originally made by the Clarks for the telescope of Jefferson College 

 (q.v.). 



Thomas William Webb counted among his common telescopes a 

 refractor with a Clark objective of 51/2 inches aperture and 7 feet focus. 

 Acting on the advice of W. R. Dawes (q.v.), Webb purchased this 

 telescope in 1859 and used it for observations of the great comet two 

 years later. 24S In 1886, after Webb's death, the telescope was sold to 

 Stonyhurst College (q.v.). 



William Harvey Wells, as mentioned above (p. 19), was the 

 Clarks' first telescope customer. His 5-inch refractor, mounted in 1848, 

 showed the three stars of y Andromeda and sometimes the sixth star in 

 the trapezium of Orion. 240 



There are two equatorial refractors in the Whitin Observatory at 

 Wellesley College. The larger is the 12-inch Fitz/Clark telescope, 

 formerly owned by Jacob Campbell (q.v.) and Stephen V. C. White 

 (q.v.). Sarah Frances Whiting, Wellesley's first astronomer, had been 

 envious of this telescope since her teaching days in Brooklyn when she 

 had taken her students to look through it — through the finest glass in 

 the vicinity. 250 The other Wellesley instrument is a 6-inch telescope 

 marked at the eye-end "ALVAN CLARK & SONS CAMBRIDGE- 

 PORT, MASS. 1890"; the mount, which is probably of a later date, is 

 marked "ALVAN CLARK & SONS CO." 



Oliver Clinton Wendell, a Harvard astronomer, had a 6 / 2 -inch 

 Clark equatorial refractor in his Lowell observatory by 1878. He also 

 had, on loan, a portable 3 I />-inch Clark refractor. 251 As none of their 

 diaries or private correspondence has yet been found, it is difficult to 

 discover much about the Clarks' personal lives. It is apparent, however, 

 that Wendell was especially friendly with the Clarks. The obituary of 

 Alvan Graham that Wendell wrote for The Cambridge Tribune was 

 prepared at the request of the family, as one who stood near him. It,
