HEALTH AND LONGEVITY.

[The Effects of Arts, Trades, and Professions, and of Civil States and

Habits of Living, on Health and Longevity; By C. Turner Thackrah, Esq.

Second Edition. Longman, 1832.]

The author of this book is a medical practitioner at Leeds; and the

object of his work, than which there can be none more important, is to

exhibit, in most cases from personal observation, the influence of

particular occupations on the health of the individuals pursuing them

and on the duration of their lives. His general impression is, that the

employments of large manufacturing towns, such as Leeds, Manchester,

Birmingham, and Sheffield, are decidedly unfavourable to health and

consequently to happiness; and, he says, with regard to the town in

which he lives, “every day we see sacrificed to the artificial state of

society one, and sometimes two victims, whom the destinies of nature

would have spared.” Doubtless, continued and laborious occupation in

crowded rooms is not favourable to health; but, on the other hand, it

should be considered that these very employments, by increasing the

comforts of the great mass of consumers, have a direct tendency to

secure the general health of the community; and that if the term

“destinies of nature” is to be taken to apply to man in an uncivilized

state, it is perfectly certain that the artisan who pursues his calling

under the most unfavourable circumstances is far better off in his

physical condition, and therefore in his capacity for long life, than

the poor dweller in the forests of America or the wilds of Africa, whose

supply of food and clothing is wholly dependent upon chance, and who is

entirely without medical aid in sickness. It is a well-known fact, that

in this country, a century ago, the average mortality in a year was one

in thirty; it is now about one in sixty; that is, where one person in a

year dies now, two died a century ago, as compared with the gross amount

of the population. When it is considered therefore, how large a number

of our countrymen are employed in manufactures, it would seem that, upon

the whole, manufacturing employments are not so unfavourable to health

as might at first be imagined. An attentive examination of Mr.

Thackrah’s book will show, that even in the most apparently unwholesome

employments there is a wonderful compensation in the power of habit; and

it is beyond all doubt that cleanliness, temperance, and that habitual

cheerfulness which leads the spirit to triumph over the most adverse

circumstances, will enable those who would appear necessarily the most

unfortunate, to pass through life with comparative happiness and

comfort. Still, it is very important to examine what occupations have

the most unfavourable influence on health,--not with the view of making

those who follow them dissatisfied with their condition, but for the

purpose of suggesting every preventive and remedial measure, within the

range of human knowledge, to the attention of the capitalist, whose

first duty is to provide for the happiness of those around him; and

above all to show the working-man himself how much he has it in his own

power to mitigate the evils which he cannot altogether avoid. In this

point of view Mr. Thackrah’s book deserves the most serious

consideration of all classes. It is most satisfactory to know, upon Mr.

Thackrah’s authority, that “in many of our occupations the injurious

agents might be immediately removed or diminished.”

For the convenience of his inquiry the writer before us divides society

into five great classes, viz.--I. Operatives. II. Dealers. III. Master

Manufacturers, and Merchants. IV. Men independent of business and

labour. V. Professional Men.--The first section of operatives he

sub-divides into--1, those whose employments are chiefly in the open

air; 2, those whose employments are carried on in an atmosphere confined

and impure; 3, those whose employments produce dust, odour, or gaseous

exhalations; 4, those whose employments injure or annoy by acting on the

skin; 5, those whose employments expose them to wet and steam; 6, those

who are exposed to a high temperature, or great variations of

temperature. When we state that in these six sub-divisions of the great

class of operatives, Mr. Thackrah describes the peculiar effects of

about two hundred different employments, it must be evident that we

cannot attempt even to enumerate the occupations whose influence upon

health is here noticed. To show, however, the interesting mode in which

this inquiry is for the most part conducted, we subjoin an abridged

extract, descriptive of the condition of the grinders and machine-makers

of Sheffield:--

“Dr. Knight, in the North-of-England Medical Journal, states that the

fork-grinders, who use a _dry_ grindstone, die at the ages of 28 or 32,

while the table-knife grinders, who work on _wet_ stones, survive to

between 40 and 50. Dr. K.’s paper very properly alludes to the

combination of injurious agents and circumstances. It is not, merely the

pernicious employment, but the want of sieve and ventilation in the

apartments where the men now work,--the want, moreover, of that exercise

in the open air which they formerly took in going to work and returning

from it; and finally, the intemperance which results from their

congregation, and still more from their desperation of life. It appears,

that in 1822, ‘out of 2,500 grinders, there were not 35 who had arrived

at the age of 50, and perhaps not double that number who had reached the

age of 45; and out of more than 80 fork-grinders, exclusive of boys, it

was reported that there was not a single individual 36 years old.’ The

symptoms of the grinders’ disease are those of slow but certainly fatal

consumption. The remedies judiciously recommended by Dr. Knight, are,

1st. Dusting the machinery, before the work commences: 2nd. Great

reduction in the time of labour: 3rd. Use of wet stones as much as

possible; 4th. Large flues to be laid on the floor for ventilation, and

currents of air to be forced through them by the machines: 5th.

Fork-grinding to be confined to criminals.

