NEW POSITIONS OF STARS IN ORION 125 



PART VI. 



NOTES. 



1. In Professor G. P. Boud's catalogue [H. C. 0. Annals, Vol. V] 

 I find Herscliel 51 identified as Bond 575. The positions reduced to 1910.0 

 would in that ease be — 



Aa AS 



Herschel — 101".8 — 10".3 

 Bond —85.7 —22.0 



If, however, we identify Herschel 51 as Bond 567, a variable star which 

 is at times nearly as bright as 575, the positions are much closer. 



Therefore I have assumed the latter identification to be the correct one. 



2. The two measures made on 625 are very doubtful. Bond says in 

 his notes that he "siispeets" a faint star in the position given for 625. 

 During a series of observations to determine the magnitudes of the stars in 

 this region Professor Ormond Stone was unable to see any evidence of 625, 

 although he looked for it repeatedly. The two measures given in this paper 

 were exceedingly difficult and the object measured miay have been simply 

 a condensation in the nebula. 



3. During -the first six months of observation from September, 1908, 

 to February 26, 1909, the star 654 was invisible. After a period of cloudy 

 weather work was resumed on March 15, at which time 654 was quite bright. 

 The following comparison of brightness was made on that night : 



647 - 4 - 654 - 1 - 622 - 3 - 618. 



Throughout the rest of March 654 was about equal in brightness to 647. 

 As Orion was too near the sun for observation after April 1, the star was 

 not seen again until September 9. At that time it was very faint. On 

 November 10, 11 and 12, it was about at the limit of visibility and has not 

 been seen since.
