The cartilages of the ribs were ossified. The left cavity of the
pleura contained about twelve ounces of water; the right, about three
ounces. The lungs, externally, were dark coloured, especially the
posterior lobes; internally, they were very firm, and, in some places,
as dense as the substance of the liver. A frothy mucus was effused
from them in great quantities. They were coloured by very dark blood,
especially in the middle portion of the left superior lobe. One or two
calcareous concretions were observed in them. The pericardium was a
little firmer than usual, and contained about five ounces of water.
The heart was enlarged, and covered with tough fat. In the right
auricle, and ventricle, was some coagulated blood. The tricuspid
valves had lost their smoothness and transparency; the semilunar
valves of the pulmonary artery were cartilaginous at their bases. The
left auricle and ventricle, particularly the first, contained
coagulum. The mitral valves were roughened by many bony spots.
Considerable ossification had taken place in the semilunar valves of
the aorta, so that one of them had quite lost its form; and the aorta
was ossified for the space of a square inch, at a small distance from
the valves. The coronary arteries were also ossified.
