Probable error for unit weight, ± .0013 mm. = ±".018. 

 Annual proper motion in R. A., + ".026 ±".005. 

 Relative parallax, + ".024±".008. 



No other determination of this parallax has been published. The total proper motion 

 that we give for this star in Table 1 was derived from an examination of the star catalogues. 

 The companion is two magnitudes fainter and distant 13". The two are relatively fixed. 



(50 3) Weisse 1190, 19 h 49 ra , +1°41'. 



+14.30 c+ 26.19 m-3.74 7t=+ 0.0107 mm. c=+0.0005mm.

Probable error for unit weight, ± .0020 mm. = ±".029. 

 Annual proper motion in R. A., + ".017 ±".006. 

 Relative parallax, + ".018±".011. 



No other determination of this parallax has been published. Porter gives — 0".013 for 

 the proper motion. 



This star was first referred to four comparison stars of which Weisse 1196 was one. When 

 attention was called to the large proper motion of the latter, it was omitted as a comparison 

 star and from the same measures the parallax of Weisse 1190 was deduced. Weisse 1196 was 

 also referred to the same three comparison stars with the results given on the next page. See 

 Astronomical Journal, No. 776.
