• The fine structures of X-ray K absorption spectra of nickel in metallic nickel, NiO, Ni_2O_3 and NiO_2・nH_2O were photographed by a bent crystal spectrograph. The fine structures of absorption spectra of metallic nickel and NiO agree well with those published by previous authors, but those of Ni_2O_3 do not coincide with those reported by Hayasi and Cauchois. Also Cauchois' data of Ni_2O_3 do not coincide with Hayasi's data. This seems to be due to doubtful chemical structures of Ni_2O_3 and it is supposed that the three specimens used by the three authors might have different chemical structures. The first absorption maxima A are much more pronounced with increasing oxygen proportion and the general features of α, β, C and γ of the absorption spectra of oxides are similar respectively. However, the second small absorption maxima B are less pronounced with increasing oxygen proportion. These facts are expected from Coster and Kiestra's and Cauchois' considerations. It may be considered from the comparison of the present curves of absorption spectra only that nickel sesquioxide is a mixture of NiO and NiO_2・nH_2O.
