It is to be remarked of the River water, that however pure the source, it contains germs of
vegetation and animalculae, and that to keep a butt or cistern unclean, uncovered, and in a
place near offensive matters, in stagnant air, or the water itself unchanged, the same will be
developed into most disgusting and unhealthy living forms, ready to produce or to favor me production
of peculiar diseases—The remedy is obvious.
