Bernabo's example was imitated; nor was there any century more appropriate for recommending to governments strong regulations against the plague that the fourteenth; for when it broke out in Italy, in the year 1399, and still demanded new victims, it was for the sixteenth time, without reckoning frequent visitations of measles and small-pox. In this same year, Viscount John, in milder terms than his predecessor, ordered that no stranger should be admitted from infected places, and that the city gates should be strictly guarded. Infected houses were to be ventilated for at least eight or ten days, and purified from noxious vapours by fires, and by fumigations with balsamic and aromatic substances. Straw, rags, and the like were to be burned; and the bedsteads which had been used, set out for four days in the rain or the sunshine, so that by means of the one or the other, the morbific vapour might be destroyed. No one was to venture to make use of clothes or beds out of infected dwellings unless they had been previously washed and dried either at the fire or in the sun. People were, likewise, to avoid, as long as possible, occupying houses which had been frequented by plague- patients. We cannot precisely perceive in these an advance towards general regulations; and perhaps people were convinced of the insurmountable impediments which opposed the separation of open inland countries, where bodies of people connected together could not be brought, even by the most obdurate severity, to renounce the habit of profitable intercourse. Doubtless it is nature which has done the most to banish the Oriental plague from western Europe, where the increasing cultivation of the earth, and the advancing order in civilised society, have prevented it from remaining domesticated, which it most probably was in the more ancient times.
