CITY (Cyd.) — It has been obferved that large cities are more liable than other places to peftilential and putrid diforders, which is owing to the flagnation and corruption of the air. This is always the cafe in thofe which are low and unpro- vided with common fewers; where the ftreets are narrow and foul, the houfes dirty, water fcarce, and jails and hofpitals crowded : alfo when in fickly times the burials are within the walls, or when dead animals and offals are left to rot in the kennels or on dunghills; when drains are not provided to carry off" any large body of ftagnating water in the neighbourhood; when flefh-meats make the greater!, part of the diet, with- out a proper mixture of greens, bread, wine, or fermented liquors; from the ufe of old mouldy grain. In proportion to the number of thefe and the like caufes concurring, a dty will bemoreorlefs fubjecr. to peflilential difeafes, or to receive the leaven of the true plague brought into it by any merchandize.

However, as great cities furnifii many materials for vitiating
the air, they likewife afford two considerable antidotes; the iirfl arifes from the circulation of the air, by means of the conftant motion of people and carriages, and of the draughts made by fires : the other depends on the great quantity of an acid produced by fuel, the flrongefl: refifter of putrefaction.
