rfiidiyo. 111., Dearborn Observatory, lat. +41 .">()' 

 1".0, lon^. 5* 50- 20'. 8 W. Founded by the Chicago 

 Astronomical Society in 1862-^53, and attached to the 

 University of Chicago. Principal instruments, .18}-in. 

 Clark equatorial, and 6-in. Repsold meridian circle. 

 The equatorial has been mainly devoted to double Mar 

 work by Burnham and Hough. With the meridian 

 circle, work was begun upon the Attronaniische (>< W/- 

 trhnfl zone, + 35 to + 40, but was not completed. 

 Since 1871 this instrument has been used for deter- 

 mining time for the city of Chicago. Directors : T. H. 

 Safford, 1805; E. Colbert, 1874; G. W. Hough, 1879. 



In 1888 the observatory was transferred to the 

 North-western University, and the instruments were 

 mounted in a new building at Evanston, 111., 16 miles 

 N. and 3 miles W. of the old site.

 4\'.'. } . W. The Cincinnati Observatory was founded in 

 1841-43 by the Cincinnati Astronomical Society, and 

 owes its existence to the energy and eloquence of I'rof. 

 O. M. Mitchel. A new building was erected in 1873 

 upon Mount Lookout, about 4 miles E. and 2 miles 

 8. of the central part of the city, the observatory 

 having become in 1872 a department of the University 

 of Cincinnati. The instruments are : an 1 1 J-in. equa- 

 torial made by Utachneidcr & Fraunhofer, finished by 

 Mcrz & Mahler, and objective refigured by Clark ; 

 4-in. equatorial, by Clark; 3-in. transit, by Buff & 

 Bcrger ; clocks, chronometer, chronograph, etc. ; a 

 . r >i-in. meridian circle, by Fauth. was added to the 



Suipmentin 188H. Directors: 0. M. Mitchel, !s-2;

 O. Stone, 1875; .1. O. Porter, 1884. Observations 

 of double stars and comets made with the equatorial 

 and a zone-catalogue observed with the transit have 

 filled nine numbers of l*nl>liait!ara.
