Z. D. 30 47 40 | 15·8 | 44 | | 34 4 49 | 34 4 49 | In observations with the sextant the stars have been invariably taken on the meridian. In observations with the theodolite the stars have been taken on the meridian except where an asterisk has been affixed to the name of the star (in column 6). Where this occurs the numbers in the column of Remarks are the computed means of the true local times of observation used in the computation for latitude. The numbers in brackets in columns 7, 10, and 11, denote the number of pairs (face left and face right) of observations taken. The corresponding figures in column 7 give the corrected mean zenith distance.
