May, 1 1877, I found 76 slightly less than 82 and 86 Yirginis, 

 which Heis rated 6 m. 



April 6, 1883, 76 2 steps less than 82 Yirginis. 

 April 7, 1883, do. do. do. 



April 9, 1883, do. do. do.

 (= S) Ap. 4, 1878 {private letter); 3-36 Pritchard (1882 363). 3-53 

 H.P. 



April 26, 1876, I found l distinctly brighter than 8 ; ^ about 3 m. 

 August 2, 1877, same as last observation. 



March 12, 1880, C distinctly brighter than S, though at a much 

 lower altitude. 



April 5, 1883, I about three steps brighter than S, but less than y.
