the epidemic of 1817, and about 10,000 in that of 1837, and not only the number of persons attacked but the violence of the disease increased with each repetition. {100a}
But the fury of the epidemic in all former periods seems to have been child's play in comparison with its ravages after the crisis of 1842. One- sixth of the whole indigent population of Scotland was seized by the fever, and the infection was carried by wandering beggars with fearful rapidity from one locality to another. It did not reach the middle and upper classes of the population, yet in two months there were more fever cases than in twelve years before. In Glasgow, twelve per cent. of the population were seized in the year 1843; 32,000 persons, of whom thirty- two per cent. perished, while this mortality in Manchester and Liverpool does not ordinarily exceed eight per cent. The illness reached a crisis on the seventh and fifteenth days; on the latter, the patient usually became yellow, which our authority {100b} regards as an indication that the cause of the malady was to be sought in mental excitement and anxiety. In Ireland, too, these fever epidemics have become domesticated. During twenty-one months of the years 1817-1818, 39,000 fever patients passed through the Dublin hospital; and in a more recent year, according to Sheriff Alison, {100c} 60,000. In Cork the fever hospital received one-seventh of the population in 1817-1818, in Limerick in the same time one-fourth, and in the bad quarter of Waterford, nineteen-twentieths of the whole population were ill of the fever at one time.
When one remembers under what conditions the working-people live, when one thinks how crowded their dwellings are, how every nook and corner swarms with human beings, how sick and well sleep in the same room, in the same bed, the only wonder is that a contagious disease like this fever does not spread yet farther. And when one reflects how little medical assistance the sick have at command, how many are without any medical advice whatsoever, and ignorant of the most ordinary precautionary measures, the mortality seems actually small. Dr. Alison, who has made a careful study of this disease, attributes it directly to the want and the wretched condition of the poor, as in the report already quoted. He asserts that privations and the insufficient satisfaction of vital needs are what prepare the frame for contagion and make the epidemic widespread and terrible. He proves that a period of privation, a commercial crisis or a bad harvest, has each time produced the typhus epidemic in Ireland as in Scotland, and that the fury of the plague has fallen almost exclusively on the working-class. It is a noteworthy fact, that according to his testimony, the majority of persons who perish by typhus are fathers of families, precisely the persons who can least be spared by those dependent upon them; and several Irish physicians whom he quotes bear the same testimony.
