Ominous Arms Case

Introduces Mrs. Thompson, a tenant in the Ominous Arms Apartments, as she is suing her landlord, charging that her child's amoebic dysentery was the result of polluted water circulating in the building's faulty plumbing system. As various experts are on the witness stand they describe how water and milk supplies are guarded against pollution; then a hydraulic engineer demonstrates how back-siphonage takes place in a building and tells how it can be prevented.
