ported by either end of an open arc frame which enclosed the right 

 ascension setting circle and many of the clock drive gears. The two 

 setting circles were finely engraved on silver and each was read under 

 two magnifying glasses. This telescope is now owned and used by the 

 Cincinnati Astronomical Society (q.v.) , 126 



John R. Hooper of Baltimore had a 5-inch Clark refractor of 1866 

 which was equatorially mounted and equipped with graduated circles 

 and a clock drive. 127 



Charles P. Howard acquired the 9.4-inch Clark telescope originally 

 owned by D. W. Edgecomb (q.v.) in 1880, and mounted it in his private 

 observatory in Hartford, Connecticut. Howard observed several solar 

 eclipses, including that of 28 May 1900, with the 2-inch aperture finder 

 of this instrument. 128 The large telescope was subsequently sold to some- 

 one in the Midwest, and the finder was sold to Roland Bourne (q.v.). 



The early spectroscopic discoveries of William Huggins were made 

 with starlight gathered by an 8-inch Clark object glass. 129 Huggins had 

 bought this lens from Dawes (q.v. ) in 1 858, had it remounted by Thomas 

 Cooke, and installed it in his observatory at Upper Tulse Hill, a suburb 

 of London. Ten years later, when a much larger instrument was being 

 made for him by Howard Grubb, Huggins sold the 8-inch to a Mr. 

 Corbett. 130 



When Jefferson College, at Canonsburg, Pennsylvania, was in the 

 market for a telescope they applied to Albert Hopkins of Williams Col- 

 lege for advice. 131 Hopkins recommended an instrument similar to the 

 one at Williams (q.v.) and by 1859 students at Jefferson College were 

 using a refracting telescope with a 7/0 -inch Clark lens and an equatorial
