These calculated places agree remarkably well with the ob- 

 servations at the first appearance of the meteor^ but ia the obser* 

 yations at the time of the disappearance, there is a considerable 

 discrepance^ and it is not possible wholly to reconcile the obser- 

 vatious at Baltimore with those made at other places. This diffi- 

 culty may have arisen partly from the circumstance that the J^alti- 

 more observations were not given immediately upon the appear- 

 ance of the meteor^ wlien the recollection of it was fresh in the 

 memory, but after the lapse of several weeks, when some of the 

 circumstances might have been forgotten : and of course greater 

 differences were to be expected in them than in the other observa- 

 tions. In calculating the apparent altitudes of the meteor, the 

 ten estrial refraction was supposed to be equal to ^V part of the 

 angle formed at the centre of the earth hy the lines drawn to the
