New observations in the UBV system of about twenty of the brighter stars in each of the nine E regions and three F regions have recently been made, primarily to check and revise the zero points of the magnitude sequences in those regions. The internal standard errors of the new E region zero points are + orn.0016 for V + 0m.0005 for B-V and 1 o ooo6 for U-B. The largest difference between the old and the new zero points is o oo8 (in U-B). The values of V and B-V in R. Obs. Bull. No. 49 also need corrections similar to those applied to Cape measures of bright stars included in R. Obs. Ann. No. 7. There are differences of zero point, amounting to 0m.01 for one of the F regions, and some differences of colour equation between the old and new series there. U-B has now been measured for more stars in these sequences. In all regions the new data appear to be more reliable than the old.
