HYGIENIC CHANGE OF AIR.

The age of hygiene is rapidly approaching, when the exhibition of

drugs will be the exception instead of the rule in medical treatment.

For this reason, the effect of climate on disease is rising into a

subject of first-rate importance, and, no longer a prejudice or a

tradition, submits to the investigations of science. The chief recent

writers on what we already presume to call climatology, are Sir James

Clark in England, Schouw in Sweden, and Carrière in France; and now

there comes Dr Burgess, armed with the united authority of these

physicians, and with his own experience, to indoctrinate the public as

well as the profession. His book is of moderate size and price, and we

recommend it to all invalids, whether they are able to travel abroad,

or are confined by circumstances to their own country; but in the

meantime, as the subject is both new and interesting to general

readers, we propose giving them an inkling of what it contains.[2]

We do not mean that the subject of climate is new in itself:

it is only new in its treatment. We have all, from our earliest

youth, heard of the effects of climate; we have all been brought

up to believe in certain foreign places; and we have all observed that

when--consumption, for instance--approaches its last stage (rarely

before), it is shipped off, as a matter of course, for Italy or the

south of France. And, alas! we have all heard from the wan lips of the

stricken one excluded by poverty from the privilege of foreign travel:

'If I could but get to a warm climate, I should live!' Such notions,

right or wrong, depended exclusively upon habit or prejudice. Experience

had no effect upon them, any more than it had upon the orthodox course

of medicines which entitled the death of a patient to be considered

professionally legitimate. Sometimes, indeed, the venue was changed, and

one place became more fashionable than another to die in. Here the group

of English tombs grew gray and ancient, and there a new city of the

silent sprang up with the suddenness of an American emporium. But still

the cry was: 'A warm climate! Give us Italy, or we perish!'

But we need not say the cry _was_: it continues to this moment. Such

impressions are long of being dispelled; it takes a great many years

for the voice of doubt even to reach completely the public ear; and we

think it a privilege to be able to take such advantage of our wide

circulation as will give repining invalids to understand, that the

advantages of a foreign climate are closely limited by one portion of

the profession, and considered by another portion as highly

problematical, if not entirely visionary. This applies, however,

mainly to consumption; for the advantages of the climatic change are

seldom denied in dyspepsy, rheumatism, scrofula, and the tribe of

nervous diseases. Even in these, however, the locality chosen is

rarely a proper one. There are countries which, if they could only

obtain the stamp of fashion, would be invaluable to the invalid. 'The

climate of Norway, for example,' says Dr Burgess, 'is admirably

suited, during several months of the year, between the middle of May

and the middle of September, for certain forms of dyspepsy, lesions of

the nervous system affecting the mind, or that form of general

innervation which results from an overwrought brain, and diseases of

repletion. But Norway is little frequented, because it is not

fashionable, although it would be difficult to point out a more

appropriate occasional residence for the numerous class of invalids

just mentioned, than Christiania, with its picturesque environs,

sublime scenery, and clear and rarefied atmosphere.'

The non-professional predilection in favour of a warm climate for

consumption, may be referred, we suspect, to the analogy that exists

between the earlier stages of that disease and those of a common cold.

In fact, in most cases in this country, consumption is for a long time

styled a cold; then it becomes a bad cold; then a worse; till it is

impossible to withhold from it the more formidable name. A cold,

however, it should be considered, occurs as frequently in summer as in

winter; and in neither is it owing to the temperature, whether high or

low, but to the _atmospheric changes_. The warmer the weather is, the

greater will be the morbific effect of a cold draught of air. That a

warm climate _in itself_ is neither prevention nor cure in

consumption, may be inferred from the prevalence of the complaint in

all latitudes. In India and in Africa it is as rife as in any part of

Europe. By the Army Reports from Malta, we find that upwards of 30 per

cent. of the whole number of deaths throughout the year is caused by

phthisis. In Madeira, according to Dr Heineken, Dr Gourlay, and Dr

Mason, no disease is more common among the natives than pulmonary

consumption. At Nice, it is stated by Dr Meryon, more natives die

annually of consumption than in any town in England of the same amount

of population. In Genoa, one of the most prevalent and fatal of the

indigenous diseases is pulmonary consumption. In Florence, pneumonia

is marked by a suffocating character, and rapid progress towards its

last stage. In Naples, 1 death from consumption occurs in a mortality

of 2-1/3; while in the hospitals of Paris, where phthisis is

notoriously prevalent, the proportion is only 1 in 3-1/4. In short, in

all the celebrated sanatoria to which we fly for relief, we find the

disease as firmly established as at home.

