end to life in a short 
time. Simple acute inflammation may continue for a longer time. When 
acute inflammation becomes violent, there is usually disorganization exist¬ 
ing in a corresponding violent degree. 
The lungs of the horse occupy the greater part of the chest. When 
the horse is standing, they are suspended from the centre, and rather in the 
posterior part. The edges or thinnest parts are dependent, and nearest the
