CASE V. A. G., aged 52 at his death. He was a collier from his boyhood,

and wrought during the greater part of his life at Penston colliery in

the parish of Gladsmuir. He was a short-set robust man, and while

labouring at Penston, he enjoyed usually good health, free from cough or

any affection of the chest. When he had attained the age of 48 years,

(1833), he removed from the Penston to the Pencaitland coal-work, and

about six months after making this change, he began to experience a

slight difficulty of breathing, accompanied by a troublesome cough and

feverish nights. The pulse was 84. Various soothing remedies were

administered, which relieved for a little the pectoral symptoms; and as

he felt no decided physical debility, he continued as usual at

underground work. In 1835 I saw him often, and found that his pulmonary

symptoms were becoming more marked; his cough was excessively annoying

in the morning and when going to bed; his expectoration was frothy

mucus, with dyspepsia, palpitation, and occasional headach. The

resonance of the chest on percussion was very slightly impaired, and the

respiratory murmur was variable, being occasionally louder at one time

than another, and often much obscured, from the mucous secretion.

Labouring under this chest affection he still continued his daily

employment till the spring of 1836, when he was entirely laid aside,

being unable to go below ground, or to take the slightest fatigue, for

the smallest exertion produced a fit of coughing; and during a paroxysm

of this kind, he expectorated a few black sputa, which in a few days

disappeared, and gave place to the usual frothy mucous expectoration.

This bronchial discharge was accompanied by considerable relief to the

cough and dyspnoea. By this time, (June 1836), on applying the ear to

the chest, the resonance is dull, and respiratory murmur obscure. The

action of the heart was slow when compared to its former state. The

pulse not beyond 45 in the minute. By the end of this year he appeared

in a half dead state,--but a mere shadow in regard to flesh. He was

expectorating at intervals of some weeks, when the cough became more

severe, a few carbonaceous sputa, and suffering severely from gastric

irritation.[13] During the last week of his life, he expectorated

considerable quantities of black fluid, and died exhausted, January

1837.

_Post-mortem examination_, which was conducted hurriedly, exhibited

extensive effusion into both sides of the chest. The adhesions of the

pleura were strong, and evidently of long standing. There was very

general carbonaceous infiltration throughout the lungs, without

excavations to any extent. Various empty cysts, which could contain a

hazel-nut, were found in the superior and middle lobe of the right, and

throughout the whole of the left lung; in which bronchial twigs

terminated. The pericardium was distended, with limpid effusion. The

right side of the heart was dilated, and filled with dark

treacly-looking blood; and when washed, it appeared pale and bloodless.

Its walls were thin, various patches of brown exudation extending over

both pleuræ. There were several enlarged lymphatic glands, found at the

root of both lungs, filled with black fluid.

In examining the head, the pia mater was found much congested; but there

was no effusion discovered into any of the ventricles of the brain, nor

any other indication of disease.

In tracing the history of this patient, connected with the disease, it

will be observed, that until he came to Pencaitland colliery, he had no

symptom whatever of chest affection. Penston coal-work is exceedingly

well ventilated, and the miners who labour there seldom, if ever, suffer

from the black expectoration, owing to the evolved smoke of every kind

being freely carried off from its underground works, while it is quite

the contrary at Pencaitland, where many colliers, on leaving Penston,

are seized with the disease. This case comes under the second division

of the disease, where the irritative process, the result of the foreign

matter in the lungs, has proceeded so far as to produce a variety of

small cysts, containing fluid, or semi-fluid carbon, following the

course of the bronchial ramifications.

CASE 6. D. L., aged twenty-six years at his death, in August 1837. He

was the son of a collier, at Pencaitland, and engaged at an early age in

putting the coals to his father; and when he was fit for full

collier-work, in 1831, he was employed at the same coal-work. He was a

tall, well-formed, robust young man, and not at all liable to chest

affection. For some time he wrought, as a coal-hewer, but latterly was

induced, (1834), for higher wages, to become a stone-miner in the same

coal-pit, where gunpowder was used extensively in the operations. About

six months after he commenced stone-mining, he became affected with a

short tickling cough, expectoration of pearly tenacious phlegm, hurried

breathing, tightness across the chest, frequent pulse (95), heat of skin

during the night, and occasional throbbing in the head. Being young, and

fearless of any danger from the occupation, although warned of the

consequences, he continued to prosecute it, and twelve months (May 1835)

