LOUIS, April 12. The living coBts will bo reduced by millions of dollars by chemical Invontltona and discoveries, today said delegates to the convention oC tho American Chemical society. In seeslon hore. Recent discovery by Fred G. Cottrell chief metallurgist ol the United States bureau or mines, of a lead, substitute in the manufacture of insecticides Is expected ex-pected to save millions of dollars of products and assist in lowering the cost, of these products.
