ASTRONOMY. 423 



l''qu;it()iial telescope of 4^ inches aperture, by Pike & Sons. 



Sextant, by Fauth & Co. 



The observatory was built as a working observatory for the college 

 students in astronomy, and it will be chiefly devoted to this purpose. 

 Besides this, the work for the following year will be, (1) to furnish the 

 city and surrounding towns with correct time signals; (2) to determine 

 the latitude and longitude; (3) to observe all occultations of stars that 

 are visible here. 



Cambrid(j€ [England) Ohservatory. — The total number of observations 

 made with the transit circle during the year was 3,253, including 2,442 

 observations of zone stars made on one hundred .nights. The observa- 

 tions of clock stars and those of Polaris are completely reduced, and 

 the mean places for January 1 obtained up to the end of 1884. The true 

 apparent places of all other stars observed in 1884 are also obtained, 

 both in R. A. and N. P. D. 



. CJtristiania. — An equatorial of 360'""' aperture and G-8'" focal length 

 lias been erected by Herr H. G. Olsen. {Sirius.) 



Cincinnati Ohservatory. — ]^o. 8 of the publications of this observatory, 

 «;outainiug the observations of comets in 1883, has ai^peared during the 

 j>ast year (1885). "It is noteworthy as presenting a ])retty complete 

 report on the phenomena of Pons' periodical comet. of 1812 at its reap- 

 pearauce. The features of the tail were particularly studied, and the 

 discussion of the observations, based upon the theory of Dr. Bredichin, 

 has been found to add confirmation to that theory." These observations 

 were made by Mr. H. C. Wilson while in temporary charge. The ob- 

 servatory is now under the direction of Prof. J. G. Porter. 



Constantinople. — It is rej)orted that the Sultan lias ordered the erec- 

 tion of an astronomical and meteorological observatory at Constantinople. 



Cordoba Observatory. — Dr. B. A. Gould returned to the United States 

 in April, 1885. He has been succeeded as director of the Cordoba Ob- 

 servatory by his first assistant. Dr. John M. Thome. Dr. Gould has 

 published as the final definitive position of the Cordoba meridian cir- 

 cle : Latitude, —31° 25' 15"-46 ; longitude, 4*' 16'" 48«-2 west of Greenwich. 



Dearborn Observatory. — Professor Hough's report for the year ending 

 May 20, 1885, states that the meridian circle has been used for deter- 

 mination of time, which is furnished daily to the city of Chicago. A 

 fall description is given of a i)rintiMg chronograph. The work with 

 the great equatorial has been confined mainly to difQcuit double stars 

 and the planet Jupiter, Four sketches of Jupiter accompany the re- 

 port. The partial eclipse of the sun of March 16 was observed for last 

 contact, and a number of dry-plate negatives were obtained. 



Benmore Observatory (1885). — Mr. W. H. Numsen lias erected a small 

 private observatory near the city of Baltimore, and his 4-inch Cooke 

 equatorial has been devoted to the study of the physical features of