“_Draw-filing cast iron_ is a very injurious occupation. The dust is

much more abundant, and the metallic particles much more minute, than in

the filing of _wrought_ iron. The particles rise so copiously as to

blacken the mouth and nose. The men first feel the annoyance in the

nostrils. The lining membrane discharges copiously for some time, and

then becomes preternaturally dry. Besides the dust there are some very

bright scales, called _kisk_, very visible though scarcely tangible,

which rise from the castings, as these are taken out of the moulders’

boxes, and considerably irritate the air-tube. But these scales produce

much less frequent annoyance than the particles detached by the file,

notwithstanding the dust of the employ. Respiration is not promptly

impeded. Of ten men whom I examined with reference to this point, but

one had difficulty of breathing as a _primary_ symptom. The subsequent

symptoms are determined chiefly by intemperance, and the constitutional

disposition to consumption. The machine-makers earn high wages, and many

consequently are addicted to liquor. In all, the breathing becomes, in a

few years, more affected by exertion; but in the intemperate it is most

affected; the morning cough is attended with retchings, disorder of the

liver and of the other organs of digestion becomes established, and at

length pulmonary consumption closes the list of symptoms. Scarcely a

filer can be found in health. Few bear the employ, even modified as it

is by frequent changes of material, for twenty-five years. Only one

instance have I been able to find of a working filer exceeding the age

of fifty. What can be done to prevent this lamentable waste of life?

Magnetic mouth-pieces, which attract the particles of iron inhaled in

respiration, and thus greatly diminish the quantity which would enter

the air-tube, were many years ago introduced in Sheffield, and ought ere

this to have been more extensively tried. But there is a strange apathy

both among the men and the masters.”

If the working-classes, in the ordinary acceptation of the term, have

abundant evils in their employments, those who would appear to be placed

under happier circumstances are not exempt from those corroding cares

and unnatural excitements which injure health, and destroy life, as

speedily as crowded rooms and extreme heat or cold. Let us take Mr.

Thackrah’s description of the class of shopkeepers:--

“They are generally temperate in their diet. They injure health, not by

direct attacks, not by the introduction of injurious agents, but by

withholding the pabulum of life--a due supply of that pure fluid, which

nature designed as food for the constitution. Be it remembered that man

subsists upon the air, more than upon his meat and drink. Numerous

instances might be adduced of persons existing for months and years on a

very scanty supply of aliment, but it is notorious that no one can exist

for an hour without a copious supply of air. The atmosphere which

shopkeepers breathe is contaminated and adulterated; air, with its vital

principles so diminished, that it cannot fully decarbonize the blood,

nor fully excite the nervous system. Hence shopkeepers are pale,

dyspeptic, and subject to affections of the head. They often drag on a

sickly existence, die before the proper end of human life, and leave a

progeny like themselves.”

The merchant and manufacturer is probably not more fortunate, though he

may appear to have a greater command of worldly comforts:--

“Of the causes of disease, anxiety of mind is one of the most frequent

and important. When we walk the streets of large commercial towns, we

can scarcely fail to remark the hurried gait, and care-worn features of

the well-dressed passengers. Some young men, indeed, we may see, with

countenances possessing natural cheerfulness and colour; but these

appearances rarely survive the age of manhood. Cuvier closes an eloquent

description of animal existence and change, with the conclusion that

‘life is a state of force.’ What he would urge in a physical view, we

may more strongly urge in a moral. Civilization has changed our

character of mind as well as of body. We live in a state of unnatural

excitement:--unnatural, because it is partial, irregular, and excessive.

Our muscles waste for _want_ of action; our nervous system is worn out

by _excess_ of action. Vital energy is drawn from the operations for

which nature designed it, and devoted to operations which nature never

contemplated. If we cannot adopt the doctrine of a foreign philosopher,

‘that a thinking man is a depraved animal,’ we may without hesitation

affirm, ‘that inordinate application of mind, the cares, anxieties, and

disappointments of commercial life, greatly impair the physical

powers.’”

Let us see if the _idle_ man of independent fortune is placed under more

favourable circumstances for the enjoyment of existence:--

“A man supplied with food and comforts, without labour and care, has

constantly full opportunity of attending to health. But man is a social

animal. The Creator has ordained that no individual shall live to

himself, and live in happiness. A man without an object is like a tree

without a leading shoot. He has not the vigour of his fellows; his

strength is either dissipated in irregular pursuits, or decays from

listlessness. In professions and trades the nervous system is often

exhausted by excessive application; here, as frequently it declines from

the want of exertion. Need I add, that the vices which result from the

want of employment, undermine the constitution and shorten life.”

Mr. Thackrah has stated, in many instances, the modes which he conceives

applicable to the mitigation or removal of the evils of particular

employments. It is, of course, not within our province to follow him in

these details. But throughout his work he notices also those habits

which are best calculated to preserve man in health in every situation.

These best remedies, which are in a great degree within the reach of us

all, may be comprised in the words _temperance_, _cleanliness_,

_exercise in the open air_, and _cheerful relaxation_. It should be the

aim of every working-man to employ these remedies for any evils of his

occupation, as far as he can himself; it is the duty of every employer,

as much as in him lies, so to regulate his periods of labour, that no

artisan shall be unable, from want of time, to take his evening walk in

the fresh fields, to cultivate his little garden, or to afford an hour

to that improvement of his mind which will invigorate and refresh his

body, by the cheapest and the purest of all pleasures.
