uid, similar to that found in the cavity of the pleura.
In tracing the bronchi from the lungs to the bifurcation, the mucous
membrane, which was smeared with fluid carbon, appeared much irritated,
and considerably thickened, diminishing the diameter of these passages;
and there were found externally at the root of the lungs, and around the
bronchi, several large glands, containing a fluid to all appearance
carbonaceous. The trachea showed a similar irritated condition with that
of the bronchi. A little above the bifurcation, and at the back part of
the trachea, a cluster of lymphatic glands were found, some of them the
size of a horse bean, filled with carbon.

_The spleen_ was very large, and much darker than usual, highly
congested with venous blood, easily torn with the fingers, and weighed
about three pounds. Kidneys small, pale, and soft; bladder small, and
corrugated; large accumulation of light brown fluid into the cavity of
the abdomen, to the extent of two Scotch pints. The viscera were much
compressed from effusion. There was a rough brown exudation upon the
surface of the peritoneum and intestines. The stomach was contracted to
a small size. The mucous membrane was soft, pultaceous, and easily
removed, tinged with dark green bile. The lymphatic glands along both
curvatures were small and flaccid, and contained no black matter. The
intestines appeared empty and contracted. The duodenum showed the same
softened state of its mucous membrane as was exhibited by the stomach.
The mesenteric glands were free from any disease. The head, on removing
skull-cap, dura mater found natural; serous effusion to small extent
under the arachnoid; very general congestion of the pia mater, giving
both hemispheres of the brain a blackish appearance. The superior
longitudinal sinus was filled with dark, inky-looking blood. In removing
the pia mater, the convolutions of the brain were firm, and appeared
natural. There was a light brown effusion into both lateral ventricles
to the extent of about an ounce. Reid, when he first came to
Preston-Hall, had inhaled the evolved smoke of the coal-mine, thereby
laying a foundation of this infiltrated mass. It must be manifest to
every one who follows out the history of this case, and attends to the
morbid appearances found within the chest, that there was a progressive
accumulation of carbonaceous matter going on in the substance of the
lungs from the time the patient engaged in working this
