The plaques are stained thecolor of dahlia and can readily be counted. Rapid work, however,is essential, as the staining fluid soon attacks the red corpuscles. Ehrlich suggests the enumeration of the plaques in air-driedspecimens which have been stained with acid erythrosin. Owingto the relatively large amount of alkali which the plaques contain,they are stained an intense red with this reagent (see page 104). Rosin proposes that the air-dried specimens be fix
