Abstract The paper describes and evaluates a capillary-tube technic for the chamber count of circulating eosinophils. The outstaning merits of the method are ease of collection, accuracy ard reproducibility of results and the fact that counting can be deferred for hours and even days without vitiation of the accuracy. Application of this method to study of normal subjects indicates a diurnal cycle of eosinophil fluctuation, with a low at noon and a high late at night.
