1. The DNAs of human spleen and of human placenta were partially degraded with acids and the products were compared with one another.
2. No discrepancy was found in most respects between the corre-sponding degradation products of the DNAs, but two products from the placental DNA rotate D-light more to the right than the corresponding products from the other DNA, which is opposite to the relationship between the DNAs themselves.
3. The DNAs are fairly stable to acids after elimination of purines.
4. Thus it has been found that the placental DNA differs from the splenic DNA in mutual linkage of the components in the pyrimidinenucleic acid moiety.
