ASTRONOMY. 1 55 



Nova Andromedne, etc., and meteorological observations from 1882 to 

 1885 has been published. 



Smith College Observatory. — Professor Todd includes in bis report of 

 the Amherst Observatory a brief account of an observatory, the con- 

 struction of which he has supervised for the trustees of Smith College 

 (for young women), at Northampton, Massachusetts. A one-story brick 

 building is divided into an equatorial room, photographic dark-room, 

 library, clock-room, and transit-room. The equatorial is of 11 inches 

 aperture, the objective by the Clarks, and mounting by Warner & 

 Swasey. Incandescent lamps are provided for the illumination of the 

 circles and micrometers. The transit-room will contain a 4inch merid- 

 ian circle. The approximate position of the new observatory is : Lati- 

 tude, + 42° J 9' 1"; longitude, 4'^ 50>" 32«.9 west of Greenwich. 



South Evanston (1886). — Dr. Marsbali U. Ewell has erected a small 

 private observatory at South Evanston, Cook County, Illinois, 10.8 

 miles north of Chicago. The equatorial is a 6J-inch Clark refractor 

 mounted on a pier made of Portland cement and fine gravel so as to 

 form practically a single piece of rock from top to bottom. The dome 

 is 12 feet in diameter, built with ash ribs covered with tin, and turns 

 on six iron wheels. The observatory is also provided with a 2^ inch 

 Troughton & Simms transit, sidereal and mean-time chronometers, 

 and minor apparatus. 



Stockholm (1885). — Investigations upon the motions of the different 

 members of the solar system have absorbed the attention of the director 

 and his assistants. The mean motions of the apsides of the planets 

 Jupiter, Saturn, and Uranus are found to diifer sensibly from the 

 values assigned by Leverrier. Herr Shdauow has continued Gylddn's 

 researches upon the lunar theory, and Dr. Harzer has contributed a 

 valuable memoir upon the motion of Hecuba. 



Strasshurg. — Dr. Schur, previous to his departure for Gottingen, where 

 he takes Klinkerfues' place, published a report, dated May 6, 1880, sup- 

 plementary to his annual report of July, 1885. The principal meridian 

 work was upon southern stars in the extension of the Durchmusterung, 

 and Auwers' eighty-three southern fundamental stars and refraction 

 stars. The moon was observed with the altazimuth ; comets with the 

 refractor. Dr. Kobold succeeds Herr Schur. Dr. Winnecke has been 

 retired, at his own request, on account of ill health. 



Tacnhaya (1885) — The Observatorio Nacional, formerly at Chapulte- 

 pec, is now at Tacubaya, about G miles from the city of Mexico. The 

 final value of the longitude of the large meridian circle, from exchanges 

 in 1885 with St. Louis, is i,^ 36™ 46^54 ± 0«.02 west of Greenwich.

Taschlent (1885). — The refractor was employed principally in observ- 

 ing sun spots; comets and occultations were also observed. The merid- 

 ian circle furnished the places of a number of comparison stars for
