CHAP. II. Of the Waters.
1. THe learned, and therefore truly Noble Philosopher, my Lord Viscount St. Albans, in his History of Life and Death, or prolongation of Life; as well considering the consumption of the body of Man, as reparation of it; the one being as much to be prevented, as the other promoted; in the for∣mer of these makes the ambient Air of eminent concern; some sorts of it being as predatory and wastful of the body, as others again are comfortable and refreshing: Whence it is that Persons of plentiful Estates, that have (as we say) the world at will, and are not tyed to a single Seat; either build or make choise of one for their most common residence, that is situat in a good and whol∣some Air: where by Air they intend not the simple Element of the Ancients, for in this sense all Air (if there be any such thing) is equally pure; but that somwhat grosser substance that immediat∣ly incompasses the terraqueous Globe, wherein we daily breath, live, and have our being; which is commonly fill'd with all sorts of Exhalations, and is comparatively good or bad, healthy or other∣wise; as it partakes more or less, of wholsome or noxious, vapors or fumes; exhaled either from quick liveing streams, or stagnant pooles and uliginous boggs; from dry wholsome Soils, or mineral Earths. Which seeming indeed the more immediat causes of sickness or health than the pure Air, that being only the vehicle of diseases, and not fundamentally good or bad, but by partici∣pation, as was hinted in Oxfordshirea 1.1; 'tis plain that the consi∣deration of the health of this County, rather belongs to this place, and the following Chapter, than to the former of Air.
2. But that the Reader may not only be amused with generalls, let us treat of this matter more distinctly than usual, and strictly examin whether this Air we breath in, do indeed so much affect the body of Man as is commonly pretended; and if so, which it is that comforteth and conserveth it most, and which most preyeth upon it, so as to hasten its consumption; that certainly being to be esteemed the most healthy, that prolongeth; and that the most unhealthy, that abridgeth its duration: Wherein I shall not need to trouble the Reader with any of the nice Experiments of the Air-Pump, whereof some not unfitly might have been reduced to this
