INDUSTRIAL PROGRESS DURING THE YEAR 1871. xxiii 



of Union College, Schenectady, now have a controlling voice. 

 We believe that there is now in this country no observatory 

 of any importance, except that at Washington, which is not 

 more or less directly connected with a college or university. 



Turning to Foreign Observatories, American astronomers 

 have regretted to learn of the resignation of Dr. Francis 

 Brtinnow, Astronomer Royal of Ireland, and director of the 

 observatory at Dunsink, near Dublin. His successor, Pro- 

 fessor R. Ball, was formerly assistant to Lord Rosse, and sub- 

 sequently Professor of Applied Mathematics at Dublin. It 

 will be remembered that Dr. Briinnow was at one time di- 

 rector of the Observatory of Ann Arbor, Mich. 



The erection of a monument to the memory of Jeremiah 

 Horrocks has been suggested by Professor Adams, and an 

 appropriate tablet will be placed in Westminster Abbey. 



The publication of the Annals of the Paris Observato- 

 ry, comprising the volumes of memoirs, observations, and 

 charts, has been vigorously entered upon, and Volume X., 

 containing Le Verrier's theory of the mutual actions of Jupi- 

 ter and Saturn, has already appeared. The very instructive 

 works of Andre and Rayet, on the Observatories and Prac- 

 tical Astronomy of England, America, etc., are well worthy 

 of notice in this place. The Paris Observatory is being 

 equipped with a four-foot reflector, and a very large refract- 

 or (probably 29 inches) ; a magnetic observatory has also 

 been established at a short distance. 



The German government, in the development of its new 

 university at Strasburg, has not forgotten to endow it with 

 physical and chemical laboratories and an observatory, which 

 latter, under the directorship of Professor Winnecke, will 

 undoubtedly take a high rank. A refractor of 20-inch aper- 

 ture has been built for it by Merz & Mahler. The same 

 government has further shown its determination to keep the 

 lead which it has long maintained in astronomical matters 

 by the erection of an observatory at Potsdam devoted espe- 

 cially to the study of the sun. The English government 

 has been repeatedly urged to take a similar step in the inter- 

 ests of meteorology and magnetism as well as of astronomy, 

 and it is not impossible but that it will erect such an estab- 

 lishment at some favorable point in India.
