The author of This Chemical Age does another sound, dramatic popularization of chemistry, history, discovery, and development of vital products and synthetice for all phases of warfare. The new Canadian-discovered explosive which is 40% stronger than TNT: plastic for ship and plane building -- even for musical instruments: smokeless gunpowder: smoke screens: incendiaries: gases (for a game not worth the candle): the sulfa drugs against infection; serums and vaccines: plasma: atabrine: pyrethrum, the flun killer; rubber -- and the political bungle of huna: oil; dehydrated foods; nylon -- a wide range of things new and only half familiar. Incisive information on the great contributions of chemistry and blochemistry which will be of equal value in time of peace.
