...letter of Gordon Ferric Hull, professor emeritus of physics, Dartmouth College, which appeared in your July 28 issue, amazes...
Methylene blue and purple thionine looked promising. Whereas chlorophyll combines water and carbon dioxide into glucose in the presence of light, these pigments transform ferrous sulfate [Fe (SO4)] into ferric sulfate [Fe2 (SO4)3]. The ferrous compound consists of two "ions"-a positively charged iron atom linked with a negative sulfate unit. Under the influence of these pigments and light, the ions regroup themselves into the ferric form-two positive units linked with three negative units. And in the dark this reaction reverses itself. Regrouping of the ions upsets the electrical balance of the solution, creating electrical potentials...
...many attempted methods of using low-grade ore simple electrolysis proved best. Ore is dissolved in hydrochloric acid; the iron oxide dissolves to become ferric chloride; and when an electric current passes through the solution, the positively charged iron atoms migrate to the negative electrode. Advantage of electrolytic iron over smelted iron...

Strauss, W. Hallam Tuck, Allen Wardwell. - Lars Moen, an American chemist who was caught in Belgium by the Blitzkrieg, reported in his recent book Under the Iron Heel (Lippincott; $2.75) that scores of Belgians told him "perhaps the major" share of food sent from the U. S. to Belgium during World War I was diverted to feed the Germans...