If we examine the analogies presented by the history of the inferior

animals, we find no argument in favour of a foreign climate. The

fishes, birds, and wild beasts of one region, die in another. 'Man,

although endowed in a remarkable degree, and more so than any other

animal, with the faculty of enduring such unnatural transitions,

nevertheless becomes sensible of their injurious results. For familiar

illustrations of this influence, we have only to look to the

broken-down constitutions of our Indian officers, or to the emaciated

frame of the shivering Hindoo who sweeps the crossings of the streets

of London. The child of the European, although born in India, must be

sent home in early life to the climate of his ancestors, or to one

closely resembling it, in order to escape incurable disease, if not

premature death. Again, the offspring of Asiatics born in this country

pine and dwindle into one or other of the twin cachexiæ--scrofula and

consumption; and, if the individual survives, lives in a state of

passive existence, stunted in growth, and incapable of enduring

fatigue. If such extreme changes of climate prove obnoxious to the

health of individuals having naturally a sound constitution, how are

we to expect persons in a state of organic disease to be thereby

benefited? In fact, view the subject in whatever light we may, we must

eventually arrive at the natural and rational conclusion--that nature

has adapted the constitution of man to the climate of his ancestors.

The accident of birth does not constitute the title to any given

climate. The natural climate of man is that in which not only he

himself was born, but likewise his blood-relations for several

generations. This is his natural climate, as well in health as when

his constitution is broken down by positive disease, or unhinged by

long-continued neglect of the common rules of hygiene.' It is Dr

Burgess's theory, therefore, that when change is necessary, a

modification of the patient's own climate--that is to say, change of

air in the same climate--is more in accordance with the laws of

nature, and more likely to effect good, than a violent transition to

warmer countries.

With regard to the curability of this disease, there is now, we

believe, no doubt of the fact, although, unfortunately the process has

not yet come completely into the hands of the physician. That a cure

has frequently taken place, somehow or other, even in advanced stages

of pulmonary consumption, has been demonstrated by _post-mortem_

examinations; but nature herself seems, in these cases, to have been

her own doctor, for no mode of treatment of general applicability has

been discovered. Some think that the progress of tubercles may be

arrested in the first stage--others, that nothing can be effected till

the second. Some resort to the water-cure--others, to the still more

marvellous Spanish baths of Panticosa; and others, again, swear by

cod-liver oil. As to the last remedy, our author quotes the statements

of Dr Williams, 'that the pure fresh oil from the liver of the cod is

more beneficial in the treatment of pulmonary consumption than any

agent, medicinal, dietetic, or regimenal, that has yet been employed.

Out of 234 cases carefully recorded, the oil disagreed, and was

discontinued, in only 9 instances. In 19, although taken, it appeared

to do no good; whilst in the larger proportion of 206 out of 234, its

use was followed by marked and unequivocal improvement--this

improvement varying in degree in different cases, from a temporary

retardation of the progress of the disease, and a mitigation of

distressing symptoms, up to a more or less complete restoration to

apparent health. The most numerous examples of decided and lasting

improvement, amounting to nearly 100, have occurred in patients in the

second stage of the disease, in which the tuberculous deposits begin

to undergo the process of softening. The most striking instance of the

beneficial operation of cod-liver oil in phthisis, is to be found in

cases in the _third_ stage--even those far advanced, where consumption

has not only excavated the lungs, but is rapidly wasting the whole

body with copious purulent expectoration, hectic, night-sweats,

colliquative diarrhoea, and other elements of that destructive process

by which, in a few weeks, the finest and fairest of the human family

may be sunk to the grave. The power of staying the demon of

destruction sometimes displayed by the cod-liver oil is marvellous.'

Dr Burgess, however, although witnessing the same results even in

far-gone cases, limits their duration to a year or eighteen months,

after which the medicine lost its effect. Although the oil, therefore,

is serviceable through the process of nutrition, he considers it no

specific, and concludes on the subject thus: 'All that our present

knowledge enables us to state positively on the subject is this:

cod-liver oil is the most effectual stay to the progress of

consumption, in a great majority of cases, that we possess; this

salutary action is not always lasting, and there are cases in which

its administration cannot be borne, and others in which it produces no

good effects whatever. In those cases in which the stomach rejects the

pure oil, if it be given in combination with phosphoric acid, it will

generally be borne easily, and the acid will assist the tonic action

of the oil.'

