.192 SCIENTIFIC RECORD FOR 1884. 



VI. 919 observations of 26 ciicumpolar pairs. 



In all 7,542 measures. 



Vol. II will contain 13,800 measures of W. Struve's Dorpat catalogue. 



Munich. — The repairs are nearly completed. Among the 37,000 stars 

 whose places have been fixed at Munich, some 9,000 have been only 

 once observed, and are in no other catalogue. These are to be each 

 once observed. 



The Munich Zones are being completely re-reduced and brought up 

 to 1880.0 with comparisons with Lalaude, Bessel, Santini, Ruemker, 

 Schellerup, Copeland, and Argelander. 



O^Gyalla. — Stars are spectroscopically observed in the Zone O^to — 15°. 

 These observations include stars to 7 magnitude, and each star is ob- 

 served twice. Special star spectra are more carefully investigated. 

 Comet spectra have also been regularly observed. The color of all stars 

 to 4 magnitude, inclusive, are observed with a Zoellner's colorimeter. 

 The Svn was regularly observed (on 203 days). Many other investiga- 

 tions are also in progress, for an account of which reference must be 

 made to the original report. 



Padua. — The work of the observatory is intimately connected with 

 that of the Italian Geodetic Commission. 



The Observatory of Paris. — Admiral Mouchez's report on the state of 

 this establishment and the work accomplished therein during the past 

 year, commences with some details of his scheme for erecting a succur- 

 sal observatory at a distance from Paris, where the disadvantages of 

 location in the midst of a great city would be avoided. His proposal 

 was to dispose of a part of the actual grounds of the observatory, a step 

 which would be likely to realize a sum adequate to the erection of the 

 new building, at the same time retaining the present one to form the 

 headquarters of tne bureau des calculs, the archives, and the museum, 

 the two establishments to remain under the same direction and to con- 

 stitute together the Observatory of Paris. This scheme, it is, known, 

 has not met with general acceptance at the hands of the scientific au- 

 thorities. 



M. Lcewy, in charge of the meridian service, has been occupied with 

 the reobservation of stars in the catalogue of Lalaude, while a large 

 number of observations of the sun, moon, and planets has also been 

 made, eighteen observers taking part in this work in the course of the 

 year. The eqiiatorials of 12 and 14 inches aperture and the equatorial 

 coudc were employed on observations of comets and small planets. The 

 Ecliptical Charts Kos. 12, 19, 48, and 67, have progressed, and attention 

 has been paid to double-star measures. M. Mouchez reports that the 

 construction and installation of the great telescope (0"^74.) has been 

 retarded by the difficulty of establishing it in the grounds of the observa- 

 tory at Paris. In the department of astronomical physics, MM. Thol- 

 lon and Tr^picd had been oi'cu]iied for six weeks on the Pic du Midi, 

 where, with M. Naussinat, in j^reseut charge of the observatory, they
