Fever and dysentery decreased to an ordinary level in 1823, but rose somewhat again in 1824, the summer of which was hot and moist. But it was in the hot and dry summers of 1825 and 1826 that dysentery became notably common in Ireland generally and in Dublin in particular. It began in the capital in June—among the richer class of people. About the middle of August admissions for dysentery were perceptibly raising the number of patients in the Cork Street Fever Hospital, and continued to do so throughout the autumn. At one dispensary three out of four applicants had dysentery. All those admitted to hospital were over twenty years of age; of thirty-five cases under Dr O’Brien, nine died, all of which had ulceration of the great intestine, in one case gangrenous. The mortality was not nearly so great among the richer classes, in which respect dysentery reversed the rule of typhus fever. O’Brien had one obvious case illustrating the curious connexion between dysentery and rheumatic fever, originally remarked by English observers in the 18th century. A hospital porter was admitted with “fever of a mixed catarrhal and rheumatic type.” Having been blooded and subjected to free evacuations, his fever left him on the fourth day, but he was at once seized with dysentery, which ran its course[482].
It is to be noted that this epidemic of dysentery began in Dublin in the hot June weather of 1825 among the richer classes, and that there was no notable increase of fever while it lasted. It appears to have declined in Dublin in the early part of 1826. After a cold and dry spring there began one of the hottest and driest summers on record. The first rain for four months fell on the 15th of July, 1826, the thermometer rose as high as 86°, and was on a mean several degrees above summer temperature in Dublin. In the spring labour had become slack, and before long it was estimated that 20,000 artizans in the Liberties (weavers and others) were out of work. Early in May there began a most extraordinary epidemic of relapsing fever, with which some typhus was mixed. By the 9th of May, the 220 beds of the Cork Street Hospital were full, and applicants were sent away daily. On 4 August, a temporary hospital of 240 beds was opened in the garden of the Meath Hospital; on the 18th, the Wellesley Hospital, in North King Street, was opened with 113 beds; on the 15th, tents to hold 180 patients were erected on the lawn of the Cork Street Hospital, raising its accommodation to 400; a warehouse in Kevin Street was furnished with beds for 230 patients, and some increase was made to the beds in Sir Patrick Dun’s and Stevens’s Hospitals. The whole number of fever-beds in Dublin hospitals at length reached 1400; but not half the number of cases was provided for. At a meeting in the Mansion House on 26 October, it was stated that there were at that date 3200 persons sick of the fever at their homes, besides the 1400 in the hospitals. Funds were subscribed, soup-kitchens and dispensaries opened in various districts of Dublin, and kept open most of the winter, “but they made little impression on the epidemic, which continued with unabated violence.” In March, 1827, it began suddenly to decline, and fell rapidly until it was nearly extinct in May; and that, too, although “the complaints of distress and want are to the full as loud as at the commencement of the epidemic, and provisions are dearer[483].” The corresponding sicknesses in Edinburgh and Glasgow were later—the fever chiefly in 1828, the dysentery in 1827 and 1828.
This great epidemic was mainly one of relapsing fever. The patient “got the cool,” or passed the crisis of the fever, usually on the evening of the fifth or seventh day, sometimes on the ninth, the evening exacerbation, which was to prove critical, being ushered in generally with a rigor, and passing off in profuse perspiration throughout the night. The five-day fever was more certain to relapse than that of seven days, the seven-day fever was more likely to relapse than that of nine days. The relapses might be one or two or three or more, prolonging the illness for weeks. The clear interval varied from twenty-four hours to fourteen days. There were some cases with jaundice which led Stokes and Graves to speak loosely of “yellow fever[484].” O’Brien saw only four cases with exquisite icterus in fifteen hundred cases of relapsing fever. There was a small proportion of cases of ordinary typhus of a severe kind, marked by unusual delirium or phrensy and the absence of sordes on the teeth or petechiae on the skin; the typhus cases became more numerous in the winter season, or, in other words, the original attack lasted to nine, eleven, or thirteen days, with little or no tendency to relapse. Gangrene was not uncommon in one part of the body or another, and in four cases the feet became gangrenous[485].
Even with the admixture of pure typhus cases, and with dysenteric complications in the autumn and winter, the mortality of the whole epidemic was small—not more than it would have been among a third part the number of fever cases in an ordinary year. At the Cork Street Hospital alone (including the tents) there were 8453 admissions from 4th August, 1826, to 4th April, 1827, with 332 deaths, or four deaths in a hundred cases. The proportion of recoveries was quite as remarkable in known instances in the squalid homes of the poor, where two or three would be found ill of fever on one pallet, or a father and six children in one room, shunned by the neighbours.
The strangest thing in this epidemic was the sequel of it. In the spring of 1827, intermittent fever, which had not made its appearance for several years in Dublin, began to prevail pretty generally; whilst the ordinary continued fever showed a strong tendency to assume the intermittent and remittent forms. It is not surprising, therefore, that Dr O’Brien, who had these varied experiences of epidemic dysentery in 1825, of epidemic relapsing fever and typhus in 1826, and of intermittent fever in 1827, should adopt Sydenham’s language of epidemic constitutions, and revert to the old Sydenhamian doctrine of causes. While the sequence of epidemic diseases in Dublin was some dysentery in the autumn and winter of 1825 and relapsing fever on a vast scale during the excessively dry spring and summer of 1826, in country districts of Ireland, such as Skibbereen, dysentery became epidemic after the great drought and heat of 1826, while “fever disappeared altogether,” and indeed all other prevalent forms of sickness gave way before it, so general was it. Such is the report from Skibbereen, county Cork, a district that became early notorious, in the great famine of 1846-47, and was perhaps a kind of barometer of Irish distress twenty years earlier. The epidemic dysentery of 1826 attacked all classes there, but chiefly the poorest; it was apt to begin insidiously, and, as it was often neglected, so it often became obstinate and hard to cure. Dr McCarthy attributed it to the drought of 1826, the commercial distress of 1825, the lack of employment for labourers, the overgrowth of population, and the alarming rise in the prices of food[486]. He uses the same economic illustrations as O’Connell and Smith O’Brien in the Great Famine twenty years after, which were, indeed, as old as the time of Bishop Berkeley[487].
Although little is heard of the fever of 1826-27 except in Dublin, it is probable that the same causes which produced it there were operative in other large towns. The admissions to the Limerick Fever Hospital rose rapidly in the end of 1826. Geary, who was appointed one of its physicians that year, estimates that about one in twelve of the population of Limerick (63,310) were treated for fever in 1827 at public institutions, besides those treated in private practice. It was relapsing fever, as in Dublin[488].
Perennial Distress and Fever.
According to all the figures of Irish fever-hospitals, and the generalities of their physicians, fever was now constantly present in the towns. After the relapsing epidemic of 1826-27 had subsided, there was no rise above the steady level until the years 1831 and 1832, when a considerable increase appears in the admissions to the hospitals of Dublin, Limerick and Belfast. But the fever of 1831-32 was totally eclipsed by the cholera, and little is heard of typhus in Irish writings until 1835-36, when an epidemic arose, purely of typhus fever, which is said to have been as severe upon some districts as that of 1817-18 had been. This outbreak fell at the time of the Commission presided over by the Earl of Devon, the report of which is authoritative for the state of the Irish lower class and the causes of the same. The country cottiers and the poor of the towns were always on the verge of starvation. Dr Geary, of Limerick, in 1836 estimated as follows the proportion of poor to the whole population, “the poor” being taken to mean “those who would require aid if a Poor Law existed[489]:”
