140 Astronomical Notes. 



pointed at by the three gems in the Giant's belt, at a distance 

 equal to their full extent, but lying somewhat n of the line. 

 yjr 1 itself is worth looking at for the beautiful low-power field 

 with its open pairs in which it is found. Our object, however, 

 lies rather further,/, a little n. It is $ 708. 2"*607. 323°*13. 

 8*2 and 9*8 (of his scale, equal to about 9 and 10| Sm.). 

 1831*81. It is pretty, though minute. 



Reverting to ^r x , we shall perceive, in the finder, about f 

 of a degree sp from it, three dim objects in a slightly curved 

 line pointing s, a little p, the brightest at the s end, the faintest 

 in the middle, but nearer s. Of these the n is 



128. 67 P.V., a wide and very unequal, but pleasing pair, 

 orange and blue. The s is 



129. 2 700. 4"-523. 5°*27. 8 and. 8 -2 (= full 9 Sm.). 

 White. 1831*48. Madler and Secchi's measures combine to 

 show its fixity. Secchi made them equal, 1857*104. I thought 

 them a little unequal, 1865*052. 



Two or three degrees to the S.E., nearly n of e, the central 

 gem of the belt, but a little/, in a situation forming a tolerably 

 isosceles triangle with e and 8, the uppermost gem, a little 

 sweeping will pick up a group of small stars, whose longest 

 axis lies nearly parallel to the equator, from which indeed it 

 is very little removed. This pretty configuration, which is all 

 in the field of a moderate power, bears a slight resemblance 

 to the constellation Sagitta. The stars are all white, and not 

 very unequal in size. The two last form a wide pair, our 



130. $ 758. ir-062. 297°*72. 8*5 and 9 (about 9 and 

 9|- Sm.). These, however, are much less beautiful than the 

 central object of the group, at 51" distance, which is 



131. t 757. r-683. 239°*83. 8 and 8*2 (perhaps 8£ and 

 9 Sm.). Secchi's observations in 1859 were only sufficient to 

 show that there has been no considerable motion in the group 

 during 28 years. Its insulated aspect would seem, however, 

 to bespeak comparative juxtaposition in space. 



Our list of Double Stars has contained so preponderating 

 an amount of easy objects that it would be only fair towards 

 such of our readers as possess instruments of considerable 

 power to introduce an occasional test of a higher class. Such 

 an one we are about to insert. 



132. 7) Orionis. This beautiful pair, which does not appear 

 in the Bedford Catalogue, was discovered by Dawes, Jan. 15, 



• 1848, who gave its approximate distance and position 1" and 

 87°, with mags. 4 and 5. Mr. Knott has favoured me with the 

 following recent measures:— 0"*947. 88°*83. (1863*12). It is a 

 serious objection to many of the more difficult pairs as tests, 

 that their orbital motion is continually altering their distance, 

 of which rj Coronce Borealis and 36 Andromedce, both now so
