mount by Phelps. 13 " Six years later Jefferson College merged with the 

 nearby Washington College to form Washington and Jefferson College 

 (q.v. ), and soon thereafter the scientific work and equipment were 

 moved to the campus at Washington, Pennsylvania. 



The College des Jesuites in Quebec is the present owner of the 

 8-inch Clark equatorial refractor originally mounted in the Canadian 

 observatory on Bonner's Hill (q.v.). 



Joliet High School in Joliet, Illinois, has had a 4/ 2 -inch Clark 

 equatorial refractor since at least 1891. 133 



In 1 855 Baron de Rottenburg ordered a Clark telescope for subscribers 

 in Kingston, Canada West. This 6 ^4 -inch refractor, on a plain equatorial 

 mount, sold for $850. 134 Six years later the Kingston Observatory, 

 with its apparatus, was transferred to Queen's University (q.v.) in 

 Kingston, where it is yet. The Clark telescope has only recently been 

 retired. 



In 1857 George Knott, of Sussex, England, wrote to W. R. Dawes 

 (q.v.) in search of a suitable telescope for his private use. Dawes' reply 

 was an offer of the 7 5/3 -inch refractor Clark was then constructing for 

 him, together with his Munich equatorial mount. Two years later, when 

 Alvan Clark brought him a replacement, Dawes sold the 7 /3-inch to 

 Knott. 135 



Knox College in Galesburg, Illinois, acquired the 6-inch Clark equa- 

 torial, along with other instruments from Edgar Larkin's observatory 

 (q.v.) in 1888. This telescope was used, mainly for instruction, until the 

 college observatory was torn down a few years ago. 136 



An 8-inch Clark objective equatorially mounted by Repsold, was 

 erected at the Konigliche Universitats-Sternwarte in Breslau, Ger- 

 many, in 1898. 137