after he first began, the cough had increased much in severity. The

expectoration was diminished, and had become more difficult to void from

the bronchi, and the breathing was more oppressive, accompanied by a

painful tightness across the chest in the morning. The body was

considerably reduced in bulk to what it previously had been. The pulse

ranged from 80 to 90; the appetite was impaired, and there was in the

morning a tendency to retching. The nocturnal heat of skin continued,

without any moisture, though his body was drenched with a clammy sweat

during the hours of labour. The respiratory murmur was harsh and

extensive at the upper part of both lungs, while the sibilant ronchus

was heard occasionally in the lower lobes. The heart's action was

regular, but impulse strong, on applying the hand to the cardiac region.

The remedies resorted to were blisters, bleeding (at an early stage),

expectorants, and tonics, which, to a certain degree, relieved the more

urgent symptoms.

In October 1835, the disease having made rapid progress, all the

symptoms had become more marked. The cough, from its frequency and

severity, was extremely exhausting, and the expectoration had become

more copious, and of a semi-black colour. The mucous râle was evident in

the upper part of both lungs, while the inferior lobes were dull to the

ear, and on percussion. The heart's action, at this stage, was less

strong, but no peculiarity in its function could be discovered. The

cardiac region exhibited every indication of effusion into the

pericardium. His body was now 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 pleuræ, 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 infiltrated with

carbon into the interlobular cellular tissue. The air-cells were gorged

with tenacious mucus. The middle lobe was partially excavated. The

cellular tissue was considerably disorganized, and similar in diseased

structure to the upper lobe of the left lung, with the exception of a

portion affected by vascular emphysema. The inferior lobe was much

condensed, and loaded with carbon of a very bright black. The mucous

membrane of the bronchial tubes was thickened, and slightly ulcerated.

Various lymphatic glands were found at the root of both lungs,

containing black fluid. The pericardium was considerably distended from

effusion of a straw-coloured fluid. The internal surface of the

pericardium was rough, and both laminæ appeared thickened from

inflammatory action. Effusion into cavity of chest to the extent of

twelve ounces. The heart was natural in appearance, but thin in

substance. The tricuspid and mitral valves were thickened, and

exhibiting minute granulations on their surface. The right auricle and

ventricle were dilated considerably. Aorta, and other vessels proceeding

from heart, were natural. The stomach was small, and exceedingly spongy

in its mucous lining. The intestines were healthy. The kidneys were

small, and peculiarly yellow in the internal structure. The liver was

large, and engorged with dark thick blood; several small carbonaceous

cysts throughout its substance. The spleen was large, soft, and much

congested. The mesenteric glands free from black matter.

_Head._--The arachnoid thickened and opaque; there was very general

congestion of pia mater with dark black blood, and when removed,

convolutions studded over with innumerable dark points. The surface of

the brain was apparently healthy, with an effusion of a light pink-like

fluid into the lateral ventricles. The internal substance of the brain

natural.

This case is interesting, as showing the very rapid course, in some

instances, of the disease to a fatal termination, and also how soon the

strongest man can be brought under its destructive influence. This is

the only case in which carbon was discovered in any of the other organs,

as exhibited in the liver. The above case comes under the third

division, showing extensive excavation of the pulmonary structure.

CASE VII. James R. aged 54 at his death, 1836. He was a large muscular

man, and wrought as a coal-miner in early life at Pencaitland, and, as

far as could be ascertained, he had never been engaged at stone-mining.

At the age of thirty he was obliged to desist work, on account of a

difficulty in his breathing, which he considered to be asthma, and he

was occupied above ground, as the engine-man, during the latter part of

his life. The slightest exertion produced exhaustion and palpitation of

the heart; his bowels were obstinate, and his urinary secretion small in

quantity. His cough was particularly troublesome in the morning, and was

relieved by a free expectoration of frothy mucus. In this condition he

continued, with the cough gradually increasing, for nearly twenty

years, as I understand, when he began to void black sputa, which daily

augmented in quantity till his decease, August 1836.

