14 | 8678 | NGC 5253 | 13 34 | -31.1 | 12 05 | 1 29 E | -31.1 | 12 16 | Dec 23 1895 | x 8678 As former plates of this region have an elongated image, probably due to atmospheric absorption as it is elongated both in R.A. & Dec., the load for this plate has been increased 1.4 grs. over ordinary sidereal load, and for the next plate (No. 8679) will be decreased by a like amount in order to overcome the elongation in R.A. on one of the plates as much as possible. The correct amount of increase or decrease as the case may be can then be determined. Plate C 8678 The images on this plate are double, but they seem to be more nearly circular than those on Plate C 8679. * Plates 8678 & 8679 are taken in slightly wrong R.A. Do not cover N.G.C. 5253.

14 | Dec 23 1895 | Only way I can account for this is that sidereal clock must have been out. I have sometimes found the one in the 11in dome to be as much as 5m slow. W. |
