ASTRONOMY. 45 



Work of Last Tear. Unfinished as the observatory was, work was 

 done during the year 1876 as follows : 



1. Regular time-observations were made. 



2. Meteorological records were made three times each day. 



3. Many occupations of stars were observed, and applied to the 

 determination of the longitude. 



4. Satellites of Saturn (3, 4, 5, 6) were specially observed from Sep- 

 tember till January. 



5. Much work was bestowed on the great nebula in Orion in the 

 latter part of the year. 



6. Many close double stars were observed by position-angle and 

 angular distance. 



7. Popular observations of the moon, planets, nebula?, clusters, 

 and double stars were very numerous, to meet the demands of vis- 

 itors. 



The observations on the Equatorial during the present year have 

 keen micrometric measures on close double stars and diameters of 

 planets, and position-angle and distance of satellites. Recently the 

 new satellites of Mars have been often observed. We are also con- 

 tinuing observations on satellites of Saturn. We have published 

 our observations on these satellites. 



Arrangements are in progress to determine our longitude by clock- 

 signals with the United States Naval Observatory. Our position, 

 as already approximately determined, is : Lat. 39 16' 17.5" N., long.

Private Observatory? Hartford, Conn,

This consists of a small framed building, with revolving dome 12 

 feet 6 inches in diameter. It contains a Telescope, by Alvan Clark 

 and Sons, with object-glass 9.4 inches clear aperture, mounted equa- 

 torially in the best manner. The instrument is used by its owner in 

 general observations of the moon, planets, and double stars, other 

 occupations preventing at present any more systematic work. The 

 object-glass is one of Mr. Alvan Clark's latest works, and is of the 

 highest excellence, exhibiting objects generally considered tests for 

 12 inches. 



The outer satellite of Mars was observed on two occasions after 

 the announcement of Professor Hall's discovery. An observation of 

 the bright spot which appeared upon Saturn in December, 1876, was 

 used by Hall in his determination of the rotation period of that 

 planet, and some new double stars have been found with this in- 

 strument.