The non-professional notion respecting the curative powers of climate

is, that by breathing a mild and soothing atmosphere, the phthisical

patient withdraws irritation, and leaves nature at liberty to effect

her own cure. But this, it seems, is entirely erroneous, inasmuch as

it is through the skin, not the lungs, that a warm climate acts

beneficially. When an atmospheric change takes place so as to produce

a chill, 'whereby the cutaneous transpiration is instantly checked,

the skin then becomes dry and hard, so that the respiratory organs

suffer from the excessive action they now undergo, for the matter of

transpiration must be eliminated through the lungs if the action of

the skin be interrupted.' This is illustrated by the instantaneous

relief usually afforded by free perspiration in cases where difficult

breathing and oppression of the chest have been occasioned by

artificial heat. What really soothes, therefore, is _equability_ of

climate, not high temperature. Some authors even think that a cold

climate is more suitable for consumption than a warm one, and point to

Upper Canada, with its pure, dry, tonic atmosphere, affording hardly

any trace of the complaint at all.

Here we might stop, as the nature of our work precludes our following

Dr Burgess in his exposition of the action of climate on the lungs and

skin; but it may be useful, and at any rate amusing, to trace his

iconoclastic progress through the popular shrines of Hygiea on the

continent.

Malta is a famous resort for phthisical patients, although during the

winter and spring the weather is cold and variable, and in autumn the

sirocco is frequent. When a sirocco has blown for some days, it lulls

suddenly, and is succeeded by an equally strong breeze from the

north-west, contrasting violently with the former in temperature and

everything else. The extremes of heat and cold are as great here and

in other places in the Mediterranean as in London. In Malta, our

author saw five or six cases of bronchitis, which in a single month

terminated in incurable phthisis; and in two cases, six weeks only

elapsed between the first signs of the tuberculous deposit and the

death of the patients.

Madeira, a still more popular sanatorium for this disease, is a

complete delusion. Instead of the climate being essentially dry, it is

saturated with humidity during a great part of the year; and the

peculiar sirocco of the place is of a hot, dry, irritating nature. An

intelligent medical author, who had resorted to Madeira for change of

air, remarks, that 'very frequent and remarkable variations in a given

series of years, incontestably prove that Madeira is no more to be

relied on than any other place for certainty of fine weather, and that

it has equally its annual variations of temperature.... From what has

been stated by writers, a person might be led to believe that disease

was scarcely known there; but I am afraid, that were the subject

thoroughly investigated, as it ought to be, few places would be found

where the system is more liable to general disorder; while, at the

same time, I suspect that the average duration of life would turn out

to be inferior to that of our own country.'

Our author knows no place more unfavourable to patients suffering from

organic diseases of the lungs, than the far-famed sanatoria--Aix and

Montpellier. The atmosphere is pure, but ever and anon keen and

piercing, and the _bise_ and _marin_--one cold and cutting, and the

other damp--irritate the lungs, and excite coughing. Add to this, that

Provence is proverbially the land of dust, and, what is worse, the

land of the _mistral_--a wind from the north-west, which carries

stones, men, and carriages before it. 'For several days in spring the

climate may no doubt be delicious, although, however, always too warm

about mid-day, when suddenly the mistral, of evil celebrity, begins to

blow. It is difficult to give an adequate idea of the change, or of

the injurious effects of the climate under the influence of this

scourge. The same sun shines in the same bright blue sky, but the

temperature is glacial. The sun is there only to glare and dazzle, and

seems to have no more power in producing warmth, than a rushlight

against the boisterous winds, which chill the very marrow in one's

bones. During the prevalence of this wind, it is impossible to stir

out of doors without getting the mouth and nostrils filled with dust.

All nature seems shrivelled and dried up under its baneful influence.'

Nice, likewise, is scourged by the mistral, which there, however,

divides its empire with winds from the north and north-east. 'But one

of the greatest vices characterising the climate of Nice, if not the

greatest, is the remarkable variation of temperature noticed between

day and night--in the sun and in the shade. The land or continental

winds prevail during the night; the southerly or maritime during the

day. The former are cold and dry; the latter, soft and humid. As soon,

therefore, as the former subside, and the sun rises in the horizon,

the humidity commences to shew itself in the atmosphere; whilst, on

the contrary, when the diurnal winds cease, and the sun sets, the

above hygrometric condition of the air disappears.' M. Carrière cannot

conceive why our countrymen prefer Nice to a milder climate, and

considers that the annual mortality in the English colony ought to

discourage other hectic invalids from going thither.

