Another obvious thing in the epidemic of 1832 was that many of the first victims were among the destitute, drunken or reckless class. But there were innumerable exceptions, notably in Paris, where the multitude of victims included several peers, deputies, diplomatic personages and the prime minister.

One of the most striking things in the habits or preferences of cholera in 1832 was the early and unaccountable selection of the inmates of lunatic asylums, the fatuous paupers of workhouses, prisoners, or other immured persons badly housed and ill-fed. In most of these cases it was a mystery how the poison of cholera had got inside the walls. The earliest important instance was that of the Town Hospital or pauper infirmary of Glasgow. Other instances were the lunatic wards of Haslar Hospital, Hanwell asylum, Bethnal Green lunatic asylum, Lancaster county asylum, the Manchester New Bailey, situated in Salford, Coldbath Fields Prison, London, Clerkenwell workhouse (65 deaths), Bristol poorhouse (94 deaths). In the remote Westmoreland village of Hawkshead, thirteen miles from Kendal, cholera appeared unaccountably among the sixteen inmates of the poorhouse, attacking eight of them with sudden and severe symptoms so that four died; it was impossible to trace the introduction of the virus, but the poorhouse was nearly surrounded with stagnant water[1534].

Hardly anything was more keenly debated than the question as to how cholera spread. It was not difficult to find some instances of infection seemingly got from contact with living or dead cholera bodies: cases suggestive of that occurred at Sunderland at the outset, and later in Ireland more especially[1535]. In the Swan Street cholera hospital at Manchester, eight nurses took the infection, of whom four died. But on the whole the immunity of nurses (as in the Great Gorman Lane hospital of Dublin) and of medical men was remarkable. Although constantly in the presence of cholera patients, sometimes lingering over them, as in the operation of blood-letting, very few took the disease. In Manchester only one medical practitioner was known to have had an attack, a mild one. Gaulter says that Dr Alsop, of Birmingham, and Mr Keane, of Warrington, were the only two medical men known to him to have died of cholera in England; but two of the Bilston doctors died in the height of the epidemic there, one died at Musselburgh, seven at Sligo, and two at Enniskillen. The truth of the matter in cholera appeared to be the same as in plague and yellow fever, the two great infections that resembled cholera most closely as soil-poisons: namely, that contagion from the persons of the sick was a contingency, as Rush, of Philadelphia, had taught for yellow fever in the end of last century, and Blane had taught after him. A London writer stated this very fairly in 1832[1536]:

“I believe that this disease, like many other epidemic diseases, although communicable by miasma in the atmosphere, and originating or being producible from a peculiar state of that acting upon the earth, is sometimes contagious (or communicable from person to person) and sometimes not contagious. I believe the contagious nature of the disease depends: first, upon the number accumulated in one place, and the unhealthiness or ill-ventilated state of that place; or, in other words, upon the degree in which the miasma is condensed; secondly, upon the length of time a person remains exposed to the poison; third, upon the debility, or morbid irritability, and consequent susceptibility of the person’s frame, especially of the abdominal viscera.” The miasmata of an apartment, to be strong enough to become contagious, must arrive at a certain degree of concentration.

Cholera was, at all events, very different from typhus fever in the point of contagiousness: for in the epidemics of the latter many medical men fell victims, and the susceptibility to contagion was greater in proportion to the health and vigour of those who mixed with the sick.

It was well understood in 1832 that foul linen, bedding and clothes were a most certain means of carrying the poison, especially if they had been kept concealed for a time, or packed away in a chest or bundle. This was precisely the old experience of plague. The theory that the poison of cholera was conveyed in the drinking-water, of which illustrations were collected in 1849 and 1854, was not applied to any of the particular outbreaks in 1832. But one writer made a guess at it, assuming, as Snow did in 1849 and 1854, that the stomach and bowels were the organs by which the virus entered the system:

“From an attentive observation of the course this epidemic has taken in those places and countries which it has hitherto visited, I have been induced to draw the conclusion that a noxious matter or poison, being generated in the earth, has been diffused in the different springs in such situations [therefore he suggests the filtering of water through charcoal], and that this matter, being conveyed into the stomach with the fluid in question, produces that train of symptoms which, commencing in this organ, afterwards extends with more or less rapidity to the rest of the body[1537].”

