Also, a single hay fever antigen, such as feathers or some house or occupational dust, may be of a chronic perennial and non-seasonal character, or a succession of pollen antigens in some climates may produce more or less chronic symptoms. Positive skin tests for determining the allergic state are not immediately or invariably secured when reasonably expected. Children with chronic vasomotor rhinitis aften present the typical mouth breathing and facies ascribable to tonsillar and adenoidal hypertrophy, with failure of expected operative relief. Under certain conditions, the roentgenographic densities of vasomotor rhinitis can easily be mistaken for
