9. As stated in the "Instructions for making Meteorological Observations, etc," meteorological instruments forwarded by observers, who regularly send their registers to the Observatory, are verified here free of cost. During the past year 7 aneroids and 2 thermometers were verified. In addition, several hundred barometers and aneroids on board ship were compared with our standard.
10. Professor HECKER of the International Geodetic Institute, Potsdam, visited the Observatory for the purpose of making an accurate determination of the constant of gravity, remaining from November 9th to November 25th. magnetic hut was placed at his disposal for this work.
The
11. In 1904 the number of transits observed was 1,411. The axis of the transit instrument was levelled 262 times, and the azimuth and collimation errors, which are less liable to variation, were determined 17 times by aid of the meridian mark. These observations have been made either by Mr. PLUMMER or by myself, and have been already printed in the "Observations made in 1903." All the transits of southern stars have been reduced and a very accurate catalogue of right-ascensions of southern stars has been printed as an appendix to "Observations made in 1903." They are so distributed as to afford a star every minute for determining the time, and the proper motions of these stars have also been deter-
