tor, six titular astronomers, ten adjunct astronomers, and a 

 certain number of assistant astronomers, together with a sec- 

 retary and a financial agent. The general operations of the 

 observatory, however, are to be controlled by a scientific 

 council, consisting of the director, certain chief astronomers, 

 and six counselors of the observatory chosen among the sa- 

 vants eminent for their labors in mathematical, astronomical, 

 and physical science, and four of them, at least, to belong to 

 the Academy of Sciences or to the Bureau of Longitudes. 

 Each year one of these goes out of office, but may be rechosen 

 by the minister. The higher officers of the observatory are 

 to be appointed by the President of the republic, on the nom- 

 ination of the minister and with the advice of the General 

 Assembly; the lower grades are appointed by the minister, 

 on the nomination of the director. 



The annual salaries of the titular astronomers vary from 

 six to eight thousand, francs, those of the adjunct astronomers 

 from thirty-five hundred to six thousand, and of the assist- 

 ants from one thousand to thirty-five hundred. The person- 

 nel of the Observatory of Paris is named in the decree of the 

 same date. Professor LeVerrier being again placed at the head. 

 His functions, however, as far as concerns the control of the 

 force, are limited, and largely dependent upon the consent of 

 the council of the observatory. M. Stephan is named as di- 

 rector at Marseilles, and M. Marie-Davy director of the Mete- 

 orological Observatory at Montsouris. 3 ^, February 20,

THE CINCINNATI OBSERVATORY. 



The Cincinnati Observatory, founded by Professor O. M. 

 Mitchell, is, we learn, to be removed, and established in a 

 manner Avorthy the wealth of Cincinnati. From the draw- 

 ings that we have been permitted to see, it may be judged 

 that the dome of the new building will be thirty-five feet in 

 diameter in the inside, or the largest in the world. Of course 

 such a structure will be too expensive to be made a play- 

 thing ; and, if the telescope be proportionately large, Cincin- 

 nati may yet rival Washington in its superiority. 



We understand from Professor Abbe, of the Weather Bu- 

 reau of the Army Signal-office, who, it will be remembered, 

 continued until lately to be the director of the observatory
