77 inches. For the photographic correction the crown glass component 

 was reversed and separated from the flint component by 1.7 inches; the 

 photographic focal length was only 65.6 inches. 91 



In 1895, five years after Floyd's death, his daughter donated the 5-inch 

 telescope to the Lick Observatory. 95 Although apparently never mounted 

 on Mount Hamilton, the Floyd telescope was taken on several solar 

 eclipse expeditions. At the Floyd's first fair weather eclipse — that of 22 

 January 1 898 — it was used for photographing the general features of the 

 corona; according to W. W. Campbell, it was "a splendid instrument 

 for the purpose." 96 



The astronomical observatory of Franklin and Marshall College 

 in Lancaster, Pennsylvania, was built and furnished in 1885-86. The 

 main dome enclosed a Clark 1 i-inch objective equatorially mounted by 

 Repsold & Sons of Hamburg, Germany. 97 



Dave Garroway, of New York City, bought the 9/2-inch aperture 

 Clark-Warner & Swasey equatorial from Beloit College (q.v. ) in 1967. 



Winthrop S. Gilman, Jr., a banker living in Palisades, Rockland Co., 

 New York, enthusiastically used several Clark instruments. He observed 

 the 1869 total solar eclipse with his 4-inch Clark achromat equipped 

 with a ruled micrometer glass which gave position angles for every 45 °; 

 the mounting was Clark's "usual portable equatorial, without circles or 

 clockwork." 98 Some of Gilman's other observations were reported in let- 

 ters to the director of the Harvard College Observatory. These letters re- 

 corded "sunspots as seen August 14, 1868 in a 9-inch glass of Alvan 

 Clark's make," as well as various observations with Tasker Marvin's 

 5-inch (q.v.) and Jacob Campbell's 12-inch (q.v.) Clark lenses. 99
