working class as a whole, and not merely a certain number of individuals in it, was drunken, thriftless and slothful. The familiar proof of this is the apathy of the Church, broken by the Methodist revival of religion. The epidemic fevers of 1718-19. In the fifty years from 1715 to 1765, the three worst periods of epidemic fever in England and Scotland correspond closely to the three periods of actual famine and its attendant train of sicknesses in Ireland, namely, the years 1718-19, 1727-29, and 1740-42. The three divisions of the kingdom suffered in common, Ireland suffering most. The first period, 1718-19, was an extremely slack tide in medical writing, insomuch that hardly any accounts of the reigning maladies remain, except those by Wintringham, of York, and Rogers, of Cork. The whole of the Irish history of fevers and the allied maladies is dealt with in a chapter apart. Of the Scots history, little is known for the first of the three periods beyond a statement that there was a malignant fever and dysentery in Lorn, Argyllshire, in January and February, 1717[99]. Wintringham gives the following account of the _synochus_, afterwards called typhus, which attracted notice in the summer of 1718 and became more common in the warm season of 1719: in each year it began about May, reached its height in July and lasted all August, carrying off many of those who fell into it. It began with rigors, nausea and bilious vomiting, followed by alternate heats and chills, with great lassitude and a feeling of heaviness: then thirst and pungent heat, a dry and brown tongue, sometimes black. The patient slept little, did not sweat, and was mostly delirious, or anxious and restless, tossing continually in bed. About the 12th day it was not unusual for profuse and exhausting diarrhœa to come on. In a favourable case the fever ended in a crisis of sweating about the 16th day. Those who were of lax habit, unhealthy, hysteric, or cachectic, were apt to have tremors, spasms and delirium, while others were so prostrated as to have no control over their evacuations, lying in a stupor and raving when roused out of it. In these the fever would continue to the 20th day; in some few it ended without a manifest crisis, and with a slow convalescence[100]. This applies to the city of York, but in what special circumstances we are not told. However, it happens that a physician of York, two generations after, in giving an account of the great improvement that had taken place in its public health, throws some light on its old-world state: “The streets have been widened in many places by taking down a number of old houses built in such a manner as almost to meet in the upper stories, by which the sun and air were almost excluded in the streets and inferior apartments[101].”
