decreased to between 15° and 17°, or even less, at the time of its 

 separation. He adds, that he is not much accustomed to such ob- 

 servations. Mr A. D. Stevenson, living in South Portland Street, 

 Glasgovff, saw the meteor moving along, at a height just sufficient to 

 clear the chimney-tops, on the west side of the street, an elevation 

 which he afterwards estimated, as he states, with considerable accu- 

 racy at 28°. I have received farther and more minute accounts of 

 the appearance of the meteor from Mr Stevenson, who has been most 

 kind and intelligent in his communications ; and my friend Mr James 

 Peddie has verified the accuracy of Mr Stevenson's observations be- 

 yond the possibility of mistake. It appears that the meteor passed 

 quite clear of a stack of chimneys on the opposite side of the street, 

 which would give it a well-defined minimum altitude of 25° 41' ; but 

 Mr Stevenson is of opinion that it rose more than 2^ higher, or to 

 not less than 28° (perhaps even to 28° 21') ; when it was highest, 

 its bearing was 52 J° W. of N. (magnetic), and it disappeared from 

 his view when it bore 40° 27' E. of magnetic N. It was then de- 

 cidedly single. Now, this bearing coincides with that at which Mr 

 Gourlie observed it to become double ; and, consequently, the limit 

 towards the N. of this event is severely defined.
