“The dysentery, or flux, so fatal to this worthy person, is commonly termed the country disease; and well it may, for it reigns nowhere so epidemically as in Ireland; tainting strangers as well as natives. But whether it proceeds from the peculiar disposition of the air, errour in diet, the laxity and waterishness of the meat, or some occult cause, no venomous creature living there to suck that which may be thought (in other countries) well distributed amongst reptilious animals, I shall not determine, though each of these circumstances may well conduce to its strength and vigour. Certain it is that regular diet preserves most from the violence, and many from the infection of this disease; yet as that which is thought very soveraign--I must say that the stronger cordial liquors (viz. brandy, usquebeh, treacle and Mithridate waters) are very proper, or the electuaries themselves, and the like[419].” From the Restoration to the Revolution little is known of epidemics in Ireland. It is probable that Dublin and the other considerable towns fared much the same as English towns. A Dublin physician writing to Robert Boyle on 27 February, 1682, speaks of a petechial fever, marked by leaping of the tendons, which had been fatal to very many in that city for these twelve or fourteen months[420]. With the Revolution the troubles of the country begin again, and enter on their peculiarly modern phase. For our history, two characteristic incidents come at the very beginning of the new period of disorder among the Irish--the sicknesses of the siege of Londonderry and the unparalleled havoc of disease among the troops of Schomberg in the camp of Dundalk. In both, the old “country disease,” which had affected Cromwell’s troops, was the primary malady, occurring, of course, in circumstances special enough to have bred it anywhere; in both, the dysentery was attended or followed by typhus fever, the old “Irish ague;” and although the epidemics of Londonderry and Dundalk in 1689 are properly examples of war sickness, yet the circumstances of each may help to realize the connexion between dysentery and typhus in the ordinary history of the Irish.
