The charge-distributions of YuPr1-uBa2Cu3Ox with x approximate to 7 ar
e determined from the Rietveld-refined neutron scattering data of Neum
eier et al. using the bond-valance-sum method. Differences between the
se charge distributions and those proposed by the Charge-Transfer hypo
thesis and the Fehrenbacher-Rice model are pointed out.
