It is a curious fact, that the French soldiers, who in 1848 made the siege of Rome, suffered no inconvenience or injury to their health from sleeping on the Campagna, and that, despite the prophecies to the contrary, very few cases of fever appeared, though the siege lasted during all the summer months. The reason of this is doubtless to be found in the fact that they were better clothed, better fed, and in every way more careful of themselves, than the _contadini_. Foreigners, too, who visit Rome, are very seldom attacked by intermittent fever; and it may truly be said, that, when they are, it is, for the most part, their own fault. There is generally the grossest inconsistency between their theories and their practice. Believing as they do that the least exposure will induce fever, they expose themselves with singular recklessness to the very causes of fever. After hurrying through the streets and getting into a violent perspiration, they plunge at once into some damp pit-like church or chill gallery, where the temperature is at least ten degrees lower than the outer air. The bald-headed, rosy John Bull, steaming with heat, doffs at once the hat which he wore in the street, and, of course, is astounded, if the result prove just what it would be anywhere else,--and if he take cold and get a fever, charges it to the climate, and not to his own stupidity and recklessness. Beside this, foreigners will always insist on carrying their home-habits with them wherever they go, and it is exceedingly difficult to persuade any one that he does not understand the climate better than the Italians themselves, whom he puts down as a poor set of timid ignoramuses. However, the longer one lives in Rome, the more he learns to value the Italian rules of health. There is probably no people so careful in these matters as the Italians, and especially the Romans. They understand their own climate, and they have a special dislike of death. In France and England suicides are very common; in Italy they are almost unknown. The American recklessness of life completely astounds the Italian. He enjoys life, studies every method to preserve it, and considers any one who risks it unnecessarily as simply a fool.
