244i SPECIAL RESULTS IN THE URANOLOGICAL 



mostly from the 14th to the 1 6th magnitude. The stars 

 form a series which is continued far beyond the nebula into 

 the Milky Way, where they are projected against, and 

 detach themselves from, the blackest background of sky. 

 They are, therefore, probably not connected with the nebula 

 itself, and may be very distant from it. The whole of the 

 adjacent portion of the Milky Way is, indeed, so rich in 

 stars (not star-clusters), that between 9 h 50 m and ll h 34 m 

 R. A., there have been found by " star-gauging" 3138 

 stars on an average to each square degree. This number 

 even rises to 5093 in the " sweeps" for ll h 24 E. A. ; being 

 more stars than are visible to the naked eye, (i. e. stars from 

 the 1st to the 6th magnitude), for the horizon of Paris or 

 that of Alexandria ( 43 ) . 



The nebula in Sagittarius. This nebula is of conside- 

 rable extent, and, as it were, composed of four distinct 

 masses (E. A. 17 h 53 ra N. P.D. 114 21'), one of which is 

 again subdivided into three. All are interrupted by places 

 devoid of nebulous appearance, and the whole had been im- 

 perfectly seen by Messier ( 431 ). 



The nebula in Cygnus. Consists of several irregular 

 masses, one of which forms a very narrow divided band 

 passing through the double star y Cygni. The connection 

 of these very dissimilar nebulous masses by a singular ap- 

 pearance of cellular texture was first perceived by Mason ( 432 ). 



The nebula in Vulpes. Was imperfectly seen by Mes- 

 sier, and is No. 27 of his list ; it was discovered on the 

 occasion of the observation of Bode's comet of 1779. The 

 exact determination of the position (E. A. 19 h 52 m , N. P. D. 

 67 43'), as well as the first drawing of this nebula, were 

 given by Sir John Herschel. It received the name of
