Abstract
PARIS OBSERVATORY REPORT.—The annual report on the state of the Paris Observatory for the year 1891, presented by Admiral Mouchez, shows that a considerable amount of work, as in former years, has been accomplished during the past year. After mentioning briefly some of the last reports that have been communicated by those who are undertaking the work of photographically charting the heavens, he gives a résumé of the resolutions that have been adopted during the session of 1891. In the table showing the zones allotted to the different Observatories, that given to Greenwich lies between declinations + 90° and + 65°, and that to Oxford between + 31° and + 25°; the number of plates for each zone being 1149 and 1180 respectively. A resume of the meridional observations for the year informs us that no less than 19,458 observations were made, while those of the planets amounted to 570. M. Paul Henry, M. Wolf, and M. Deslandres, have all been busily engaged in their respective sections, their work having been previously mentioned in these columns. The second volume of the catalogue and the second volume of the observed positions (6h. to I2h.) have been completed and published; while Part III. (i2h. to 18h.)is still in preparation. The observations for 1884 are now quite finished, and those for 1885 will be ready by the end of this year. The verification of the reduction of the observations made in 1884-86 for the formation of a catalogue of twenty-four stars very near the Pole has already been commenced, and should, when completed, form a most important volume. The individual works that have been published from time to time are also referred to here. The meteorological observations and time service have been continued as usual.
