For transits, the clock times of true transits are formed to May 13; the apparent right ascensions from observation to May 12; the star corrections are computed to May 20, and are applied to March 5. For the circle observations the concluded circle readings are completed to May zo; the apparent zenith distances to May 6; and the north polar distances from observation to April 1. The star corrections are computed to April t, but are not yet applied. The observations with tlie reflex zenith tube are reduced to May 19. With the altazimuth, the zenith distances are completely reduced to April 20, and the azimuths to Feb. 22; the' tabular compulations of zenith distance and azimuth are complete to March 17; and the errors of zenith distance and azimuth are converted into errors of R.A. and N.P.D. to the end of 1853. The results are very satisfactory. The observations with the double-image micrometer are fully reduced. For 1853, the means of the star-places in ledger are completely or very nearly finished, but the star-catalogue is not commenced. No effective work is done to the solar, lunar, and planetary reductions, beyond the formation of the separate errors in R.A. and N.P.D. As soon as the observations of 1853 shall be sufficiently reduced, I propose to prepare a new star-catalogue, based on the six years' observations from 1848 to 183. Printing of Astronomical Observations.--I stated in my last Report that the printing of the Observations for 1852 was scarcely commenced at the time of the last meeting of the visitors. For a long time the printing went on so slowly that I almost despaired of ever again seeing the Observations in a creditable state. After a most harassing correspondence, the printers were at length pe...
