The work fell into two parts: a study in the National Children's Home, Harpenden, of the four methods under review, and a study of the diets of schoolchildren in Ealing by weighing and questioning. One of us (E.R.B.) was responsible for the field work of the inquiry, 'while two of us (C.G.D., J.K.) were responsible for the chemical analyses of the diets collected in the National Children's Home, Harpenden.
