Corrections Spectrographic Determination of Trace Elements in lubricating Oils In the article on “Spectrographic Determination of Trace Elements in Lubricating oils” [.%SAL. (?mu.,2 5 , 151 (1953)] the gravimetric factor wae inadvertently used for converting chromium trioxide (CrOi) to chromium, rather than the factor for chromic oxide (Ci-20:). Thus the percentage of chromium in the master mixture shown in the first table in column 2, page 152, should be 7.14 rather than 5.43, R. F. MEEKER

Determination of Germanium In the art,icle on “Detcmnination of Germanium“ [ASAL. CHEII.,2 3 , 1023 (195l)l on page 102-2,line 6 in the paragraph on “Effect of Hydrogen Perozidc” should read: “1 mg. of hydrogen Hass.4 XEWCOVBE peroxide to 3 mg. of hem:ttoy-lin.”

In the paper “Fractionation of Baiiuni-Radium hliutures as Chromates by Precipitation from Homogeneous Solution“ [Salutsky, AI. L., Stites, J. G.. JI., and Martin, A. W.. AXAI, C m w , 2 5 , 1680 (1953)], Figures 2 and 3 were interchanged. The captions are correct as printed. The ordinate of Figure 2 i i Logarithmic Distribution Coefficient and the ordinate of Figure 3 is Limiting Distribution Coefficient.
