Dr, Herschel's Astronomical Observations ^ &c, 249 
I. Of Stars in remarkable situations with regard to Nebulce,^ 
Among the great number of stars, with nebulosity dispersed 
between them are some in situations that deserve to be re- 
marked. 
IV, 5 is “ A pretty bright star situated exactly north of the 
“ center of an extended milky ray, which is about 15 or *0 
“ minutes in length." By a second observation, two years 
after the first, it appeared that the star was then included in 
part of the nebulosity. 
V, 46 is “ A pretty bright star in the middle of a very bright 
“ nebula, about 10 minutes in length and a' broad." See 
fig. 1. 
Ill, 616 is A star of the 6th magnitude, about 5' north of 
“ a very faint nebula, of an irregular figure." By an obser- 
vation of the same star, two years before, the two objects were 
then so near each other, as, at first sight, to cause a suspicion 
that some damp had settled upon the eye-glass and afiected 
the star. 
The singularity that five stars should be similarly situated 
with regard to nebulae is not very striking; but the difference 
in the additional observation is worthy of notice, and may 
suggest a surmise that nebula may have considerable proper 
motions, by which they are occasionally carried towards neigh- 
bouring stars: the difference in the clearness of the atmosphere

places of these objects will be found in three catalogues of nebulze and clusters of stars, 
published in the Philosophical Transactions for 1786, 1789, and 1802. The refer- 
ence IV, 5 for instance, points out number 5, in the IVth class.
