Sec. 8. There are some Villages, in which, after the Curtain Lines are erased, watery marshy Places remain in the Room of them. The Effect of this is still more dangerous, because that putrify'd Water, which stagnates during the hot Season, suffers its Vapours to exhale more easily, and more abundantly, than that in the Curtain Lines did. Having set out for _Pully le Grand_, in 1759, on Account of an epidemical putrid Fever which raged there, I was sensible, on traversing the Village, of the Infection from those Marshes; nor could I doubt of their being the Cause of this Disease, as well as of another like it, which had prevailed there five Years before. In other Respects the Village is wholesomly situated. It were to be wished such Accidents were obviated by avoiding these stagnated Places; or, at least, by removing them and the Dunghils, as far as possible from the Spot, where we live and lodge. Sec. 9. To this Cause may also be added the Neglect of the Peasants to air their Lodgings. It is well known that too close an Air occasions the most perplexing malignant Fevers; and the poor Country People respire no other in their own Houses. Their Lodgings, which are very small, and which notwithstanding inclose, (both Day and Night) the Father, Mother, and seven or eight Children, besides some Animals, are never kept open during six Months in the Year, and very seldom during the other six. I have found the Air so bad in many of these Houses, that I am persuaded, if their Inhabitants did not often go out into the free open Air, they must all perish in a little Time. It is easy, however, to prevent all the Evils arising from this Source, by opening the Windows daily: so very practicable a Precaution must be followed with the happiest Consequences. Sec. 10. I consider Drunkenness as a sixth Cause, not indeed as producing epidemical Diseases, but which destroys, as it were, by Retail, at all times, and every where. The poor Wretches, who abandon themselves to it, are subject to frequent Inflammations of the Breast, and to Pleurisies, which often carry them off in the Flower of their Age. If they sometimes escape through these violent Maladies, they sink, a long Time before the ordinary Approach of old Age, into all its Infirmities, and especially into an Asthma, which terminates in a Dropsy of the Breast. Their Bodies, worn out by Excess, do not comply and concur, as they ought, with the Force or Operation of Remedies; and Diseases of Weakness, resulting from this Cause, are almost always incurable. It seems happy enough, that Society loses nothing in parting with these Subjects, who are a Dishonour to it; and whose brutal Souls are, in some Measure, dead, long before their Carcases.
