200 OBSERVATIONS ON NEBULJE 



bula on the right and left, and perhaps beneath, but is more open upward. 

 (Art. 18, Aug. 10.) 



6. The star 11 is too far down the preceding limb of the bend in Sir J. 

 Herschel's figure; it should be nearer the vertex. 



7. A slight protrusion from the upper curve of the bend involves the star 9. 



49. Stronghj suspected. — 1. Very faint nebulosity stretching across from star 

 25 to star 9, filling all the internal angle of the nebula. (Art. 18, Aug. 10.) 



2. Faint nebulosity extending from the stars 6 and 4 to or beyond star 2. 



3. A considerable, but faint diffusion of the nebula at the external angle 

 towards the north preceding. 



4. The fainter knot stretches still more faintly a little way downward. (Art. 

 18, Aug. 1.) 



5. Just above star 16 is a portion a little brighter than the rest of the bend. 



50. Slighthj suspected. — 1. An extension of the appearance mentioned in No. 

 4 of Art. 49, downwards, past stars 19 and 20. (Art. 18, Aug. 1 and 7.) 



2. A bare suspicion of nebulosity among a coarse cluster of stars between 

 11" and 11'" 30S and in about— 16° 8' or 10' Decl. (Art. 18, Aug. 7.) 



Nebula h. 2092 and 2093. 



51. Things certain. — 1. The brightest accumulation of nebulous matter is 

 within the triangle formed by stars 69, 83 and 93. 



2. Not much inferior to this in intensity is the portion included between the 

 bright stars 133 and 162. (Art. 19, Aug. 7.) 



3. The brightest loop of the network portion is a figure not altogether unlike 

 a Greek v, turned thus ce , and containing No. 2, just described. The first or 

 upper bend of this figure contains two curious triplets of stars, very similar 

 in position and magnitude ; the south following angle has in it a quintuple or 

 sextuple star, of which two individuals, 149 and 156, are about the minima 

 visihilia of the 14 feet reflector. (Art. 19, Aug. 9.) 



4. These two, No. 1 and 3, are the two great nuclea of the nebula. 



5. From the north following angle of the v, at the star 162, a branch pro- 

 ceeds southward, of brightness little inferior to that of the v; for the sake of 

 shortness, I call this 4', though possessing no resemblance to that letter. 



6. All the other loops and branches in this region except the v and ^ are 

 extremely faint.
