DISPOSAL OF WASTES LIABLE TO CONTAMINATE 179 Dilution is a great safeguard and so long as it is a million toone, will as a rule — to which there will always be exceptions— answer. Dilution as well as soil filtration — general seepage and per-colation of small wastes, farmyards, factories, gas washers —are helpful.

Theingestion of contaminating materials may be a cause of dys-pepsia or diarrhea, and probably also renders the system recep-tive to the invasion of the bacill
