The data are first given in fig. 12. The ordinates of the latter are in arbitrary units and must be divided by to reduce them to seconds of arc. In the continuous record from February 23 to March 13, the range of variation is almost as large as it was in fig. 9, showing that the use of jeweled bearings has.
