The nucleated erythrocytes of Amphiuma, Necturus, Rana pipiens, Rana catesbeiana, Siredon, and Gallus were exposed to a series of aldehyde-coupling reactions. The degree of coupling was indicated by subsequent blocking of Feulgen coloration measured visually and photometrically. Characteristic variation from species to species of the inhibition of Feulgen coloration was observed. These differences are interpreted as qualitative differences in the reactivity of the DNA complexes in the species studied.
