contagion; the contagion came from direct contact with the crowds of starving poor, their clothes ragged and filthy, their bodies unwashed, and many of them suffering from dysentery. The greater fatality of fever among the richer classes had been a commonplace in Ireland since the epidemic of 1799-1801, and is remarked by the best writers[518]. At Loughrea, in Galway, Dr Lynch observed that “in the year 1840 the type of fever was very bad indeed, and very many of the gentry were cut off by it.” He reckoned that ordinarily one in six cases of fever among the richer class proved fatal, one in fifteen among the poor[519]. But in the great famine, six years after, the fever of the poor assumed the still milder type of relapsing, fatal perhaps to one in a hundred cases, or three in a hundred, while the fever which contact with them gave to those at the other extreme of well-being became a peculiarly malignant typhus, fatal to six or seven in ten cases, as Dr Pemberton of Ballinrobe found, or to three or four in ten cases, as many others found. Of course it was the peasantry who made up by far the greater part of the mortality in the years of famine; but they were cut off by various maladies, nondescript or definite, while the richer classes died, in connexion with the famine, of contagious typhus and here or there of contagious dysentery. Even in the crowded workhouses and gaols, more deaths occurred from dysentery than from fever. But in some of the gaols great epidemics arose which cut off many of the poor by malignant infection. That was an old experience of the gaols, studied best in England in the 18th century; the worst fevers, or those most rapidly fatal, were caught by the prisoners newly brought to mix with others long habituated to their miserable condition. The gaols in Ireland during the famine were crowded to excess, not so much because the people gave way to lawlessness--their patience and obedience were matters of common complimentary remark--but because they committed petty thefts, broke windows, or the like, in order to obtain the shelter and rations of prisoners. The mortality in the gaols rose and fell as follows[520]: Year Deaths in gaol 1846 130 1847 1320 1848 1292 1849 1406 1850 692 1851 197
