While a great deal of factual information is presented, this reviewer wonders just how well it fulfills its intended function as a guide and help to parents of allergic children. It appears as too all-inclusive and comprehensive in its coverage for the average layman's use. So detailed and complete is the account of all the possible vagaries of clinical allergy that some parents would find it worrisome and their anxiety over this child's illness would be increased. The language is often technical and a good deal of theory is offered which may be interpreted by the reader as established fact. Human hair is mentioned as an allergenas is cane sugarand, says the authors, "it could almost be said that anything in the world might be at the bottom of an allergic condition."
