06 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



near his late opposition in the fall of 1877, and one or two of Saturn 

 at and near the time of the edge presentation of its ring, one show- 

 ing sonic bright spots or apparent thickening of the ring in places. 



The only other recorded observations of any importance were 

 made during the transit of Mercury, May G, 1878, during which first 

 and second contacts were observed. The others were lost by clouds. 



Lowell, Mass. : Private Observatory of 0. C. Wendell, Esq. 



My instrumental equipment consists of a fine Equatorial, by Alvan 

 Clark & Sons, of G^ inches aperture, and about 7^- feet focus, which 

 is unused at present for want of a suitable building. I also have the 

 loan of a portable Clark Telescope, of 3^ inches aperture, with which, 

 among other work, observations were made at the transit of Mercury 

 on May G. 



Recently my attention has been directed to meteoric astronomy 

 and variable stars. 



By a concerted arrangement with a Boston party, observations are 

 made by each of us every fair evening, when it is not bright moon- 

 light, on shooting-stars for the determination of heights and radiants. 



Some work has also been done on variables by naked-eye estima- 

 tions. 



Lately, however, Professor Pickering, of Harvard College Observa- 

 tory, has been kind enough to lend me a Zollner's Photometer, and it 

 is probable that work upon variable stars will be continued during 

 the ensuing year. 



Meteoric astronomy will also receive its share of attention as here- 

 tofore. 



Mt. Lookout, 0. : Cincinnati Observatory. 



Professor Ormoxd Stone, Director. 



1. Personnel. Ormond Stone, Director ; Herbert A. Howe, assist- 

 ant ; II. V. Egbert, student. 



2. Observations. With the Munich Refractor the revision of the 

 double stars between and 30 south declination has been contin- 

 ued. The working-list contains 941 stars, of which 389 have thus 

 far been observed at least twice, and 212 once, leaving 340 unob- 

 served. Two smaller working-lists have also been employed. These 

 contain polar and equatorial stars suitable for the determination of 

 personal equation. During September a short series of micrometri- 

 cal measurements of Saturn's satellites was obtained. 



With the Buff & Berger Transit, besides observations for the reg- 

 ulation of the standard time of Cincinnati, a series of observations has 

 been made for the determination of the latitude of the observatory. 



The sun has been examined with a Clark Refractor on 147 days; 

 spots vvere visible on 23 only.
