56 ANNUAL HECOIiD OF SCIENCE AND INDUSTRY. 



In its turn, the Litchfield Observatory already has become the ba- 

 sis of several longitudes in the state, determined under the auspices 

 of the Kegents of the University at Buffalo, Syracuse, Elmira, Og- 

 densburgh, and of the longitude of the Detroit Observatory, which 

 latter forms the fundamental point for the longitudes of the Lake 

 Survey. The latest work of this kind has been to determine the 

 longitude of the -western boundary of the State of New York. 



Besides, the observatory has a Sidereal Chronometer, constructed by 

 the same makers, with Habtnup's improved combination balance : 

 this instrument was the gift of the late Hon. George Underwood, 

 of Auburn. 



A Morse Telegraph Apparatus also has been presented by the late 

 S. W. Ciiubbuck, of Utica, and an Aneroid Barometer by the late Sim- 

 eon Benjamin, of Elmira. 



In order to observe the total eclipse of the sun, August 7, 18G9, 

 Mr. Ed-win 0. Litchfield presented a fine Portable Telescope. The 

 Telescope, made by Messrs. Steinheil Sons, of Munich, has 4 

 (French) inches aperture, 5 feet focal length, and is mounted par- 

 allactically on a solid iron tripod. It has two terrestrial and six 

 astronomical Eye-pieces (varying in power from 40 to 8G0), a Ring 

 and a Scale Micrometer, and a sliding -wedge for moderating the 

 light. There is, moreover, fitted to the eye-tube a direct-vision Spec- 

 troscope, -with five prisms, for analyzing the light of the sun and its 

 protuberances. This instrument is particularly useful for the exer- 

 cises of students who may make astronomy a special study. 



Another Portable Telescope, of the comet-seeker construction, was 

 brought from Europe by the director four years ago. It was made by 

 Mr. Hugo Sciiroeder, of Hamburg, and its object-glass has 5 inches 

 aperture. There are five Eye-pieces, varying in power from 25 to 

 275, with a Ring Micrometer, and a prism for more convenient ob- 

 servation. The telescope is mounted as an alt-azimuth.

Position and Description of the Observatory. The latitude of the ob- 

 servatory is 38 5G' north, and its longitude is l h l m G s west from 

 Washington. 



The building, which is frame, is forty-four feet long from east to 

 west, fourteen feet wide, fourteen feet high in the Equatorial room, 

 which is at the west end, and ten feet high in the Transit room. It 

 is situated eighty-six feet west of the main university edifice, and 

 fronts cast. The Equatorial room is surmounted by a roof in the
