terlobular cellular tissue, leaving the bronchial
ramifications respirable, and lubricated with frothy mucus. The middle
lobe presented a solid appearance, and contained a mass of indurated
black matter, of the size of a largish apple, and consistency of
consolidated blacking. The surrounding parenchymatous substance was
disorganized, and undergoing the process of softening. In dividing the
indurated substance, its internal structure exhibited a variety of
greyish lines, forming parallel and transverse ramifications, which
resembled small check in appearance, and which, when more accurately
examined, was ascertained to be the disorganised walls of the minute
air-cells and cellular tissue. The inferior lobe presented a state of
complete infiltration, with the air-cells generally entire, and on
putting a piece of it into water, it showed its density by sinking.

When we examine the morbid appearances in this case, and compare them
with the symptoms--when we consider that nearly all the respiration
carried on in this man's chest, was performed in the upper lobe of the
right lung, we are not surprised at his sufferings, nor is there much
difficulty in explaining the very painful dyspnoea, on his attempting
the recumbent position; and as death was instantaneous, it was evident
that the immediate cause was the bursting of the left pulmonary cyst
into the corresponding bronchus; the fluid carbon thus finding its way
to the trachea, produced suffocation.

The liver was exceedingly large, projecting outwards and downwards from
under the ribs, and pushing up the diaphragm. Its substance was soft,
engorged with dark blood, and easily torn. There was no carbonaceous
deposit throughout its structure, and its weight was upwards of twelve
pounds. There was a considerable quantity of very dark bile in the
gall-bladder. The heart was large, soft, and pale. There was
considerable attenuation of the walls of both auricles and ventricles.
The coronary veins were much distended with dark blood. The columnae
carneae of the right ventricle were exceedingly slender and bloodless;
the tricuspid valve was much thickened, and studded on both sides with
small cartilaginous granules; the other cavities of this organ were
apparently healthy, though thin in substance. The pericardium, which was
rough, and much distended, exhibited a variety of false membrane on its
internal surface, of a dark brown colour, and contained about eight
ounces of dark fl