For some weeks previous to his death, his pulse had become slow and

thready, 36 in the minute. The oedema of the upper and lower

extremities was extensive; the dyspnoea increased considerably; the

countenance was livid; and the body remarkably cold. Stimulants in

considerable quantity were administered without the smallest effect.

Drowsiness supervened; and he was for some days previous to dissolution

in a torpid condition, while at the same time he was quite collected

when roused.

_Post-mortem examination._--On examining the body, the chest was large

and well formed. The effusion into the cellular substance was very

general. The cartilages of ribs were ossified, and both lungs were

adhering strongly to the pleura costalis. There was large effusion into

both cavities of the chest, to the extent of three English pints in

whole. The pleura pulmonalis was much thickened and rough, with false

membrane, and many patches of puckering. Several lymphatic glands in the

anterior part of the mediastinum contained black fluid. The left lung

was carbonaceous throughout its substance. The upper lobe partially

excavated and ragged; the inferior lobe infiltrated and emphysematous.

The right lung was of corresponding black appearance. The lower lobe had

a firm and condensed feel, and when divided, exhibited a mass resembling

indurated blacking. The middle lobe was in part permeable to air; and

there were several small cysts containing liquid carbon, connected with

minute bronchial ramifications. Various indurated knotty bodies were

extended throughout its substance. In the upper lobe, the carbon was

confined principally to the interlobular cellular tissue, and when

pressed in the hand, gave out thick, black, frothy serum. The mucous

membrane of bronchial divisions, when freed from the black matter, was

swollen and eroded as far up as the bifurcation of the trachea. At

several parts these passages were considerably contracted.

The heart was enlarged, and dilated in all its cavities. The valves of

the right and left ventricles wore thickened, from congestion of very

minute veins, and were granular to the feel. The substance of the heart

was soft. There were eight ounces of effusion into the pericardium,

resembling that formed in the cavities of the thorax. The liver and the

spleen were large; the former peculiarly yellow and oily. Several very

large veins, containing inky-looking blood, were seen ramifying its

substance. The spleen was very friable. The kidneys were small, and

apparently healthy.

Brain not examined.

This case comes under the third division of the disease. R.'s case is

peculiarly striking, from the length of time (twenty years or more) that

the carbon was concealed within the pulmonary tissue, and also because

he had never been engaged, as far as known, as a stone-miner; so that

this case, along with others, illustrates the fact, that where the

morbid action is the result of lamp smoke, from the combustion of coarse

oil, and not gunpowder smoke, the disease is much slower in its

progress, but ultimately fatal.

* * * * *

CASE VIII. R. D., aged 37, at his death, 1839. He was the brother of

George Davidson, subject of the first case in this Essay. He began to

labour as a miner, with his brother, in early life, at Pencaitland

coal-work. He first began as a coal-miner, and after being so engaged

for five or six years, he removed to Penston coal-work, which adjoins.

He continued healthy for a considerable length of time, and at his

brother's death, December 1836, he was free to all appearance from any

affection of the chest. He returned, 1836, to Pencaitland coal-work,

where he engaged as a stone-miner, knowing that such employment was

destructive to life; and from that change he dated the commencement of

his disease. Cough, palpitation, dyspnoea, headach, quick pulse (90 in

the minute), made their appearance, soon after he began trap labour, and

these symptoms gradually increased, till he was laid aside in the course

of two years, (1838,) when he first expectorated black sputum.[14] As

his exhaustion advanced, the carbonaceous expectoration became more

copious, and he discharged from the lungs at an average twelve ounces of

fluid, resembling liquid blacking, daily; and he died in a manner

similar to his brother, Case No. 1. Some weeks previous to his death,

his pulse rapidly sank to about 45 or 50, and became exceedingly

feeble;--cold extremities, oedema of the legs and arms, lividity of

lips, eyelids, and ears, preceding dissolution.

