ASTRONOMY FOR 1889, 1890. 163 



for four years, aud is now iu Peru ijhotograpbing^ the southern sky ; 

 with it stars too faint to be seen with the 15-iuch refractor have been 

 photographed, and a corresponding advantage is anticipated from the 

 increase of the aperture to 24 inches. 



Volume 17 of the Annals is now completed and consists of the follow- 

 ing papers, which have been separately printed and distributed during 

 the last few years : I. Magnitudes of stars employed in various nautical 

 almanacs; II. Discussion of the Urauometria Oxoniensis; III. Photo- 

 metric observations of asteroids ; IV. Total eclipse of the moon, 1888, 

 January 28; V. Total eclipse of the sun, 188G, August 29; VI. Detection 

 of new nebuhe l»y photography ; VII. A photographic determination of 

 the brightness of the stars; VIII. Index to observations of variable 

 stars; IX. Meridian-circle observations of close north polar stars ; X. 

 Meridian circle observations of close south polar stars. 



Volume 21, part 1, contains the observations of the New England 

 Meteorological Society made during 1888. Volume 22 contains a long 

 series of meteorological observations maele on the summit of Pike's 

 Peak, Colorado, between January, 1874, and June, 1888, by U. S. Army 

 Signal Service observers.