In the treatment of cholera in 1832 many things were tried. The view taken of the pathology naturally determined the means of cure. To check the premonitory diarrhoea was seen to be of the first importance, and to that end laudanum or other form of opium was the familiar means. Lawrie, at Glasgow, found it most satisfactory, at a time when the profession in London were, as he says, denouncing it as a pernicious error. Towards the end of the epidemic in Dublin, Graves combined with the opium acetate of lead in large doses (a scruple of acetate of lead with a grain of opium, divided into twelve pills, one to be given every half-hour until the rice-water evacuations from the stomach and bowels began to diminish)[1538]. Some professed to find great benefit from blood-letting at a sufficiently early stage in the attack[1539]. The enormous drain of the fluids, leaving the blood thick or tarry, suggested to some that saline substances would be beneficial. The saline treatment was indeed the principal subject of writing during the year 1832. One way was to give saline drugs by the mouth; another way was to inject into a vein a large quantity of distilled water with some common salt and bicarbonate of soda dissolved in it, the vein at the bend of the elbow being usually chosen to operate on. Some were confident that they had saved lives in this manner, others were equally clear that salines were useless. One writer had abandoned salines by the mouth as a “most useless remedy,” while he had not lost faith in their intravenous injection, four having recovered out of twenty-three in which he had tried it. At length, however, the intravenous use of salines was abandoned also[1540].

It is well known that the greatest of all the lessons taught by cholera was the need of sanitary reform. The disease in its successive visitations so obviously sought out the spots of ground most befouled with excremental and other filth as to bring home to everyone the dangers of the casual disposal of town refuse. It was not until some years after the first visit of cholera that much was done in the way of extending the main drainage of towns, connecting the house-drainage systematically therewith, getting rid of open nuisances in back yards, and protecting the water-supplies from contamination. The Report of the Health of Towns Commission, 1844, was “the great magazine from which sanitary reformers drew their weapons[1541].” In the next few years an active school of sanitarians arose, including Sutherland of Liverpool, Grainger of London, and others. In 1848 was passed the first Public Health Act, administered by a Board of Health, of which Lord Shaftesbury was chairman, Chadwick and Southwood Smith members. London was excepted from the scope of the Act; but the City had a most vigorous medical officer in the person of John Simon, whose reports dealt with public sanitation on broad principles applicable to the capital and the whole kingdom. The movement in favour of sanitation, thus begun, received an irresistible impulse from the cholera of 1849, the lessons of which were as obvious as those of 1832.

The cholera which reached Orenburg in 1829 and Astrakhan in 1830 lingered in one part of Europe or another until 1837, Portugal and Spain having been its chief theatre in 1833, the south of France in 1834, Italy in 1835 and 1836, Austria, the Tyrol, Bavaria and (for the second time) Poland and the Baltic ports in 1837. In England, there was some revival of the seeds of it in 1833, as many as 1454 deaths being put down to Asiatic cholera in London from the 1st of August to the 7th of September. There was an undoubted epidemic of it at the fishing village of Ferryden, near Montrose, in June, 1833 (27 deaths during four weeks in a population of 700), the infection having been brought by one or more of the crew of the smack ‘Eagle’ from the Thames[1542]. In Glasgow a case occurred in Boar Head Close, High Street, on 30 May, 1833, which had the blueness, pinched face, whispering voice and cold clammy skin of Asiatic cholera[1543]. In Ireland there were a good many outbreaks in 1833, especially in villages or hamlets, and it is believed that these were renewed in 1834. But the most singular reappearance of cholera in the British Isles was in the month of December, 1837, some two months after it is believed to have ceased elsewhere in Europe. Outbreaks of true cholera in that month were observed at several places in the south of Ireland-around Bere Haven[1544], at Youghal, at Waterford, and at Dungarvan, where they went so far as to form a board of health[1545]. It was suspected to have been in Limehouse, on the Thames, in November. The most remarkable explosion of it was in the month of January following (1838) among the inmates of the Coventry House of Industry, of whom no fewer than 55 died in the course of four weeks—a mortality from choleraic disease that could hardly be explained on the hypothesis of cholera nostras even if the season had been the proper one[1546].
