Medicine: Capsules, Dec. 10, 1951

¶ Larry Jim Gross, son of an Air Force weatherman now stationed in Germany, was crippled by polio at 16 months. The National Foundation for Infantile Paralysis has paid for most of his long and costly care, including an operation to lengthen his left leg. Now Larry is repaying his debt by helping other polio victims: his picture has been chosen for the foundation's March of Dimes drive, which gets underway Jan. 2, Larry's seventh birthday. ¶ The National Research Council and the American Medical Association made it unanimous last week: they backed up the American Dental Association, agreed that the addition of fluorides to public water supplies is both safe and effective in checking tooth decay.
