LUNAR TRANSITS ACROSS THE MERIDIAN OF HONGKONG.
The following transits of the moon were observed by eye and ear with TROUGHTON & SIMMS'S three inch transit instrument and the sidereal standard clock. The clock-correction was determined by aid of the Nautical Almanac apparent places of stars, and the right ascensions of the moon here exhibited are therefore subject to the corrections, which are applied to that catalogue. The first column shews the day of the month in Hongkong, the second the mean time, the third the limb of the moon, that was observed, the fourth the position of the instrument,-clamp east or west,-the fifth the mean of the seven wires, the sixth the reduction to the meridian, the seventh the clock-correction, the eighth the resulting right ascension, the ninth the seconds of right ascension in Nautical Almanac (to which Newcomb's corrections are now applied), the tenth the apparent error of Nautical Almanac in right ascension. From data exhibited in this column it appears that the semi-diameter in Hansen's lunar tables must be diminished by 0o. 127=1′′.905 in order to represent these observations. This correction was applied to the Nautical Almanac and the eleventh column exhibits then the error of the Nautical Almanac, the mean of which was + 0.091 + 1.365.--The longitude of the Observatory is 7 36 41.86 East.