Central Lombardy is, in general, characterised by marshy swamps

poisoning the whole atmosphere with their miasmatic exhalations. The

meteoric influences are decidedly cold and variable; and the 'extremes

of temperature increase in proportion as we approach the valleys at

the foot of the Central Alps, especially those most distant from the

Adriatic coast.' This climate, our author tells us, cannot afford more

benefit to the consumptive than that of the fens of Lincolnshire, or

of the marshes of Holland. Brescia, Pavia, Mantua, and other Lombard

towns, also share in this character; and at Verona, Mr B. Honan

writes, that of all humbugs, the humbug of an Italian climate is the

most intolerable.

At Genoa, although the air is pure and transparent in fine weather, it

is liable to sudden gusts of wind and violent transitions dangerous to

the invalid.

'In no part of England could a climate be found more unfavourable for

consumptive invalids than that of Florence, a town built in a deep

ravine, almost surrounded by the Apennines, and intersected by a

squalid river.... Extreme cold in winter, great heat in summer, the

prevalence of the northerly winds, the chilling effects of which are

not always neutralised by the antagonistic winds, rapid and violent

transitions, profoundly affecting the system, even in healthy persons;

and combined with these violent atmospheric and thermal variations are

also, in similar proportions, hygrometric and electric ever-changing

influences.' Leghorn, the seaport of Tuscany, is built in a sunk

locality, in the midst of a marshy country. Beggars, galley-slaves,

assassins, smugglers, these are the picturesque portions of the

inhabitants; and the promenade is an arid beach, anything but soothing

to the respiratory organs. The English cemetery is a touching

spectacle, with its numerous monuments of brilliant marble; among

which stands conspicuous the tomb of Smollett.

Of Pisa, the grand central depôt of Italy for foreign consumptive

patients, Dr Burgess says: 'The excess of humidity and warm

temperature of the Pisan climate depress the vital force, induce an

overwhelming lassitude, and are, in my opinion, most unfavourable

elements in a climate so generally recommended for pulmonary

consumption. Whatever effect the humid mildness of the air may have in

diminishing excitability, and in allaying pulmonary irritation in

patients of a nervous temperament, it is decidedly injurious in those

of a feeble and lymphatic habit.... The delusion of an Italian

climate, as regards the cure or prophylaxis of tubercular consumption,

is in no part of that country, so delightful to persons in sound

health, more clearly portrayed than at far-famed Pisa. The stagnant

life, the death-like silence, the dreary solitude of this dull town,

whatever utility these elements may have in allaying the restless

irritability of nervous and excitable patients, always produce serious

evils upon those consumptive invalids of a melancholy turn of mind, or

whose spirit is broken by hope deferred. Brooding over their

melancholy condition, in a foreign land, away from the comforts of

home, without the solace and cheering influence of friends and

relations, they soon break down and perish.' M. Carrière and Sir James

Clark consider the climate of Rome adapted only for consumptive

patients in the first stage of the complaint; but Dr Burgess, after a

train of reasoning founded on scientific facts, comes to a conclusion

consonant with his own theory, that it is not adapted for consumption

in any stage or form whatever.

It is needless to follow our author to Naples, for this place is

admitted by all writers to be injurious in cases of pulmonary

consumption; but we may conclude this fragmentary survey by stating

that, according to Dr Burgess, the least injurious portions of Italy

are the Lake of Como and the city of Venice, _the air in neither of

them being warm, but in both equable_. Here we end as we began: 'It is

a mistake to suppose that a warm, humid, relaxing atmosphere can

benefit pulmonary disease. Cold, dry, and still air, appears a more

rational indication, especially for invalids born in temperate

regions.' It will be seen that our author differs occasionally from

both his great predecessors, Sir James Clark and M. Carrière; but even

in so doing, he has at least the merit of fairly opening out a most

important subject.

Let it be understood, that we have merely mentioned the nature of the

contents of this volume, without attempting to follow Dr Burgess

either in his reasonings or in the facts on which these are founded.

We have now only to recommend the work as one that will be found

highly interesting and suggestive, both by the medical and non-medical

reader.[3]
