considerably emaciated, and the anterior
part of his chest was so much contracted, as to oblige him to stoop to a
great degree. Under this load of disease, he continued his employment of
a stone-miner, gradually losing flesh, with a rapidly increasing black
expectoration; and having several dependant on his exertions, he
resolved to work, while he could keep on foot, which he did till
September of the following year, (1836) when his once powerful body was
so reduced, from disease, and his cough so incessant, that he was unable
to move or speak without great fatigue. He preferred the sitting
position, as giving him most freedom in breathing. The pulse was rather
slow and small; the heart's action languid, and there was an evident
increase of dulness upon percussion over cardiac region. At this, the
closing period of the disease, (November 1836) he first complained of
drowsiness, accompanied by headach. The countenance was pallid; the eyes
sunk and inanimate, and the body tending to be cold; the urinary
secretion of a dark brown colour, and precipitates a dark deposit. The
bowels were exceedingly obstinate, with little change in any of the
symptoms; he lingered till January 1837.

_Post-mortem examination._--The body was much emaciated. The thorax was
large, and well arched. On removing the anterior part of the chest, the
lungs appeared to be fully developed, and of a dark blue colour. There
were several very slight adhesions between the pleurae, and the effusion
into both cavities was small in quantity. The pleura costalis was almost
free from any exudation, but there were a variety of small patches of
false membrane throughout the pleura pulmonalis. The left lung exhibited
general carbonaceous infiltration. The upper lobe was partially
excavated. The pulmonary structure, internally, was ragged and easily
torn, and these cavities communicated with the bronchial divisions, the
walls of which formed various septa. The inferior lobe was almost
impervious to air. The minute bronchial ramifications and corresponding
lobules were impacted with dense carbon. There were several clusters of
small cysts throughout this lobe, containing carbon in a fluid state. A
portion of this lobe sank in water from its density, and when squeezed
with the hand, thick fluid carbon, containing hardened particles, could
be expressed from it. The right lung was similar in external appearance
to the left. The upper lobe was crepitant, though infiltrat
