From 1851 to 1854, the medical journal The Lancet convened an Analytical Sanitary Commission to investigate the problem of adulteration of food. The adulteration of coffee by admixture of chicory was one of the issues addressed; Arthur Hill Hassall, with the assistance of Henry Letheby, conducted analyses of various commercial products, and the results were published in The Lancet. John Lindley, Sir William Jackson Hooker, William Benjamin Carpenter, and others were asked to carry out independent tests, and their reports are bound in this volume of the Botanical Tracts.
