134. 38 Geminorum. 5"-8. 170°-7. 5* and 8. Light yellow 

 and purple (1839'17). This pair Sm. considered as probably 

 in motion, with a very slow period, which may be upwards of 

 2000 years. Its binary character has been confirmed by 

 Secchi, who gives, for 1856-112, 6"-137 and 169°'18, to be 

 compared with t's 5"- 736 and 174°-88, 1829'24, and J#'s 179°-9 

 in 1783. This beautiful object is pointed at by a line drawn 

 from Procyon through its wp comes j3 Can. Min. } but it must 

 be bent towards the S.; or it may be found by a line from

 we find a wide pair, If 1 , 5 mag., and |f 2 , 4 mag., about 2° f 

 from which lies 38.
