16 ANNUAL KECOKD OF SCIENCE AND INDUSTRY. 



at Cincinnati, that in 1871 the Astronomical Society, in con- 

 junction with the heirs of Nicholas Longworth, presented to 

 that city the former valuable site on Mount Adams, as well 

 as the instruments and library of the original observatory, on 

 condition that the city agree to maintain the institution for 

 scientific purposes, and in some new and appropriate location. 

 The new site was highly approved of by Professor Abbe, and 

 Avas donated by John Kilgour, Esq., who also added thereto 

 the sum often thousand dollars to provide for the new build- 

 ino-. this beinir an element in the improvement of a lars^e area 

 of land that he has laid out as a beautiful suburban park. 

 The observatory is now under the control of the Board of 

 Trustees of the University of Cincinnati, a body of about 

 twenty men, who are authorized to mould into a homogene- 

 ous institution the numerous bequests that the city has re- 

 ceived at various times for educational purposes. 



COLUMBIA COLLEGE OBSERVATORY. 



From a recent communication in Cap and Goioi, we learn 

 that there has been erected a small observatory on the Co- 

 lumbia College campus for educational and, we hope, also for 

 scientific purposes. The observatory is furnished with an 

 equatorial, accompanied by a seven-prism spectroscope, by 

 Clark, and a position micrometer, besides an altazimuth and 

 a zenith telescope. 



REGULATIOX OF TIME BY OBSERVATORIES. 



During the past few years inconveniences arising from the 

 constant changes of local time, and the conflicting errors of 

 local clocks on connecting railroads, have been felt with in- 

 creasing frequency by the traveling public, and still more by 

 the roads themselves. 



The aid of astronomical science has been lately invoked by 

 some of the leading railroads, and several observatories have 

 been requested to furnish exact time by the telegraph ; but 

 to how very great an extent abstract science has been thus 

 already utilized few even of those who benefit by it are per- 

 haps aware. 



From an article by Professor Langley, in the November 

 number of Silliman^s Journal^ describing the system intro- 

 duced at the Alleghany (Pittsburgh) Observatory, we learn
