140 Occult ations. 



of the preceding catalogue, where a wide double star is spoken 

 of as bringing up the rear of a group of interesting objects. 

 The brighter of the two is 4 Argus, a single yellowish 6 mag. 

 star ; the other will be easily decompounded into a beautiful 

 pah* : — 



121. 2 Argus. 16"' 8, 338 a *8, 7 and 7|. Silvery white and 

 pale white, 1836"2. I thought the smaller star bluish, 1851 '19, 

 1 864*1. This fine object is supposed to be stationary. 



122. About IF to the S., a wide 7 mag. pair, not men- 

 tioned in the Bedford catalogue, is worthy of notice from the 

 striking similarity of its components in size and hue — a deep 

 orange. There can be no faith whatever in appearances, 

 if these two peculiar looking individuals, insulated from any 

 near neighbours, though projected accidentally as it seems 

 upon a rich background in the distance, are not physically con- 

 nected. Their aspect at once as much bespeaks their binary 

 character as does that of 6 1 Cygni, and there is great probability 

 that an investigation into their parallax and proper motion, as 

 well as their distance and angle, would lead to an interesting 

 result. Their situation, however, commends them preferably to 

 the notice of southern observers. 



OCCULTATIO^S. 

 March 18. A 1 Cancri, 6 mag., will disappear at 6h. 58m., and 

 re-appear at 7h. 57m. A 2 Cancri, a similar star, will follow it 

 at 9h. 44m., and 1 lh. 4m. respectively. — 19th. a> Leonis will be 

 hidden from oh. 11m. till 7h. 28m. See the remarks on the 

 occultation of this star in Int. Obs., Dec. 18G3, p. 352. The 

 ] i resent is a more favourable opportunity for this curious obser- 

 vation, as the disappearance takes place at the dark limb; the 

 position of the limb, compared with the position-angle of the 

 two stars, seems also well adapted for a successive extinction of 

 the light of each component. — 27th. <o l Scorpii, 4| mag., will 

 disappear at 12h. 3m., and will remain invisible for lh. 2m.
