Issue No. 19 of Ciba Review (Basle, March 1939), devoted to the history and economics of the commodity exchange or bourse, with particular reference to the wool and cotton trades. Charlotte Luetkens's articles cover the modern exchange, medieval markets and fairs as forerunners, the development of bourses in Antwerp, Amsterdam and London, and the history of speculation, including the tulip mania and the South Sea Bubble. Shorter pieces cover coffeehouses, Lloyd's, the guinea, whale fat and the word 'cotton', along with Scientific Notes and dye-industry advertisements and practical hints (combination shades, navy blues, acetate carbonisation, rust-spot removal). The issue is richly illustrated with engravings, paintings and photographs.
