160 ASTRONOMY FOR 1889, 1890. 



Algiers : Trepied. — A meridian circle of O'^.IO (7.5 inches) and an 

 eqiiatoriul of 0™.12 (4.7 inches) have been added to the equipment. Ob- 

 servations hav'i been made \\\)0\\ a catalogue of 10,000 stars in the zone 

 _ ISO to — 13.3°. It is expected that the photographic equatorial will 

 soon be installed. (1889.) 



Armagh: Breyvr. — Observations of nebuhe and physical observations 

 of Jupiter and Saturn; time service. 



Basel: Ri/fgeiibacli. — Devoted entirely to the instruction of students. 



Berlin : W. Foerster. — Observations with the transit circle, obser- 

 vations with the 9-inch equatorial of asteroids, comets, and double stars, 

 and with the small transit of comparison stars and stars occulted by 

 the moon. 



BESANgoN: (rr/te;/.-— Observations of comets; horology. The observ- 

 atory possesses an equatorial coude. 



Birr Castle : Lorel Rosse. — Preparing for publication a series of 

 sketches of the milky way; measures of lunar heat during the eclipse of 

 January 28, 1888, have been reduced. 



Bonn : ISehdnfeld— Zone, observations +10° to +50° with the transit 

 circle. Reductions in a forward state. (1889.) 



Bordeaux: /^rM/ef.— Preparations are being made for observing the 

 zone — 20'^ to — 2.jO. The photographic equatorial has been mounted. 

 (1889.) 



Breslau: Galle. — Chiefly magnetic and meteorological work. Small 

 transit used for time service. 



Cambridge (England): Adams. — Mr. Newall has presented his 

 25-inch refractor to the university observatory, and the university 

 authorities have voted to spend about $11,000 on its installation near 

 the present observatory, and to appoint an observer, at $1,200 per 

 annum, to devote himself to research in stellar physics. It is under- 

 stood that the work with this instrument will be under the charge of 

 Mr. H. F. Newall. 



Volume 23 of the publications has been issued and deals with the 

 observations from 18(56 to 1809. 



Camden. — The amateur astronomical society at Camden, New Jer- 

 sey, has a small observatory, with 5i-inch equatorial, transit instru- 

 ment, chronograph, clock, etc. 



Cape of Good Hope: Gill.— With the meridian circle regular ob- 

 servations have been made of the sun, Mercury, Venus, comparison 

 stars, stars occulted by the moon, etc. The heliometer has been con- 

 stantly in use and much attention has been given to astronomical pho- 

 tography. Prof. J. C. Kapteyn has measured definitively 389 negatives 

 of the plates of the southern photographic Durchmusterung, covering 

 8,769 square degrees of the sky. This work represents 489,490 obser- 

 vations of about 193,000 stars, or about 63 i)er cent, of the whole work.