_Post-mortem examination._--The chest was contracted; the ribs

unyielding, with extensive adhesions of the pleuræ. Both lungs were of a

dark-blue colour, much puckered from patches of false exudation. There

was extensive effusion into both cavities of the chest; and the right

lung showed carbonaceous infiltration throughout its whole extent. The

superior lobe was excavated, so as to contain a small orange; and about

six ounces of thick, black matter were found in it. The middle lobe was

crepitant, though soaked with black fluid; several impacted lobules were

scattered throughout its substance. The inferior lobe was indurated,

resembling a piece of moist peat. The left lung was cavernous in both

lobes, and the cysts were empty, the contents having been expectorated.

A small portion of the upper lobe was pervious to air. There were

several enlarged bronchial glands at the root of both lungs; and the

tracheal glands contained black fluid. The liver was large, and its

substance soft.

_Head._--There was extensive congestion of the blood-vessels of the

brain, with effusion into the lateral ventricles. The viscera of the

abdomen were extensively congested, with slight effusion into the

peritoneal cavity.

It will be observed in referring to the history of this case, that till

the time this man became a stone-miner, and carried on his operations

with the aid of gunpowder, he had no symptom of the disease of which he

died, and it is evident that the disease, if commenced at all, had made

little or no progress till after his return from Penston colliery to

Pencaitland, and after he had inhaled the residuum of gunpowder

combustion, therefore the disorganization of the pulmonary structure was

to all appearance effected between the summer of 1836 and December 1838,

showing decidedly the very irritating character of gunpowder smoke upon

the delicate tissue of the air-passages.

CASE 9. J. D., aged 37, at his death, April 1844. He was a well formed

man, with a fully developed chest. At so early an age as seven years, he

engaged in the labour of the coal-pit at Preston-Hall, Mid-Lothian, and

he continued to prosecute that employment for a period of 15 years, when

he was obliged to relinquish the work on account of an affection of the

chest, being, as he termed it, "touched in the breath." During the

subsequent 15 years of his life, he had never once entered a coal-pit,

nor had he any connexion with coal-works, but earned his bread by the

trade of a travelling merchant. He had suffered much in his wanderings,

from his breathing,[15] for more than two years continuously, while loss

of appetite, and thoracic irritation, had rendered his physical frame as

weak as that of a child.

When I first saw this man, which was about a month before his death, he

laboured under rending cough, with a scanty tough mucous

expectoration--oppressive dyspnoea, ascites, general anasarca,

occasional giddiness, and throbbing headach on motion, or on assuming

the standing position. His countenance was of a light blue or slate

colour, and his upper and lower extremities had much the same

appearance. His lips, eyelids, ears, and nose, were swollen and livid,

and his eye-balls effused, and apparently projecting from the sockets.

His sight was impaired and hazy. There was continued feeling of cold,

with occasional rigors, and difficulty in keeping the extremities warm.

There was considerable exhaustion upon the slightest exertion. The half

reclining posture was the only one in which he was comfortable. The

pulse was exceedingly slow, not above 36 in the minute, it was small,

and often imperceptible at the wrist. There was considerable weight and

feeling of oppressive fulness in the region of the heart, which was dull

on percussion. On applying the ear to the chest, little or no râle

whatever was discernible, and the action of the heart was almost

inaudible. He had a sensation as of great weight in the head, and

difficulty in raising it. Ho suffered from restless nights, short

hurried breathing, with a feeling and dread of suffocation, evident

fulness and enlargement in the region of liver, and inability to turn to

the right side. The urine was small in quantity, of a bluish colour, and

coagulable, irritability of stomach, and the bowels were obstinate and

difficult to move, even with drastic purgatives. The treatment was

merely palliative, no stimulant seemed to have any effect in exciting

the system. Ascites and general anasarca were considerable, giving the

body a large appearance. For some days previous to his dissolution,

there was increased lividity of countenance, and little or no action of

heart. He had at no time expectorated carbon, even during many severe

paroxysms of cough. Upon inquiry, I found that this man had been a

companion in labour to R. R. (whose case No. 2, is fully reported,) at

Preston-Hall colliery, and from the morbid appearances found in R.'s

chest, and from the character of the coal-work in which both were

engaged, I was induced to believe Duncan's to be a similar case. In

ascertaining his early history, I found him to be a robust powerful man,

though troubled with a cough and hurried breathing from his first

becoming a collier, circumstances very usual with those who engage in

difficult mining operations, and which they erroneously attribute to

want of air, nothing more.
