No signs of 2's companion: image fine. At about 11 Ii. Procyon examined 

 by Professor J. C. Watson, and Holden. Where Ah'an G. Clark found a 

 companion (see Observing Book, Nor. 12, 1874), wliich was verified by llolden 

 (1874, Nov. 25 and Nov. 20), Professors Watson and Holden found tlirce. 

 One of tliese is somewiiat brigliter than tlie other two (see sketclies I. and II.), 

 an(i tiiis was first seen by Professor Watson (i.e., on Jan. 12), while Holdex 

 saw tiie precedliKj one; and, finally, all tliree were well seen, and tlie first seen 

 was measured in botli positions of the instrument east and west of the pier, by 

 both observers. The seeing was extremely fine, and these images were well 

 and steadily seen for about two hours (till Vd h.). In the sketches, a is the old 

 companion, p = 312° [s = 42"].

Holden suspects a 4th comjianion somewhere about p = 320° — 330°. It 

 should be noted further that 400 and 400 A are different eye-pieces, and that 

 these satellites were seen in all parts of the field of view, and in all positions of 

 the eye-piece. 



(21) New companions to Procyon : 1876, Jan. 20. The seeing is not good. 

 Reading for position angle : 



214° Holden p = 28° 

 224 Peters p = 18 

 212 Watson p = 30 



189° Peters p = 53° 

 188 Watson- p = 54 



242° Peters p = 0° 



Saw the brightest of the throe companions without difficulty and quite 

 steadily, and caught occasional glimpses of one of the others. 1). P. Toud. 



Neither Peters, Watson, nor Holden see 0.2's companion. 



(22) Companions of Procyon : 1870, Jan. 21. 10 h. 11 m. Examined 

 Procyon witli power 400. Imnges generally blurred and flaring. 

 Irregular whiffs of wind. During occasional moments caught quite 

 distant glinipses of one or two comi)anions about p 45° greater than 

 old companion, but too unsteady to meitsure. [p = 357°j Nkw-
