152 On Contemporaiieous Meteorological Observations. 



position, is, that though red single stars are common enough, 

 no example of an insulated blue, green, or purple one has yet 

 been produced. 



The three remaining sections of this paper comprise obser- 

 vations of the second comet of 1825 ; an account of the actual 

 state of the great nebula in Orion, compared with those of 

 former astronomers ; and observations of the nebula in the 

 girdle of Andromeda. The account of the comet, and that of 

 the great nebula in Orion, are accompanied with illustrative 

 drawings, and the latter also with a kind of map representing 

 the whole as a constellation, in which the parts are named 

 agreeably to a rude resemblance which the whole nebula pre- 

 sents to the head, snout, and jaws of some monstrous animal. 

 Aided by these drawings, the verbal account presents an in- 

 structively perspicuous description of the truly interesting 

 phaenomenon to which it relates.
