POPULAR ERRORS ABOUT WATER.
Among the popular errors regarding drinking water is that which believes that an ordinary microscopc will show countless animalcules in our drinking fluid. This is an utterly erroneous idea. Ordinary water contains no animalcules, hut it may contain far more dangerous things in the shnpy of extremely minute disease gorms, sueh as require t.'ho highest powers of our best microscopes to discern. Thp.sc last arc our real enemies, because they are capublo of inflicting typhoid fever and other diseases upon us. To remove disease germs from infectcd water was formorly an impossibility, because common filters possess no such powers of preventing microbes from passing through them. Scienoe has evolved the "Berkefeld" Filters, which have been found to yield water absolutely free i'roni oil germ life. This power on the pnrt of tiio "Berkefelil" Filters is warranted by Dr. Sims Woodhead, Dr. Andrew Wilson, and other eminent scientists. They have experimented with these Filters, and have fully tested them. The filters are made suitable for the household, the camp, the factory, and the ship.
